Awesome

nb is a command line and local web note‑taking, bookmarking, archiving, and knowledge base application with:

• plain text data storage,
• encryption,
• filtering, pinning, #tagging, and search,
• Git-backed versioning and syncing,
• Pandoc-backed conversion,
• <a href="#-linking">[[wiki-style linking]]</a>,
• terminal and GUI web browsing,
• inline images,
• todos with tasks,
• global and local notebooks,
• organization with folders,
• customizable color themes,
• extensibility through plugins,

and more, in a single portable script.

nb creates notes in text-based formats like Markdown, Org, LaTeX, and AsciiDoc, can work with files in any format, can import and export notes to many document formats, and can create private, password-protected encrypted notes and bookmarks. With nb, you can write notes using Vim, Emacs, VS Code, Sublime Text, and any other text editor you like, as well as terminal and GUI web browsers. nb works in any standard Linux / Unix environment, including macOS and Windows via WSL, MSYS, and Cygwin. Optional dependencies can be installed to enhance functionality, but nb works great without them.

nb is also a powerful bookmarking system featuring:

• locally-served, text-centric, distraction-free bookmark browsing in terminal and GUI web browsers,
• local full-text search of cached page content with regular expression support,
• convenient filtering and listing,
• Internet Archive Wayback Machine snapshot lookup for broken links,
• tagging, pinning, linking, and full integration with other nb features.

Page information is downloaded, cleaned up, structured, and saved into normal Markdown documents made for humans, so bookmarks are easy to view and edit just like any other note.

nb uses Git in the background to automatically record changes and sync notebooks with remote repositories. nb can also be configured to sync notebooks using a general purpose syncing utility like Dropbox so notes can be edited in other apps on any device.

nb is designed to be portable, future-focused, and vendor independent, providing a full-featured and intuitive experience within a highly composable multimodal user-centric text interface. The entire program is contained within a single well-tested shell script that can be installed, copied, or curled almost anywhere and just work, using a strategy inspired by progressive enhancement for various experience improvements in more capable environments. nb works great whether you have one notebook with just a few notes or dozens of notebooks containing thousands of notes, bookmarks, and other items. nb makes it easy to incorporate other tools, writing apps, and workflows. nb can be used a little, a lot, once in a while, or for just a subset of features. nb is flexible.

macOS / Homebrew

brew install xwmx/taps/nb

Installing nb with Homebrew also installs the recommended dependencies above and completion scripts for Bash, Zsh, and Fish.

Install the latest development version from the repository with:

brew install xwmx/taps/nb --head

nb is also available in homebrew-core. Installing it together with the bash formula is recommended:

brew install nb bash

Ubuntu, Windows, and others

npm

npm install -g nb.sh

After npm installation completes, run sudo "$(which nb)" completions install to install Bash and Zsh completion scripts (recommended).

On Ubuntu and WSL, you can run sudo "$(which nb)" env install to install the optional dependencies.

When nb is installed on Windows, socat (MSYS, Cygwin) is recommended.

nb is also available under its original package name, notes.sh, which comes with an extra notes executable wrapping nb.

Download and Install

To install as an administrator, copy and paste one of the following multi-line commands:

# install using wget
sudo wget https://raw.github.com/xwmx/nb/master/nb -O /usr/local/bin/nb &&
  sudo chmod +x /usr/local/bin/nb &&
  sudo nb completions install

# install using curl
sudo curl -L https://raw.github.com/xwmx/nb/master/nb -o /usr/local/bin/nb &&
  sudo chmod +x /usr/local/bin/nb &&
  sudo nb completions install

On Ubuntu and WSL, you can run sudo nb env install to install the optional dependencies.

User-only Installation

To install with just user permissions, simply add the nb script to your $PATH. If you already have a ~/bin directory, for example, you can use one of the following commands:

# download with wget
wget https://raw.github.com/xwmx/nb/master/nb -O ~/bin/nb && chmod +x ~/bin/nb

# download with curl
curl -L https://raw.github.com/xwmx/nb/master/nb -o ~/bin/nb && chmod +x ~/bin/nb

Installing with just user permissions doesn't include the optional dependencies or completions, but nb core functionality works without them. If you have sudo access and want to install the completion scripts and dependencies, run the following command:

sudo nb env install

Make

To install with Make, clone this repository, navigate to the clone's root directory, and run:

sudo make install

This will also install the completion scripts on all systems and the recommended dependencies on Ubuntu and WSL.

bpkg

To install with bpkg:

bpkg install xwmx/nb

basher

To install with basher:

basher install xwmx/nb

Tab Completion

Bash, Fish, and Zsh tab completion should be enabled when nb is installed using the methods above, assuming you have the appropriate system permissions or installed with sudo. If completion isn't working after installing nb, see the completion installation instructions.

Updating

When nb is installed using a package manager like npm or Homebrew, use the package manager's upgrade functionality to update nb to the latest version. When installed via other methods, nb can be updated to the latest version using the nb update subcommand.

Overview

To get started, simply run:

nb

nb sets up your initial home notebook the first time it runs.

By default, notebooks and notes are global (at ~/.nb), so they are always available to nb regardless of the current working directory. nb also supports local notebooks.

📝 Notes

Adding

Use nb add (shortcuts: nb a, nb +) to create new notes:

# create a new note in your text editor
nb add

# create a new note with the filename "example.md"
nb add example.md

# create a new note containing "This is a note."
nb add "This is a note."

# create a new note with piped content
echo "Note content." | nb add

# create a new password-protected, encrypted note titled "Secret Document"
nb add --title "Secret Document" --encrypt

# create a new note in the notebook named "example"
nb example:add "This is a note."

# create a new note in the folder named "sample"
nb add sample/

nb add with no arguments or input will open the new, blank note in your environment's preferred text editor. You can change your editor using the $EDITOR environment variable or nb set editor.

nb files are Markdown files by default. The default file type can be changed to whatever you like using nb set default_extension.

nb add has intelligent argument parsing and behaves differently depending on the types of arguments it receives. When a filename with extension is specified, a new note with that filename is opened in the editor:

nb add example.md

When a string is specified, a new note is immediately created with that string as the content and without opening the editor:

❯ nb add "This is a note."
Added: [1] 20200101000000.md

nb add <string> is useful for quickly jotting down notes directly via the command line. Quoting content is optional, but recommended.

When no filename is specified, nb add uses the current datetime as the filename.

nb add can also receive piped content, which behaves the same as nb add <string>:

# create a new note containing "Note content."
❯ echo "Note content." | nb add
Added: [6] 20200101000100.md

# create a new note containing the clipboard contents on macOS
❯ pbpaste | nb add
Added: [7] 20200101000200.md

# create a new note containing the clipboard contents using xclip
❯ xclip -o | nb add
Added: [8] 20200101000300.md

Content can be passed with the --content <content> option, which also creates a new note without opening the editor:

nb add --content "Note content."

When content is piped, specified with --content <content>, or passed as a string argument, use the --edit flag to open the file in the editor before the change is committed.

The title, filename, and content can also be specified with long and short options:

❯ nb add --filename "example.md" -t "Example Title" -c "Example content."
Added: [9] example.md "Example Title"

The -t <title> / --title <title> option also sets the filename to the title, lowercased with spaces and non-filename characters replaced with underscores:

❯ nb add --title "Example Title" "Example content."
Added: [10] example_title.md "Example Title"

Tags can be added with the --tags <tag1>,<tag2>... option, which takes a comma separated list of tags, converts them to #hashtags, and inserts them between the title and content:

❯ nb add "Example content." --title "Tagged Example" --tags tag1,tag2
Added: [11] tagged_example.md "Tagged Example"

❯ nb show 11 --print
# Tagged Example

#tag1 #tag2

Example content.

Search for tagged items with nb search / nb q:

# search for items tagged with "#tag1"
nb search --tag tag1

# search for items tagged with "#tag1" AND "#tag2", short options
nb q -t tag1 -t tag2

# search for items tagged with "#tag1" OR "#tag2", arguments
nb q \#tag1 --or \#tag2

Files can be created with any file type by specifying the extension either in the filename (example.md), the extension by itself (.md), or via the --type <type> option (--type md):

# open a new Org file in the editor
nb add example.org

# open a new reStructuredText file in the editor
nb add --type rst

# open a new JavaScript file in the editor
nb add .js

Combining a type argument with piped clipboard content provides a very convenient way to save code snippets using a clipboard utility such as pbpaste, xclip, or pb:

# save the clipboard contents as a JavaScript file in the current notebook
pb | nb add .js

# save the clipboard contents as a Rust file in the "rust" notebook
# using the shortcut alias `nb a`
pb | nb a rust: .rs

# save the clipboard contents as a Haskell file named "example.hs" in the
# "snippets" notebook using the shortcut alias `nb +`
pb | nb + snippets: example.hs

Use nb show and nb browse to view code snippets with automatic syntax highlighting and use nb edit to open in your editor.

The clip plugin can also be used to create notes from clipboard content.

Piping, --title <title>, --tags <tag-list>, --content <content>, and content passed in an argument can be combined as needed to create notes with content from multiple input methods and sources using a single command:

❯ pb | nb add "Argument content." \
    --title   "Sample Title"      \
    --tags    tag1,tag2           \
    --content "Option content."
Added: [12] sample_title.md "Sample Title"

❯ nb show 12 --print
# Sample Title

#tag1 #tag2

Argument content.

Option content.

Clipboard content.

For a full list of options available for nb add, run nb help add.

Password-Protected Encrypted Notes and Bookmarks

Password-protected notes and bookmarks are created with the -e / --encrypt flag and encrypted with AES-256 using OpenSSL by default. GPG is also supported and can be configured with nb set encryption_tool.

Each protected note and bookmark is encrypted individually with its own password. When an encrypted item is viewed, edited, or opened, nb will simply prompt for the item's password before proceeding. After an item is edited, nb automatically re-encrypts it and saves the new version.

Encrypted notes can be decrypted using the OpenSSL and GPG command line tools directly, so you aren't dependent on nb to decrypt your files.

Shortcut Aliases: nb a, nb +

nb includes shortcuts for many commands, including nb a and nb + for nb add:

# create a new note in your text editor
nb a

# create a new note with the filename "example.md"
nb a example.md

# create a new note containing "This is a note."
nb + "This is a note."

# create a new note containing the clipboard contents with xclip
xclip -o | nb +

# create a new note in the notebook named "example"
nb example:a

Other Aliases: nb create, nb new

nb add can also be invoked with nb create and nb new for convenience:

# create a new note containing "Example note content."
nb new "Example note content."

# create a new note with the title "Example Note Title"
nb create --title "Example Note Title"

Adding with nb browse

Items can also be added within terminal and GUI web browsers using nb browse add / nb b a:

❯ nb browse add
❯nb · home : +

[                                                     ]
[                                                     ]
[                                                     ]
[                                                     ]
[                                                     ]
[                                                     ]
[                                                     ]
[                                                     ]
[                                                     ]
[                                                     ]

[add]

Pass a filename, relative path, and / or notebook name to create a new note at that location:

# open the add form in the browser to create the file "file.md" in the folder "example"
nb browse add "example/file.md"

nb browse add includes options for quickly pre-populating new notes with content:

❯ nb browse add --title "Example Title" --content "Example content." --tags tag1,tag2
❯nb · home : +

[# Example Title                                      ]
[                                                     ]
[#tag1 #tag2                                          ]
[                                                     ]
[Example content.                                     ]
[                                                     ]
[                                                     ]
[                                                     ]
[                                                     ]
[                                                     ]

[add]

nb browse add can also be opened with nb add --browse / nb a -b.

Listing & Filtering

To list notes and notebooks, run nb ls (shortcut alias: nb):

Notebooks are listed above the line, with the current notebook highlighted and/or underlined, depending on terminal capabilities. nb ls also includes a footer with example commands for easy reference. The notebook header and command footer can be configured or hidden with nb set header and nb set footer.

❯ nb ls
home
----
[3] example.md · "Example content."
[2] sample.md · "Sample content."
[1] demo.md · "- Demo list item one."

Notes from the current notebook are listed in the order they were last modified. By default, each note is listed with its id, filename, and an excerpt from the first line of the note. When a note has a title, the title is displayed instead of the filename and first line.

Markdown titles can be defined within a note using either Markdown h1 style or YAML front matter:

# Example Title

Sample Title
============

---
title: Demo Title
---

Org, LaTeX, and AsciiDoc titles are recognized in .org,.latex, and .asciidoc / .adoc files:

#+title: Example Org Title

\title{Example LaTeX Title}

= Example AsciiDoc Title

Once defined, titles are displayed in place of the filename and first line in the output of nb ls:

❯ nb ls
home
----
[3] Example Title
[2] Sample Title
[1] Demo Title

Pass an id, filename, or title to view the listing for that note:

❯ nb ls Sample\ Title
[2] Sample Title

❯ nb ls 3
[3] Example Title

If there is no exact match, nb will list items with titles and filenames that fuzzy match the query:

❯ nb ls exa
[3] Example Title

❯ nb ls ample
[3] Example Title
[2] Sample Title

Multiple words act like an OR filter, listing any titles or filenames that match any of the words:

❯ nb ls example demo
[3] Example Title
[1] Demo Title

When multiple words are quoted, filter titles and filenames for that phrase:

❯ nb ls "example title"
[3] Example Title

For full text search, see Search.

To view excerpts of notes, use the --excerpt or -e option, which optionally accepts a length:

❯ nb ls 3 --excerpt
[3] Example Title
-----------------
# Example Title

This is an example excerpt.

❯ nb ls 3 -e 8
[3] Example Title
-----------------
# Example Title

This is an example excerpt.

More example content:

- one
- two

Several classes of file types are represented with emoji indicators to make them easily identifiable in lists. For example, bookmarks and encrypted notes are listed with 🔖 and 🔒:

❯ nb ls
home
----
[4] Example Note
[3] 🔒 encrypted-note.md.enc
[2] 🔖 Example Bookmark (example.com)
[1] 🔖 🔒 encrypted.bookmark.md.enc

File types include:

 🔉  Audio
 📖  Book
 🔖  Bookmark
 🔒  Encrypted
 📂  Folder
 🌄  Image
 📄  PDF, Word, or Open Office document
 📹  Video

By default, items are listed starting with the most recently modified. To reverse the order, use the -r or --reverse flag:

❯ nb ls
home
----
[2] Todos
[3] Example Title
[1] Ideas

❯ nb ls --reverse
[1] Ideas
[3] Example Title
[2] Todos

Notes can be sorted with the -s / --sort flag, which can be combined with -r / --reverse:

❯ nb ls
home
----
[2] Sample Title
[3] Example Title
[1] Demo Title

❯ nb ls --sort
[1] Demo Title
[2] Sample Title
[3] Example Title

❯ nb ls --sort --reverse
[3] Example Title
[2] Sample Title
[1] Demo Title

nb with no subcommand behaves like an alias for nb ls, so the examples above can be run without the ls:

❯ nb
home
----
[2] Sample Title
[3] Example Title
[1] Demo Title

❯ nb example
[3] Example Title

❯ nb 3 --excerpt
[3] Example Title
-----------------
# Example Title

This is an example excerpt.

❯ nb 3 -e 8
[3] Example Title
-----------------
# Example Title

This is an example excerpt.

More example content:

- one
- two

❯ nb --sort
[1] Demo Title
[2] Sample Title
[3] Example Title

❯ nb --sort --reverse
[3] Example Title
[2] Sample Title
[1] Demo Title

Short options can be combined for brevity:

# equivalent to `nb --sort --reverse --excerpt 2` and `nb -s -r -e 2`:
❯ nb -sre 2
[3] Example Title
-----------------
# Example Title

[2] Sample Title
----------------
Sample Title
============
[1] Demo Title
--------------
---
title: Demo Title

nb and nb ls display the 15 most recently modified items. The default limit can be changed with nb set limit <number>. To list a different number of items on a per-command basis, use the -n <limit>, --limit <limit>, --<limit>, -a, and --all flags:

❯ nb -n 1
home
----
[5] Example Five
4 omitted. 5 total.

❯ nb --limit 2
home
----
[5] Example Five
[4] Example Four
3 omitted. 5 total.

❯ nb --3
home
----
[5] Example Five
[4] Example Four
[3] Example Three
2 omitted. 5 total.

❯ nb --all
home
----
[5] Example Five
[4] Example Four
[3] Example Three
[2] Example Two
[1] Example One

Lists can be paginated with -p <number> / --page <number>, which paginates by the value of nb set limit by default, or the value of -n <limit>, --limit <limit>, or --<limit> when present:

❯ nb
home
----
[6] Example Six
[5] Example Five
[4] Example Four
[3] Example Three
[2] Example Two
[1] Example One

❯ nb set limit 3
NB_LIMIT set to 3

❯ nb --page 1
[6] Example Six
[5] Example Five
[4] Example Four

❯ nb -p 2
[3] Example Three
[2] Example Two
[1] Example One

❯ nb -p 2 --limit 2
[4] Example Four
[3] Example Three

❯ nb -p 3 --2
[2] Example Two
[1] Example One

List #tagged items by passing \#escaped or "#quoted" hashtags or tags specified with the --tags option. Multiple tags perform an AND query:

# list items in the current notebook tagged with "#tag1", escaped
nb \#tag1

# list items in the "example" notebook tagged with "#tag2", quoted
nb example: "#tag2"

# list items in all notebooks tagged with "#tag1", long option
nb \#tag1 --all

# list items in the current notebook tagged with "#tag1" AND "#tag2"
nb \#tag1 "#tag2"

# list items in all notebooks tagged with "#tag2" AND "#tag3", short option
nb --tags tag2,tag3 -a

nb ls is a combination of nb notebooks and nb list in one view and accepts the same arguments as nb list, which lists only notes without the notebook list and with no limit by default:

❯ nb list
[100] Example One Hundred
[99]  Example Ninety-Nine
[98]  Example Ninety-Eight
... lists all notes ...
[2]   Example Two
[1]   Example One

For more information about options for listing notes, run nb help ls and nb help list.

Listing with browse

Items can be listed within terminal and GUI web browsers using nb browse / nb b:

❯ nb browse example:sample/demo/
❯nb · example : sample / demo / +

search: [                    ]

[example:sample/demo/7] Title Seven
[example:sample/demo/6] Title Six
[example:sample/demo/5] Title Five
[example:sample/demo/4] Title Four
[example:sample/demo/3] Title Three

Editing

You can edit an item in your editor with nb edit (shortcut: nb e):

# edit note by id
nb edit 3

# edit note by filename
nb edit example.md

# edit note by title
nb edit "A Document Title"

# edit note 12 in the notebook named "example"
nb edit example:12

# edit note 12 in the notebook named "example", alternative
nb example:12 edit

# edit note 12 in the notebook named "example", alternative
nb example:edit 12

edit and other subcommands that take an identifier can be called with the identifier and subcommand name reversed:

# edit note by id
nb 3 edit

nb edit can also receive piped content, which it appends to the specified note without opening the editor:

echo "Content to append." | nb edit 1

Content can be passed with the --content <content> option, which also appends the content without opening the editor:

nb edit 1 --content "Content to append."

Use the --overwrite option to overwrite existing file content and the --prepend option to prepend the new content before existing content.

When content is piped or specified with --content <content>, use the --edit flag to open the file in the editor before the change is committed.

Editing Encrypted Notes

When a note is encrypted, nb edit prompts you for the note password, opens the unencrypted content in your editor, and then automatically reencrypts the note when you are done editing.

Shortcut Alias: nb e

nb edit can be called by the shortcut alias, nb e:

# edit note by id
nb e 3

# edit note by filename
nb e example.md

# edit note by title
nb e "A Document Title"

# edit note by id, alternative
nb 3 e

# edit note 12 in the notebook named "example"
nb e example:12

# edit note 12 in the notebook named "example", alternative
nb example:12 e

# edit note 12 in the notebook named "example", alternative
nb example:e 12

For nb edit help information, run nb help edit.

Editing with browse

Items can be edited within terminal and GUI web browsers using nb browse edit / nb b e:

Viewing

Notes and other items can be viewed using nb show (shortcut: nb s):

# show note by id
nb show 3

# show note by filename
nb show example.md

# show note by title
nb show "A Document Title"

# show note by id, alternative
nb 3 show

# show note 12 in the notebook named "example"
nb show example:12

# show note 12 in the notebook named "example", alternative
nb example:12 show

# show note 12 in the notebook named "example", alternative
nb example:show 12

By default, nb show opens notes in less, with syntax highlighting if bat, highlight, or Pygments is installed. You can navigate in less using the following keys:

Key               Function
---               --------
mouse scroll      Scroll up or down
arrow up or down  Scroll one line up or down
f                 Jump forward one window
b                 Jump back one window
d                 Jump down one half window
u                 Jump up one half window
/<query>          Search for <query>
n                 Jump to next <query> match
q                 Quit

If less scrolling isn't working in iTerm2, go to "Settings" -> "Advanced" -> "Scroll wheel sends arrow keys when in alternate screen mode" and change it to "Yes". More Info

Use the -p / --print option to print to standard output with syntax highlighting:

❯ nb show 123 --print
# Example Title

Example content:

- one
- two
- three

Use nb show --print --no-color to print without syntax highlighting.

When Pandoc is available, use the -r / --render option to render the note to HTML and open it in your terminal browser:

nb show example.md --render
# opens example.md as an HTML page in w3m, links, or lynx

nb show also supports previewing other file types in the terminal, depending on the tools available in the environment. To prefer specific tools for certain file types, nb provides configuration variables that can be set in your ~/.nbrc file, which can be opened in your editor with nb settings edit.

Supported file types and tools include:

• Markdown files ($NB_MARKDOWN_TOOL):
  • bat
  • glow
  • mdcat
  • mdless
  • mdv
• PDF files:
  • termpdf.py with kitty
  • pdftotext
• Audio files ($NB_AUDIO_TOOL):
  • mplayer
  • afplay
  • mpg123
  • ffplay
• Images ($NB_IMAGE_TOOL):
  • catimg
  • Chafa
  • ImageMagick with a terminal that supports sixels
  • imgcat with iTerm2
  • kitty's icat kitten
  • termvisage
  • timg
  • viu
• Folders, Directories, Notebooks ($NB_DIRECTORY_TOOL):
  • eza
  • joshuto
  • lsd

• Excel, CSV, TSV, and data files ($NB_DATA_TOOL):
  • VisiData
  • sc-im
  • Tidy-Viewer (tv)
• EPUB ebooks:
  • Pandoc with w3m or links

When using nb show with other file types or if the above tools are not available, nb show opens files in your system's preferred application for each type.

nb show also provides options for querying information about an item. For example, use the --added / -a and --updated / -u flags to print the date and time that an item was added or updated:

❯ nb show 2 --added
2020-01-01 01:01:00 -0700

❯ nb show 2 --updated
2020-02-02 02:02:00 -0700

nb show is primarily intended for viewing items within the terminal. To view a file in the system's preferred GUI application, use nb open. To browse rendered items in terminal and GUI web browsers, use nb browse.

For full nb show usage information, run nb help show.

Shortcut Alias: nb s

nb show can be called using the shortcut alias nb s:

Markdown 1.0.1 (18 KB) — 17 Dec 2004

Introduction

Markdown is a text-to-HTML conversion tool for web writers. Markdown allows
you to write using an easy-to-read, easy-to-write plain text format, then
convert it to structurally valid XHTML (or HTML).

For more information, see Browsing.

Deleting

To delete one or more notes, pass any number of ids, filenames, titles, and other selectors to nb delete (shortcuts: nb d, nb -):

# delete item by id
nb delete 3

# delete item by filename
nb delete example.md

# delete item by title
nb delete "A Document Title"

# delete item by id, alternative
nb 3 delete

# delete item 12 in the notebook named "example"
nb delete example:12

# delete item 12 in the notebook named "example", alternative
nb example:12 delete

# delete item 12 in the notebook named "example", alternative
nb example:delete 12

# delete item 345 in the folder named "example"
nb delete example/345

# delete items with the ids 89, 56, and 21
nb delete 89 56 21

By default, nb delete will display a confirmation prompt. To skip, use the --force / -f option:

nb delete 3 --force

Shortcut Aliases: nb d, nb -

nb delete has the aliases nb d and nb -:

# delete note by id
nb d 3

# delete note by filename
nb d example.md

# delete note by title
nb - "A Document Title"

# delete note by id, alternative
nb 3 d

# delete note 12 in the notebook named "example"
nb - example:12

# delete note 12 in the notebook named "example", alternative
nb example:12 d

# delete note 12 in the notebook named "example", alternative
nb example:d 12

For nb delete help information, run nb help delete.

Deleting with nb browse

Items can be deleted within terminal and GUI web browsers using nb browse delete / nb b d:

❯ nb browse delete example:4
❯nb · example : 4 · ↓ · edit · - | +

              deleting

[4] example_file.md "Example Title"

              [delete]
 

For more information, see Browsing.

🔖 Bookmarks

nb includes a bookmarking system to conveniently create, annotate, view, search, browse, and manage collections of bookmarks.

Bookmarks in nb are stored as simple structured Markdown files containing information extracted from the bookmarked pages.

To create a new bookmark, pass a URL as the first argument to nb:

nb https://example.com

nb automatically generates a bookmark using information from the page:

# Example Title (example.com)

<https://example.com>

## Description

Example description.

## Content

Example Title
=============

This domain is for use in illustrative examples in documents. You may
use this domain in literature without prior coordination or asking for
permission.

[More information\...](https://www.iana.org/domains/example)

nb embeds the page content in the bookmark, making it available for full text search with nb search and locally-served, distraction-free reading and browsing with nb browse. When Pandoc is installed, the HTML page content is converted to Markdown. When readability-cli is installed, markup is cleaned up to focus on content. When Chromium or Chrome is installed, JavaScript-dependent pages are rendered and the resulting markup is saved.

Many shells automatically escape special characters in URLs. If a URL contains characters that are preventing it from being saved in full, URLs can also be enclosed in quotes when passed to nb:

nb "https://example.com#sample-anchor"

In addition to caching the page content, you can also include a quote from the page in a ## Quote section using the -q <quote> / --quote <quote> option:

nb https://example.com --quote "Example quote line one.

Example quote line two."

# Example Title (example.com)

<https://example.com>

## Description

Example description.

## Quote

> Example quote line one.
>
> Example quote line two.

Example Title
=============

This domain is for use in illustrative examples in documents. You may
use this domain in literature without prior coordination or asking for
permission.

Add a comment in a ## Comment section using the -c <comment> / --comment <comment> option:

nb https://example.com --comment "Example comment."

Add related URLs and linked selectors to a ## Related section using the -r (<url> | <selector>) / --related (<url> | <selector>) option:

nb https://example.com --related example:123 -r https://example.net

# Example Title (example.com)

<https://example.com>

This domain is for use in illustrative examples in documents. You may
use this domain in literature without prior coordination or asking for
permission.

[More information\...](https://www.iana.org/domains/example)

Bookmarks can be tagged using the -t <tag1>,<tag2>... / --tags <tag1>,<tag2>... option. Tags are converted into #hashtags and added to a ## Tags section:

nb https://example.com --tags tag1,tag2

# Example Title (example.com)

<https://example.com>

## Description

Example description.

## Tags

#tag1 #tag2

## Content

permission.

[More information\...](https://www.iana.org/domains/example)

Search for tagged bookmarks with nb search / nb q:

nb search --tag tag1

nb q -t tag1

nb q \#tag1

nb search / nb q automatically searches archived page content:

❯ nb q "example query"
[10] 🔖 example.bookmark.md "Example Bookmark (example.com)"
------------------------------------------------------------
5:Lorem ipsum example query.

Bookmarks can also be encrypted:

# create a new password-protected, encrypted bookmark
nb https://example.com --encrypt

Encrypted bookmarks require a password before they can be viewed or opened.

Listing and Filtering Bookmarks

Bookmarks are included in nb, nb ls, nb list, and nb browse along with items of other types. nb bookmark and nb bookmark list can be used to list and filter only bookmarks:

❯ nb bookmark
Add: nb <url> Help: nb help bookmark
------------------------------------
[3] 🔖 🔒 example.bookmark.md.enc
[2] 🔖 Bookmark Two (example.com)
[1] 🔖 Bookmark One (example.com)

❯ nb bookmark list two
[2] 🔖 Bookmark Two (example.com)

Bookmarks are also included in nb, nb ls, and nb list:

❯ nb
home
----
[7] 🔖 Bookmark Three (example.com)
[6] Example Note
[5] 🔖 Bookmark Two (example.net)
[4] Sample Note
[3] 🔖 🔒 example-encrypted.bookmark.md.enc
[2] Demo Note
[1] 🔖 Bookmark One (example.com)

Use the --type <type> / --<type> option as a filter to display only bookmarks:

❯ nb --type bookmark
[7] 🔖 Bookmark Three (example.com)
[5] 🔖 Bookmark Two (example.net)
[3] 🔖 🔒 example-encrypted.bookmark.md.enc
[1] 🔖 Bookmark One (example.com)

❯ nb --bookmark
[7] 🔖 Bookmark Three (example.com)
[5] 🔖 Bookmark Two (example.net)
[3] 🔖 🔒 example-encrypted.bookmark.md.enc
[1] 🔖 Bookmark One (example.com)

nb saves the domain in the title, making it easy to filter by domain using any list subcommands:

❯ nb example.com
[7] 🔖 Bookmark Three (example.com)
[1] 🔖 Bookmark One (example.com)

For more listing options, see nb help ls, nb help list, and nb help bookmark.

Shortcut Aliases: nb bk, nb bm

nb bookmark can also be used with the aliases nb bk and nb bm:

❯ nb bk
Add: nb <url> Help: nb help bookmark
------------------------------------
[7] 🔖 Bookmark Three (example.com)
[5] 🔖 Bookmark Two (example.net)
[3] 🔖 🔒 example-encrypted.bookmark.md.enc
[1] 🔖 Bookmark One (example.com)

❯ nb bm example.net
[5] 🔖 Bookmark Two (example.net)

Viewing Bookmarks

nb provides multiple ways to view bookmark files, bookmarked content, and bookmarked URLs.

Use nb browse (shortcut: nb b) to browse bookmarks with cached content, <a href="#-linking">[[wiki-style links]]</a>, linked #tags, and external links:

❯ nb browse text:formats/markdown/123
❯nb · text : formats / markdown / 123 · ↓ · edit | +

Markdown 1.0.1 (18 KB) — 17 Dec 2004

Introduction

Markdown is a text-to-HTML conversion tool for web writers. Markdown allows
you to write using an easy-to-read, easy-to-write plain text format, then
convert it to structurally valid XHTML (or HTML).

For more information, see Browsing.

nb open (shortcut: nb o) opens the bookmarked URL in your system's primary web browser:

# open bookmark by id
nb open 3

# open bookmark 12 in the notebook named "example"
nb open example:12

# open bookmark 12 in the notebook named "example", alternative
nb example:12 open

# open bookmark 12 in the notebook named "example", alternative
nb example:open 12

N.B. To use nb open with WSL, install wslu.

nb peek (shortcut: nb p, alias: nb preview) opens the bookmarked URL in your terminal web browser, such as w3m, Links, or Lynx:

# peek bookmark by id
nb peek 3

# peek bookmark 12 in the notebook named "example"
nb peek example:12

# peek bookmark 12 in the notebook named "example", alternative
nb example:12 peek

# peek bookmark 12 in the notebook named "example", alternative
nb example:peek 12

nb open and nb peek work seamlessly with encrypted bookmarks. nb simply prompts you for the bookmark's password.

nb open and nb peek automatically check whether the URL is still valid. If the page has been removed, nb can check the Internet Archive Wayback Machine for an archived copy.

The preferred terminal web browser can be set using the $BROWSER environment variable, assigned in ~/.bashrc, ~/.zshrc, or similar:

export BROWSER=lynx

When $BROWSER is not set, nb looks for w3m, links, and lynx and uses the first one it finds.

$BROWSER can also be used to easy specify the terminal browser for an individual command:

❯ BROWSER=links nb 12 peek
# opens the URL from bookmark 12 in links

❯ BROWSER=w3m nb 12 peek
# opens the URL from bookmark 12 in w3m

nb show and nb edit can also be used to view and edit bookmark files, which include the cached page converted to Markdown.

nb show <id> --render / nb show <id> -r displays the bookmark file converted to HTML in the terminal web browser, including all bookmark fields and the cached page content, providing a cleaned-up, distraction-free, locally-served view of the page content along with all of your notes.

Shortcut Aliases: nb o and nb p

nb open and nb peek can also be used with the shortcut aliases nb o and nb p:

# open bookmark by id
nb o 3

# open bookmark 12 in the notebook named "example"
nb o example:12

# open bookmark 12 in the notebook named "example", alternative
nb example:12 o

# peek bookmark by id
nb p 3

# peek bookmark 12 in the notebook named "example"
nb p example:12

# peek bookmark 12 in the notebook named "example", alternative
nb example:12 p

Bookmark File Format

Bookmarks are identified by a .bookmark.md file extension. The bookmark URL is the first URL in the file within < and > characters. To create a minimally valid bookmark file with nb add:

nb add example.bookmark.md --content "<https://example.com>"

For a full overview, see nb Markdown Bookmark File Format.

bookmark -- A command line tool for managing bookmarks.

nb includes bookmark, a full-featured command line interface for creating, viewing, searching, and editing bookmarks.

bookmark is a shortcut for the nb bookmark subcommand, accepting all of the same subcommands and options with identical behavior.

❯ bookmark https://example.com --tags tag1,tag2
Added: [3] 🔖 20200101000000.bookmark.md "Example Title (example.com)"

List and filter bookmarks with bookmark and bookmark list:

❯ bookmark
Add: bookmark <url> Help: bookmark help
---------------------------------------
[3] 🔖 🔒 example.bookmark.md.enc
[2] 🔖 Example Two (example.com)
[1] 🔖 Example One (example.com)

❯ bookmark list two
[2] 🔖 Example Two (example.com)

[10] 🔖 example.bookmark.md "Example Bookmark (example.com)"
------------------------------------------------------------
5:Lorem ipsum example query.

See bookmark help for more information.

✅ Todos

Use nb todo (shortcut: nb to) to create, list, and update todos. nb todos are structured Markdown documents referencing a single primary todo, with optional tasks.

Use nb todo add to create a new todo:

# create a new todo titled "Example todo one."
❯ nb todo add "Example todo one."
Added: [1] ✔️ [ ] Example todo one.

❯ nb show 1 --print
# [ ] Example todo one.

Use the --due <date> option to add an optional due date in a ## Due section:

# create a new todo titled "Example todo two." with a due date of "2100-01-01"
❯ nb todo add "Example todo two." --due "2100-01-01"
Added: [2] ✔️ [ ] Example todo two.

❯ nb show 2 --print

🏷 #tagging

nb recognizes #hashtags defined anywhere within a document. A hashtag is defined in nb as a # character followed by any number of letters, numbers, underscores, and dashes.

Notes and bookmarks can be tagged when they are created using the --tags <tag1>,<tag2>... option, which is available with nb add, nb <url>, nb browse add, nb bookmark, and nb todo. --tags takes a comma-separated list of tags, converts them to #hashtags, and adds them to the document.

Tags added to notes with nb add --tags are placed between the title and body text:

❯ nb add --title "Example Title" "Example note content." --tags tag1,tag2

# Example Title

#tag1 #tag2

Example note content.

Tags added to bookmarks with nb <url> --tags and nb bookmark <url> --tags are placed in a ## Tags section:

❯ nb https://example.com --tags tag1,tag2

# Example Title (example.com)

<https://example.com>

## Description

Example description.

## Tags

#tag1 #tag2

## Content

Example Title
=============

This domain is for use in illustrative examples in documents. You may
use this domain in literature without prior coordination or asking for
permission.

[More information\...](https://www.iana.org/domains/example)

Tags added to todos with nb todo add --tags are placed in a ## Tags section:

❯ nb todo add --tags tag1,tag2 "Example todo."

# [ ] Example todo.

## Tags

#tag1 #tag2

Use nb --tags, nb ls --tags, and nb list --tags to list the tags present in a notebook, folder, or item:

# list all tags found in items in the current notebook
nb --tags

# list all tags found in the folder named "example"
nb example/ --tags

# list all tags in the item with id 123 in the notebook named "sample"
nb sample:123 --tags

List tagged items by passing \#escaped or "#quoted" hashtags or tags specified with the --tags option to nb / nb ls:

# list items in the current notebook tagged with "#tag1", escaped
nb \#tag1

# list items in the "example" notebook tagged with "#tag2", quoted
nb example: "#tag2"

# list items in all notebooks tagged with "#tag3", long option
nb --tags tag3 --all

# list items in all notebooks tagged with "#tag3", short option
nb --tags tag3 -a

Combine multiple tags to search for items containing all specified tags:

# list items in the current notebook tagged with "#tag1" AND "#tag2"
nb \#tag1 "#tag2"

# list items in the current notebook tagged with "#tag2" AND "#tag3"
nb --tags tag2,tag3

# list items in all notebooks tagged with "#tag1" AND "#tag2" AND "#tag3" AND "#tag4"
nb \#tag1 "#tag2" --tags tag3,tag4 --all

Tagged items can be searched with nb search / nb q:

# search for items tagged with "#tag1"
nb search --tag tag1

# search for items tagged with "#tag1", shortcut and short option
nb q -t tag1

# search for items tagged with "#tag1", shortcut and argument
nb q \#tag1

# search for items tagged with "#tag1", shortcut and argument, alternative
nb q "#tag1"

# search for items tagged with "#tag1" AND "#tag2"
nb q --tag tag1 --tag tag2

# search for items tagged with "#tag1" AND "#tag2", short options
nb q -t tag1 -t tag2

# search for items tagged with "#tag1" AND "#tag2", arguments
nb q \#tag1 \#tag2

# search for items tagged with "#tag1" AND "#tag2", tag list
nb q --tags tag1,tag2

# search for items tagged with either "#tag1" OR "#tag2", options
nb q -t tag1 --or -t tag2

# search for items tagged with either "#tag1" OR "#tag2", arguments
nb q \#tag1 --or \#tag2

# search for items tagged with either "#tag1" OR "#tag2", single argument
nb q "#tag1|#tag2"

# search for items tagged with "#tag1" AND "#tag2" AND "#tag3"
nb q -t tag1 --tags tag2,tag3

# search for items tagged with "#tag1" OR "#tag2" OR "#tag3"
nb q -t tag1 --or --tags tag2,tag3

# search for items tagged with "#tag1" OR "#tag2" OR "#tag3"
nb q \#tag1 --or -t tag2 --or "#tag3"

Linked tags can be browsed with nb browse, providing another dimension of browsability in terminal and GUI web browsers, complimenting <a href="#-linking">[[wiki-style linking]]</a>.

Tags in notes, bookmarks, files in text-based formats, Word .docx documents, and Open Document .odt files are rendered as links to the list of items in the notebook sharing that tag:

❯nb · example : 321

Example Title

#tag1 #tag2

Example content with link to [[Sample Title]].

More example content:

- one
- two
- three

Use the -t <tag> / --tag <tag> option to open nb browse to the list of all items in the current notebook or a specified notebook or folder that share a tag:

# open to a list of items tagged with "#tag2" in the "example" notebook
❯ nb browse example: --tag tag2
❯nb · example

search: [#tag2               ]

[example:321] Example Title
[example:654] Sample Title
[example:789] Demo Title

# shortcut alias and short option
❯ nb b example: -t tag2
❯nb · example

search: [#tag2               ]

[example:321] Example Title
[example:654] Sample Title
[example:789] Demo Title

For more information about full-text search, see Search and nb search. For more information about browsing, see Browsing and nb browse.

🔗 Linking

Notes, bookmarks, files in text-based formats, Word .docx documents, and Open Document .odt files can reference other items using <a href="#-linking">[[wiki-style links]]</a>, making nb a powerful terminal-first platform for Zettelkasten, wiki-style knowledge mapping, and other link-based note-taking methods.

To add a link from a note or bookmark to another in the same notebook, include the id, title, or relative path for the target item within double square brackets anywhere in the linking document:

# link to the item with id 123 in the root level of current notebook
[[123]]

# link to the item titled "Example Title" in the root level of the current notebook
[[Example Title]]

# link to the item with id 456 in the folder named "Sample Folder"
[[Sample Folder/456]]

# link to the item titled "Demo Title" in the folder named "Sample Folder"
[[Sample Folder/Demo Title]]

To link to an item in another notebook, add the notebook name with a colon before the identifier:

# link to the item with id 123 in the "sample" folder in the "example" notebook
[[example:sample/123]]

# link to the item titled "Example Title" in the "demo" notebook
[[demo:Example Title]]

# link to the item with filename "Example File.md" in the "sample" notebook
[[sample:Example File.md]]

The text for a link can be specified after a pipe | character:

# render link to item 123 in the "example" notebook as [[Example Link Text]]
[[example:123|Example Link Text]]

<a href="#-linking">[[wiki-style links]]</a> cooperate well with Org links, which have a similar syntax, providing a convenient option for linking collections of Org files.

Linked items can be browsed with nb browse.

For more information about identifying items, see Selectors.

🌍 Browsing

Use nb browse (shortcut: nb b) to browse, view, edit, and search linked notes, bookmarks, notebooks, folders, and other items using terminal and GUI web browsers.

nb browse includes an embedded, terminal-first web application that renders <a href="#-linking">[[wiki-style links]]</a> and #hashtags as internal links, enabling you to browse your notes and notebooks in web browsers, including seamlessly browsing to and from the offsite links in bookmarks and notes.

❯ nb browse
❯nb · home : +

search: [                    ]

[home:6]  📌 Example Markdown Title

[home:4]  Example LaTeX Title
[home:3]  📹 example-video.mp4
[home:2]  example.md
[home:1]  📂 Example Folder

Lists are displayed using the same format as nb and nb ls, including pinned items, with each list item linked. Lists are automatically paginated to fit the height of the terminal window.

❯ nb browse example:sample/demo/
❯nb · example : sample / demo / +

search: [                    ]

[example:sample/demo/7] Title Seven
[example:sample/demo/6] Title Six

nb browse is designed to make it easy to navigate within terminal web browsers using only keyboard commands, while also supporting mouse interactions. The nb browse interface includes links to quickly jump to parent folders, the current notebook, and other notebooks.

nb browse opens in w3m, Links, or in the browser set in the $BROWSER environment variable. Use nb browse --gui / nb b -g to open in the system's primary GUI web browser.

To open a specific item in nb browse, pass the selector for the item, folder, or notebook to nb browse:

# open the item with id 42 in the folder named "sample" in the "example" notebook
❯ nb browse example:sample/42
❯nb · example : sample / 42 · ↓ · edit | +

Example Title

#tag1 #tag2

Example content with link to [[Demo Title]].

More example content:

  • one
  • two
  • three

Items can also be browsed with nb show --browse / nb s -b, which behaves identically.

nb browse is particularly useful for bookmarks. Cached content is rendered in the web browser along with comments and notes. Internal and external links are easily accessible directly in the terminal, providing a convenient, distraction-free approach for browsing collections of bookmarks.

Markdown 1.0.1 (18 KB) — 17 Dec 2004

Introduction

Markdown is a text-to-HTML conversion tool for web writers. Markdown allows
you to write using an easy-to-read, easy-to-write plain text format, then
convert it to structurally valid XHTML (or HTML).

Notes, bookmarks, files in text-based formats, source code, Word .docx documents, and Open Document .odt files are converted into HTML and rendered in the browser. Use the down arrow (↓) link to view or download the original file.

browse edit

Items in text formats can be edited within terminal and GUI web browsers using the edit link on the item page or by opening the item with nb browse edit / nb b e, which automatically resizes the form to fit the current terminal window:

❯ nb browse edit text:formats/markdown/123
❯nb · text : formats / markdown / 123 · ↓ · editing · - | +

Terminal web browsers provide different editing workflows. w3m opens items in your $EDITOR, then returns you back to the browser to save changes and continue browsing. Edits in links are performed directly in the browser.

Syntax highlighting, block selection, and other advanced editor features are available with nb browse --gui.

browse add

Add an item within the browser using the + link or nb browse add / nb b a. Pass a notebook, folder, and / or filename selector to create a new note in that location:

❯ nb browse add text:formats/
❯nb · text : formats / +

[                                                   ]
[                                                   ]
[                                                   ]
[                                                   ]
[                                                   ]
[                                                   ]
[                                                   ]
[                                                   ]
[                                                   ]
[                                                   ]

[add]

nb browse add includes options for quickly pre-populating new notes with content:

❯ nb browse add --title "Example Title" --content "Example content." --tags tag1,tag2
❯nb · home : +

[# Example Title                                    ]
[                                                   ]
[#tag1 #tag2                                        ]
[                                                   ]
[Example content.                                   ]

[                                                   ]

[add]

browse delete

Use the - link on the nb browse edit page or nb browse delete / nb b d to delete an item:

❯ nb browse delete example:4
❯nb · example : 4 · ↓ · edit · - | +

              deleting

[4] example_file.md "Example Title"

              [delete]
 

browse Search

nb browse includes a search field powered by nb search that can be used to search the current notebook or folder. Search queries are treated as command line arguments for nb search, providing the ability to perform AND and OR queries. Use the -q <query> / --query <query> option to open nb browse to the results page for a search:

# open to a list of items containing "example" in the current notebook
❯ nb browse --query "example"
❯nb · home

search: [example             ]

[home:321] Test Title
[home:654] Sample Title
[home:789] Demo Title

# using shortcut alias and short option
❯ nb b -q "example"
❯nb · home

search: [example             ]

[home:321] Test Title
[home:654] Sample Title
[home:789] Demo Title

Search for #tags with the -t / --tag / --tags options:

# open to a list of items tagged with "#tag2" in the current notebook
❯ nb browse --tag tag2
❯nb · home

search: [#tag2               ]

[home:654] Sample Title
[home:789] Demo Title

# using shortcut alias and short option
❯ nb b -t tag2
❯nb · home

search: [#tag2               ]

[home:654] Sample Title
[home:789] Demo Title

For more information about search options, see Search and nb search.

browse --gui

To open any nb browse view in the system's primary GUI web browser, add the nb browse --gui / nb b -g option:

# open the item with id 123 in the "sample" notebook in the system's primary GUI browser
nb browse sample:123 --gui

# open the folder named "example" in the system's primary GUI browser,
# short option
nb browse example/ -g

# open the current notebook in the system's primary GUI browser,
# shortcut alias and short option
nb b -g

browse --gui Editing

By default, nb browse --gui uses the browser's default <textarea> for editing items.

Ace is a text editor for GUI web browsers that provides advanced text editing functionality, including block selection and syntax highlighting.

To use Ace as the editor for nb browse --gui, add the following line to your ~/.nbrc file:

export NB_ACE_ENABLED=1

The next time a form is loaded in nb browse, nb will automatically download (from GitHub), install, and enable the Ace editor in nb browse edit --gui and nb browse add --gui.

browse Portability

nb browse depends on either socat or ncat (available as part of the ncat or nmap package in most package managers) and pandoc. When neither socat nor ncat is available and the Bash version is 5.2 or higher, nb browse falls back to a pure Bash implementation that supports all features except the Ace editor. When only pandoc is available, the current note is rendered and <a href="#-linking">[[wiki-style links]]</a> go to unrendered, original files. When socat,ncat, or Bash 5.2+ is available without pandoc, files in plain text formats are rendered with the original markup unconverted. If neither ncat, socat, Bash 5.2+, nor pandoc is available, nb browse falls back to the default behavior of nb show.

When nb is installed on Windows, socat (MSYS, Cygwin) is recommended.

browse Privacy

nb browse is completely local and self-contained within nb, from the CSS and JavaScript all the way down through the HTTP request parsing and response building, with no imports, libraries, frameworks, or third-party code outside of the few binary dependencies (bash, git, ncat / socat, pandoc), the Linux / Unix environment, and the optional Ace editor.

Terminal web browsers don't use JavaScript, so visits from them are not visible to some web analytics tools. nb browse includes a number of additional features to enhance privacy and avoid leaking information:

• Page content is cached locally within each bookmark file, making it readable in terminal and GUI web browsers without requesting the page again or needing to be connected to the internet.
• <img> tags in bookmarked content are removed to avoid requests.
• Outbound links are automatically rewritten to use an exit page redirect to mitigate leaking information via the referer header.
• All pages include the <meta name="referrer" content="no-referrer" /> tag.
• Links include a rel="noopener noreferrer" attribute.
• lynx is opened with the -noreferer option.

browse AsciiDoc

To browse items in AsciiDoc format, install asciidoctor.

Shortcut Alias: nb b

nb browse can also be used with the alias nb b:

# open the current notebook in the terminal web browser
nb b

# open the item with id 123 in the "example" notebook using the terminal web browser
nb b example:123

# open the notebook named "sample" in the GUI web browser
nb b sample: -g

For more information, see nb browse.

🌄 Images

nb can be used to view, organize, browse, reference, and work with images in terminals, web browsers, and GUI applications.

Image Items

Import images with nb import:

# import the image file "example.png" into the current notebook
nb import example.png

# import an image file from a URL into the current notebook
nb import https://raw.githubusercontent.com/xwmx/nb/master/docs/images/nb.png

# nb import "sample.jpg" into the "demo" folder in the "example" notebook
nb import sample.jpg example:demo/

Imported images are displayed with 🌄 indicators in lists:

❯ nb
home
----
[5] Example Five
[4] 🌄 example-image.png
[3] Example Three
[2] Example Two
[1] Example One

Imported image items can be opened in the system GUI application for the item's file type using nb open:

# open the image "example-image.png" in the system GUI photo viewer
nb open example-image.png

# open the image with id "4" in the system GUI photo viewer
nb 4 o

Image items can be viewed in web browsers with nb browse, providing a convenient mechanism for browsing notebooks and folders containing image collections.

nb browse renders image items within in an <img> tag on the item page. Open the item page for an image item by passing a selector to nb browse, optionally including the -g / --gui option to open the page in the system GUI web browser:

# open item with id "123" in the terminal web browser
nb browse 123

# open item with id "456" in the "example" notebook in the GUI web browser
nb browse example:456 --gui

# open item "example:456" in the GUI web browser, alternative
nb example:456 b -g

The original file can be viewed or downloaded from the item page by either clicking the image item or using the down arrow (↓) link.

nb browse --gui displays images in any GUI web browser. Some terminal web browsers, such as w3m, can be configured to display images.

nb show can display images directly in the terminal with supported tools and configurations, including:

• catimg
• Chafa
• ImageMagick with a terminal that supports sixels
• imgcat with iTerm2
• kitty's icat kitten
• termvisage
• timg
• viu

A preferred image viewer tool can be set with the $NB_IMAGE_TOOL variable in your ~/.nbrc file, which can be opened in your editor with nb settings edit.

Inline Images

Images can be referenced and rendered inline within notes, bookmarks, and other items.

To reference an image in the same notebook, specify the image's relative path within the notebook:

# reference "example.jpg" from markdown
![](example.jpg)

# reference "demo.png" in the "sample" folder from markdown
![](sample/demo.png)

Images in any notebook can be referenced using the --original URL, obtainable from the image's nb browse item page by either clicking the image item or using the down arrow (↓) link.

# reference "example.jpg" in the "home" notebook with the --original URL
![](http://localhost:6789/--original/home/example.jpg)

Image references in content are rendered inline within web browsers with nb browse and nb show --render.

<img> tags are stripped from bookmarked content when rendering to HTML. Inline images can still be used in other bookmark sections like ## Comment.

🗂 Zettelkasten

Zettelkasten (German: "slip box") is a method of note-taking and personal knowledge management modeled around a few key features:

• Notes are taken liberally on index cards.
• Each note is numbered for easy reference.
• Index cards are organized into boxes.
• Index cards can reference other index cards.
• Cards can include tags and other metadata.

Since nb works directly on plain text files organized in normal system directories in normal git repositories, nb is a very close digital analogue to physical zettelkasten note-taking.

For more information about Zettelkasten, see Wikipedia.

📂 Folders

Items can be organized in folders. To add a note to a folder, call nb add with the folder's relative path within the notebook followed by a slash:

# add a new note in the folder named "example"
nb add example/

# add a new note in the folder named "demo" in "example"
nb add example/demo/

nb automatically creates any intermediate folders as needed.

Folders can be created directly using nb add folder, nb folders add, and nb add --type folder:

# create a new folder named "sample"
nb add folder sample

# create a new folder named "sample", alternative
nb folders add sample

# create a new folder named "demo"
nb add demo --type folder

# create a folder named "example" containing a folder named "test"
nb add example/test --type folder

To list the items in a folder, pass the folder relative path to nb, nb ls, nb list, or nb browse with a trailing slash:

❯ nb example/demo/
home
----
[example/demo/3] Title Three
[example/demo/2] Title Two
[example/demo/1] Title One

Folders can also be identified by the folder's id and listed with a trailing slash:

❯ nb list
[1] 📂 example

❯ nb list 1/
[example/2] 📂 demo
[example/1] document.md

❯ nb list 1/2/
[example/demo/3] Title Three
[example/demo/2] Title Two
[example/demo/1] Title One

Items in folders can be idenitified with the folder's relative path using either folder ids or names, followed by the id, title, or filename of the item:

# list item 1 ("Title One", one.md) in the example/demo/ folder
nb list example/demo/1

# edit item 1 ("Title One", one.md) in the example/demo/ folder
nb edit example/2/one.md

# show item 1 ("Title One", one.md) in the example/demo/ folder
nb show 1/2/Title\ One

# delete item 1 ("Title One", one.md) in the example/demo/ folder
nb delete 1/demo/1

For folders and items in other notebooks, combine the relative path with the notebook name, separated by a colon:

# list the contents of the "sample" folder in the "example" notebook
nb example:sample/

# add an item to the "sample/demo" folder in the "example" notebook
nb add example:sample/demo/

# edit item 3 in the "sample/demo" folder in the "example" notebook
nb edit example:sample/demo/3

Browse starting at any folder with nb browse:

❯ nb browse example:sample/demo/
❯nb · example : sample / demo /

search: [                    ]

[example:sample/demo/5] Title Five
[example:sample/demo/4] Title Four
[example:sample/demo/3] Title Three
[example:sample/demo/2] Title Two
[example:sample/demo/1] Title One

For more information about identifying folders, see Selectors.

📌 Pinning

Items can be pinned so they appear first in nb, nb ls, and nb browse:

❯ nb
home
----
[2] 📌 Title Two
[5] Title Five
[4] Title Four
[3] Title Three
[1] Title One

Use nb pin and nb unpin to pin and unpin items:

❯ nb
home
----
[5] Title Five
[4] Title Four
[3] Title Three
[2] Title Two
[1] Title One

❯ nb pin 4
Pinned: [4] four.md "Title Four"

❯ nb pin 1
Pinned: [1] one.md "Title One"

❯ nb
home
----
[4] 📌 Title Four
[1] 📌 Title One
[5] Title Five
[3] Title Three
[2] Title Two

❯ nb unpin 4
Unpinned: [4] four.md "Title Four"

❯ nb
home
----
[1] 📌 Title One
[5] Title Five
[4] Title Four
[3] Title Three
[2] Title Two

nb can also be configured to pin notes that contain a specified #hashtag or other search pattern. To enable tag / search-based pinning, set the $NB_PINNED_PATTERN environment variable to the desired #tag or pattern.

For example, to treat all items tagged with #pinned as pinned items, add the following line to your ~/.nbrc file, which can be opened in your editor with nb settings edit:

export NB_PINNED_PATTERN="#pinned"

All indicator icons in nb can be customized, so to use a different character as the pindicator, simply add a line like the following to your ~/.nbrc file:

export NB_INDICATOR_PINNED="💖"

❯ nb
home
----
[1] 💖 Title One
[5] Title Five
[4] Title Four
[3] Title Three
[2] Title Two

To bump an item to the top of the list without pinning, use the bump plugin.

🔍 Search

Use nb search (shortcut: nb q) to perform full text searches, with support for regular expressions, #tags, and AND, OR, and NOT queries:

# search current notebook for "example query"
nb search "example query"

# search the notebook "example" for "example query"
nb search example: "example query"

# search the folder named "demo" for "example query"
nb search demo/ "example query"

# search all unarchived notebooks for "example query" and list matching items
nb search "example query" --all --list

# search for "example" AND "demo" with multiple arguments
nb search "example" "demo"

# search for "example" AND "demo" with option
nb search "example" --and "demo"

# search for "example" OR "sample" with argument
nb search "example|sample"

# search for "example" OR "sample" with option
nb search "example" --or "sample"

# search for items matching both "Example" AND "Sample", and NOT "Demo"
nb search "Example" --and "Sample" --not "Demo"

# search items containing the hashtag "#example"
nb search "#example"

# search with a regular expression
nb search "\d\d\d-\d\d\d\d"

# search bookmarks for "example"
nb search "example" --type bookmark

# search bookmarks for "example", alternative
nb bk q "example"

# search the current notebook for "example query"
nb q "example query"

# search the notebook named "example" for "example query"
nb q example: "example query"

# search all unarchived notebooks for "example query" and list matching items
nb q -la "example query"

nb search prints the id number, filename, and title of each matched file, followed by each search query match and its line number, with color highlighting:

❯ nb search "example"
[314]  🔖 example.bookmark.md "Example Bookmark (example.com)"
--------------------------------------------------------------
1:# Example Bookmark (example.com)

3:<https://example.com>

[2718] example.md "Example Note"
--------------------------------
1:# Example Note

To just print the note information line without the content matches, use the -l or --list option:

❯ nb search "example" --list
[314]  🔖 example.bookmark.md "Example Bookmark (example.com)"
[2718] example.md "Example Note"

Multiple query arguments are treated as AND queries, returning items that match all queries. AND queries can also be specified with the --and <query> option:

# search for items tagged with "#example" AND "#demo" AND "#sample" using
# multiple arguments
nb q "#example" "#demo" "#sample"

# options
nb q "#example" --and "#demo" --and "#sample"

nb matches AND query terms regardless of where they appear in a document, an improvement over most approaches for performing AND queries with command line tools, which typically only match terms appearing on the same line.

OR queries return items that match at least one of the queries and can be created by separating terms in a single argument with a pipe character | or with the --or <query> option:

# search for "example" OR "sample" with argument
nb q "example|sample"

# search for "example" OR "sample" with option
nb q "example" --or "sample"

--or and --and queries can be used together:

nb q "example" --or "sample" --and "demo"
# equivalent: example|sample AND demo|sample

NOT queries exclude items that match the specified query and are specified with --not <query>, which can be used with --and and --or:

# search for items that match "Example", excluding items that also match "Sample"
nb search "Example" --not "Sample"

# search for items matching both "Example" AND "Sample", and NOT "Demo"
nb search "Example" --and "Sample" --not "Demo"

Search for #tags with flexible nb search --tags [<tags>] / nb q -t [<tags>] options:

# search for tags in the current notebook
nb search --tags

# search for tags in the "sample" notebook, shortcut alias
nb sample:q --tags

# search for items tagged with "#tag1"
nb search --tag tag1

# search for items tagged with "#tag1", shortcut alias and short option
nb q -t tag1

# search for items tagged with "#tag1", shortcut alias and argument
nb q \#tag1

# search for items tagged with "#tag1", shortcut alias and argument, alternative
nb q "#tag1"

# search for items in the "sample" notebook tagged with "#tag1" AND "#tag2"
nb sample:search --tag tag1 --tag tag2

# search for items in the "sample" notebook tagged with "#tag1" AND "#tag2"
nb sample:q --tags tag1,tag2

# search for items in the current notebook tagged with "#tag1" AND "#tag2"
nb q --tag tag1 --tag tag2

# search for items in the current notebook tagged with "#tag1" OR "#tag2"
nb q -t tag1 --or -t tag2

# search for items tagged with "#tag1" AND "#tag2" AND "#tag3"
nb q -t tag1 --tags tag2,tag3

# search for items tagged with "#tag1" OR "#tag2" OR "#tag3"
nb q -t tag1 --or --tags tag2,tag3

# search for items tagged with "#tag1" OR "#tag2" OR "#tag3"
nb q \#tag1 --or -t tag2 --or "#tag3"

nb search leverages Git's powerful built-in git grep. nb also supports performing searches with alternative search tools using the --utility <name> option.

Supported alternative search tools:

• rga
• rg
• ag
• ack
• grep

Shortcut Alias: nb q

nb search can also be used with the alias nb q (for "query"):

# search for "example" and print matching excerpts
nb q "example"

# search for "example" and list each matching file
nb q -l "example"

# search for "example" in all unarchived notebooks
nb q -a "example"

# search for "example" in the notbook named "sample"
nb sample:q "example"

For more information about search, see nb help search.

Searching with browse

Searches can be performed within terminal and GUI web browsers using nb browse --query / nb b -q:

❯ nb browse --query "#example"
❯nb · home : +

search: [#example             ]

[home:7]   Title Seven
[home:32]  Title Thirty-Two
[home:56]  Title Fifty-Six
[home:135] Title One Hundred and Thirty-Five

For more information, see Browsing.

↔ Moving & Renaming

Use nb move (alias: nb rename, shortcut: nb mv) to move and rename items:

# move "example.md" to "sample.org"
nb move example.md sample.org

# rename note 2 ("example.md") to "New Name.md"
nb rename 2 "New Name"

Items can be moved between notebooks and folders:

# move note 12 from the "example" notebook into "Sample Folder" in the "demo" notebook
nb move example:12 demo:Sample\ Folder/

When the file extension is omitted, the existing extension is used:

# rename "example.bookmark.md" to "New Name.bookmark.md"
nb move example.bookmark.md "New Name"

When only a file extension is specified, only the extension is updated:

# change the file extension of note 5 ("demo file.md") to .org ("demo file.org")
nb rename 5 .org

Use nb rename --to-bookmark to change the extension of a note to .bookmark.md, nb rename --to-todo to change the extension to .todo.md, and nb rename --to-note to change the extension of a bookmark or todo to either .md or the extension set with nb set default_extension:

# rename note 3 ("example.md") to a bookmark named "example.bookmark.md"
nb rename 3 --to-bookmark

# rename bookmark 6 ("sample.bookmark.md") to a note named "sample.md"
nb rename 6 --to-note

# rename note 7 ("demo.md") to a todo named "demo.todo.md"
nb rename 7 --to-todo

Use nb rename --to-title to set the filename to the note title, lowercased with spaces and disallowed filename characters replaced with underscores:

❯ nb rename 12 --to-title
Moving:   [12] 20210101010000.md "Example Title"
To:       example_title.md
Proceed?  [y/N]

Copy an item to a destination notebook, folder path, or filename with nb copy (alias: nb duplicate):

# copy item 456 to "sample.md"
nb copy 456 sample.md

# copy item 678 to the "example" notebook
nb copy 678 example:

# copy item 789 to the "demo" folder
nb copy 789 demo/

# copy item 543 to test.md in the "sample" folder in the "example" notebook
nb copy 543 example:sample/test.md

Omit a destination to copy the item in place:

# copy item 123 ("example.md") to example-1.md
❯ nb copy 123
Added: [124] example-1.md

# copy item 123 ("example.md") to example-2.md, alias
❯ nb duplicate 123
Added: [125] example-2.md

For more information about moving, renaming, and copying items, see nb help move and nb help copy.

🗒 Revision History

Whenever a note is added, modified, or deleted, nb automatically commits the change to git transparently in the background.

Use nb history to view the revision history of any notebook, folder, or item:

# show history for current notebook
nb history

# show history for note number 4
nb history 4

# show history for note with filename example.md
nb history example.md

# show history for note titled "Example"
nb history Example

# show history for the notebook named "example"
nb example:history

# show history for the notebook named "example", alternative
nb history example:

# show the history for note 12 in the notebook named "example"
nb history example:12

nb history uses git log by default and prefers tig when available.

Authorship

By default, git commits are attributed to the email and name configured in your global git configuration.

Change the email and name used for a notebook with nb notebooks author:

# edit the commit author email and name for the current notebook
❯ nb notebooks author
Current configuration for: home
--------------------------
email (global): example@example.test
name  (global): Example Name

Update?  [y/N]

# edit the commit author email and name for the notebook named "example"
❯ nb notebooks author example
Current configuration for: example
--------------------------
email (global): example@example.test
name  (global): Example Name

Update?  [y/N]

The updated author email and name applies to subsequent commits.

To use a different email and name from the beginning of a notebook's history, create the new notebook using nb notebooks add --author or nb notebooks init --author.

📚 Notebooks

You can create additional notebooks, each of which has its own version history.

Create a new notebook with nb notebooks add:

# add a notebook named example
nb notebooks add example

nb and nb ls list the available notebooks above the list of notes:

❯ nb
example · home
--------------
[3] Title Three
[2] Title Two
[1] Title One

Commands in nb run within the current notebook, and identifiers such as ids, filenames, and titles refer to notes within the current notebook. nb edit 3, for example, tells nb to edit note with id 3 within the current notebook.

To switch to a different notebook, use nb use:

# switch to the notebook named "example"
nb use example

If you are in one notebook and you want to perform a command in a different notebook without switching to it, add the notebook name with a colon before the command name:

# add a new note in the notebook "example"
nb example:add

# add a new note in the notebook "example", shortcut alias
nb example:a

# show note 5 in the notebook "example"
nb example:show 5

# show note 5 in the notebook "example", shortcut alias
nb example:s 5

# edit note 12 in the notebook "example"
nb example:edit 12

# edit note 12 in the notebook "example", shortcut alias
nb example:e 12

# search for "example query" in the notebook "example"
nb example:search "example query"

# search for "example query" in the notebook "example", shortcut alias
nb example:q "example query"

# show the revision history of the notebook "example"
nb example:history

The notebook name with colon can also be used as a modifier to the id, filename, or title:

# edit note 12 in the notebook "example"
nb edit example:12

# edit note 12 in the notebook "example", shortcut alias
nb e example:12

# edit note 12 in the notebook "example", alternative
nb example:12 edit

# edit note 12 in the notebook "example", alternative, shortcut alias
nb example:12 e

# show note titled "misc" in the notebook "example"
nb show example:misc

# show note titled "misc" in the notebook "example", shortcut alias
nb s example:misc

# delete note with filename "todos.md" in the notebook "example", alternative
nb example:todos.md delete

# delete note with filename "todos.md" in the notebook "example", alternative,
# shortcut alias
nb example:todos.md d

When a notebook name with colon is called without a subcommand, nb runs nb ls in the specified notebook:

❯ nb example:
example · home
--------------
[example:3] Title Three
[example:2] Title Two
[example:1] Title One

A bookmark can be created in another notebook by specifying the notebook name with colon, then a space, then the URL and bookmark options:

# create a new bookmark in a notebook named "sample"
❯ nb sample: https://example.com --tags tag1,tag2

Notes can also be moved between notebooks:

# move note 3 from the current notebook to "example"
nb move 3 example:

# move note 5 in the notebook "example" to the notebook "sample"
nb move example:5 sample:

Example Workflow

The flexibility of nb's argument handling makes it easy to build commands step by step as items are listed, filtered, viewed, and edited, particularly in combination with shell history:

# list items in the "example" notebook
❯ nb example:
example · home
--------------
[example:3] Title Three
[example:2] Title Two
[example:1] Title One

# filter list
❯ nb example: three
[example:3] Title Three

# view item
❯ nb example:3 show
# opens item in `less`

# edit item
❯ nb example:3 edit
# opens item in $EDITOR

Notebooks and Tab Completion

nb tab completion is optimized for frequently running commands in various notebooks using the colon syntax, so installing the completion scripts is recommended and makes working with notebooks easy, fluid, and fun.

For example, listing the contents of a notebook is usually as simple as typing the first two or three characters of the name, then pressing the <tab> key, then pressing <enter> / <return>:

❯ nb exa<tab>
# completes to "example:"
❯ nb example:
example · home
--------------
[example:3] Title Three
[example:2] Title Two
[example:1] Title One

Scoped notebook commands are also available in tab completion:

❯ nb exa<tab>
# completes to "example:"
❯ nb example:hi<tab>
# completes to "example:history"

Notebooks, Tags, and Taxonomy

nb is optimized to work well with a collection of notebooks, so notebooks are a good way to organize notes and bookmarks by top-level topic.

#tags are searchable across notebooks and can be created ad hoc, making notebooks and tags distinct and complementary organizational systems in nb.

Search for a tag in or across notebooks with nb search / nb q:

# search for #tag in the current notebook
nb q --tag tag

# search for #tag in all notebooks, short options
nb q -t tag -a

# search for #tag in the "example" notebook, argument
nb q example: "#tag"

Global and Local Notebooks

Global Notebooks

By default, all nb notebooks are global, making them always accessible in the terminal regardless of the current working directory. Global notebooks are stored in the directory configured in nb set nb_dir, which is ~/.nb by default.

Local Notebooks

nb also supports creating and working with local notebooks. Local notebooks are notebooks that are anywhere on the system outside of $NB_DIR. Any folder can be an nb local notebook, which is just a normal folder that has been initialized as a git repository and contains an nb .index file. Initializing a folder as an nb local notebook is a very easy way to add structured git versioning to any folder of documents and other files.

When nb runs within a local notebook, the local notebook is set as the current notebook:

❯ nb
local · example · home
----------------------
[3] Title Three
[2] Title Two
[1] Title One

A local notebook is always referred to by the name local and otherwise behaves just like a global notebook whenever a command is run from within it:

# add a new note in the local notebook
nb add

# edit note 15 in the local notebook
nb edit 15

# move note titled "Todos" from the home notebook to the local notebook
nb move home:Todos local:

# move note 1 from the local notebook to the home notebook
nb move 1 home:

# search the local notebook for <query string>
nb search "query string"

# search the local notebook and all unarchived global notebooks for <query string>
nb search "query string" --all

Local notebooks can be created with nb notebooks init:

# initialize the current directory as a notebook
nb notebooks init

# create a new notebook at ~/example
nb notebooks init ~/example

# clone an existing notebook to ~/example
nb notebooks init ~/example https://github.com/example/example.git

Local notebooks can also be created by exporting a global notebook:

# export global notebook named "example" to "../path/to/destination"
nb notebooks export example ../path/to/destination

# alternative
nb export example ../path/to/destination

Local notebooks can also be imported, making them global:

# import notebook or folder at "../path/to/notebook"
nb notebooks import ../path/to/notebook

# alternative
nb import ../path/to/notebook

nb notebooks init and nb notebooks import can be used together to easily turn any directory of existing files into a global nb notebook:

❯ ls
example-directory

❯ nb notebooks init example-directory
Initialized local notebook: /home/username/example-directory

❯ nb notebooks import example-directory
Imported notebook: example-directory

❯ nb notebooks
example-directory
home

Archiving Notebooks

Notebooks can be archived using nb archive (shortcut: nb ar):

# archive the current notebook
nb archive

# archive the notebook named "example"
nb archive example

# archive the current notebook, shortcut alias
nb ar

# archive the notebook named "example", shortcut alias
nb ar example

When a notebook is archived it is not included in nb / nb ls output, nb search --all, or tab completion, nor synced automatically with nb sync --all.

❯ nb
example1 · example2 · example3 · [1 archived]
---------------------------------------------
[3] Title Three
[2] Title Two
[1] Title One

Archived notebooks can still be used individually using normal notebook commands:

# switch the current notebook to the archived notebook "example"
nb use example

# run the `list` subcommand in the archived notebook "example"
nb example:list

Check a notebook's archival status with nb status (shortcut: nb st) and nb notebooks status:

# print status information, including archival status, for the current notebook
nb status

# print status information, including archival status, for the notebook named "example"
nb status example

# print status information, including archival status, for the current notebook,
# shortcut alias
nb st

# print status information, including archival status, for the notebook named "example",
# shortcut alias
nb st example

# print the archival status of the current notebook
nb notebooks status

# print the archival status of the notebook named "example"
nb notebooks status example

Use nb unarchive (shortcut: nb unar) to unarchive a notebook:

# unarchive the current notebook
nb unarchive

# unarchive the notebook named "example"
nb unarchive example

For more information about working with notebooks, see nb help notebooks, nb help archive, and nb help unarchive.

For technical details about notebooks, see nb Notebook Specification.

🔄 Git Sync

Each notebook can be synced with a remote git repository by setting the remote URL using nb remote:

# set the current notebook's remote to a private GitHub repository
nb remote set https://github.com/example/example

# set the remote for the notebook named "example"
nb example:remote set https://github.com/example/example

Any notebook with a remote URL will sync automatically every time a command is run in that notebook.

When you use nb on multiple systems, you can set a notebook on each system to the same remote and nb will keep everything in sync in the background every time there's a change in that notebook.

Since each notebook has its own git history, you can have some notebooks syncing with remotes while other notebooks are only available locally on that system.

Many services provide free private git repositories, so git syncing with nb is easy, free, and vendor-independent. You can also sync your notes using Dropbox, Drive, Box, Syncthing, or another syncing tool by changing your nb directory with nb set nb_dir <path>, and git syncing will still work simultaneously.

Clone an existing notebook by passing the URL to nb notebooks add:

# create a new notebook named "example" cloned from a private GitLab repository
nb notebooks add example https://gitlab.com/example/example.git

Turn off syncing for a notebook by removing the remote:

# remove the remote from the current notebook
nb remote remove

# remove the remote from the notebook named "example"
nb example:remote remove

Automatic git syncing can be turned on or off with nb set auto_sync.

To sync manually, use nb sync:

# manually sync the current notebook
nb sync

# manually sync the notebook named "example"
nb example:sync

To bypass nb syncing and run git commands directly within a notebook, use nb git:

# run `git fetch` in the current notebook
nb git fetch origin

# run `git status` in the notebook named "example"
nb example:git status

Syncing Multiple Notebooks with One Remote

Multiple notebooks can be synced to one remote using orphan branches. An orphan branch is a branch with a history that is independent from the repository's main, master, or equivalent primary branch history. To sync a notebook with a new orphan branch, add the remote using nb remote set and select the option to create a new orphan branch. The name of orphan branch is derived from notebook name and can alternatively be specified as an argument to nb remote set:

# set the remote for the current notebook to a remote URL and branch
nb remote set https://github.com/xwmx/example demo-branch

To create a notebook using an existing orphan branch on a remote, pass the branch name to nb init, nb notebooks add, or nb notebooks init after the URL:

# initialize new "home" notebook with the branch "sample-branch" on the remote
nb init https://github.com/xwmx/example sample-branch

# add a new "example" notebook from the branch "example-branch" on the remote
nb notebooks add example https://github.com/xwmx/example example-branch

To list all branches on a remote, use nb remote branches:

# list all branches on the current remote
nb remote branches

# list all branches on a remote repository identified by a URL
nb remote branches "https://github.com/xwmx/example"

For information about assigning remotes, see nb help remote.

Private Repositories and Git Credentials

Syncing with private repositories requires configuring git to not prompt for credentials. For repositories cloned over HTTPS, credentials can be cached with git . For repositories cloned over SSH, keys can be added to the ssh-agent .

Use nb sync within a notebook to determine whether your configuration is working. If nb sync displays a password prompt, then follow the instructions above to configure your credentials. The password prompt can be used to authenticate, but nb does not cache or otherwise handle git credentials in any way, so there will likely be multiple password prompts during each sync if credentials are not configured.

Sync Conflict Resolution

nb handles git operations automatically, so you shouldn't ever need to use the git command line tool directly. nb merges changes when syncing and handles conflicts using a couple different strategies.

When nb sync encounters a conflict in a text file and can't cleanly merge overlapping local and remote changes, nb saves both versions within the file separated by git conflict markers and prints a message indicating which files contain conflicting text. Use nb edit to remove the conflict markers and delete any unwanted text.

For example, in the following file, the second list item was changed on two systems, and git has no way to determine which one we want to keep:

# Example Title

- List Item apple
<<<<<<< HEAD
- List Item apricot
=======
- List Item pluot
>>>>>>> 719od01... [nb] Commit
- List Item plum

The local change is between the lines starting with <<<<<<< and =======, while the remote change is between the ======= and >>>>>>> lines.

To resolve this conflict by keeping both items, simply edit the file with nb edit and remove the lines starting with <<<<<<<, =======, and >>>>>>>:

# Example Title

- List Item apple
- List Item apricot
- List Item pluot
- List Item plum

When nb encounters a conflict in a binary file, such as an encrypted note, both versions of the file are saved in the notebook as individual files, with --conflicted-copy appended to the filename of the version from the remote. To resolve a conflicted copy of a binary file, compare both versions and merge them manually, then delete the --conflicted-copy.

If you do encounter a conflict that nb says it can't merge at all, nb git and nb run can be used to perform git and shell operations within the notebook to resolve the conflict manually. Please also open an issue with any relevant details that could inform a strategy for handling any such cases automatically.

↕️ Import / Export

Files of any type can be imported into a notebook using nb import (shortcut: nb i). nb edit and nb open open files in your system's default application for that file type.

# import an image file
nb import ~/Pictures/example.png

# open image in your default image viewer
nb open example.png

# import a .docx file
nb import ~/Documents/example.docx

# open .docx file in Word or your system's .docx viewer
nb open example.docx

Multiple filenames and globbing are supported:

# import all files and directories in the current directory
nb import ./*

# import all markdown files in the current directory
nb import ./*.md

# import example.md and sample.md in the current directory
nb import example.md sample.md

nb import can also download and import files directly from the web:

# import a PDF file from the web
nb import https://example.com/example.pdf
# Imported "https://example.com/example.pdf" to "example.pdf"

# open example.pdf in your system's PDF viewer
nb open example.pdf

Some imported file types have indicators to make them easier to identify in lists:

❯ nb
home
----
[6] 📖 example-ebook.epub
[5] 🌄 example-picture.png
[4] 📄 example-document.docx
[3] 📹 example-video.mp4
[2] 🔉 example-audio.mp3
[1] 📂 Example Folder

Notes, bookmarks, and other files can be exported using nb export. If Pandoc is installed, notes can be automatically converted to any of the formats supported by Pandoc. By default, the output format is determined by the file extension:

# export a Markdown note to a .docx Microsoft Office Word document
nb export example.md /path/to/example.docx

# export a note titled "Movies" to an HTML web page.
nb export Movies /path/to/example.html

For more control over the pandoc options, use the nb export pandoc subcommand:

# export note 42 as an epub with pandoc options
nb export pandoc 42 --from markdown_strict --to epub -o path/to/example.epub

nb export notebook and nb import notebook can be used to export and import notebooks:

# export global notebook named "example" to "../path/to/destination"
nb export notebook example ../path/to/destination

# import notebook or folder at "../path/to/notebook"
nb import notebook ../path/to/notebook

nb export notebook and nb import notebook behave like aliases for nb notebooks export and nb notebooks import, and the subcommands can be used interchangeably.

For more information about imported and exported notebooks, see Global and Local Notebooks.

For nb import and nb export help information, see nb help import and nb help export.

Exporting with browse

Items can be exported using terminal and GUI web browsers. Use the down arrow (↓) link on the nb browse item page to download the original file:

❯ nb browse 123
❯nb · home : 123 · ↓ | +

    example.pdf
 

⚙️ set & settings

nb set and nb settings open the settings prompt, which provides an easy way to change your nb settings.

nb set

To update a setting in the prompt, enter the setting name or number and then enter the new value. nb will add the setting to your ~/.nbrc configuration file.

Example: editor

nb can be configured to use a specific command line editor using the editor setting.

The settings prompt for a setting can be started by passing the setting name or number to nb set:

❯ nb set editor
[6]  editor
     ------
     The command line text editor used by `nb`.

     • Example Values:

         atom
         code
         emacs
         hx
         macdown
         mate
         micro
         nano
         pico
         subl
         vi
         vim

EDITOR is currently set to vim

Enter a new value, unset to set to the default value, or q to quit.
Value:

A setting can also be updated without the prompt by passing both the name and value to nb set:

# set editor with setting name
❯ nb set editor code
EDITOR set to code

# set editor with setting number (6)
❯ nb set 6 code
EDITOR set to code

# set the color theme to blacklight
❯ nb set color_theme blacklight
NB_COLOR_THEME set to blacklight

# set the default `ls` limit to 10
❯ nb set limit 10
NB_LIMIT set to 10

Use nb settings get to print the value of a setting:

❯ nb settings get editor
code

❯ nb settings get 6
code

Use nb unset or nb settings unset to unset a setting and revert to the default:

❯ nb unset editor
EDITOR restored to the default: vim

❯ nb settings get editor
vim

nb set and nb settings are aliases that refer to the same subcommand, so the two subcommand names can be used interchangeably.

For more information about set and settings, see nb help settings.

🎨 Color Themes

nb uses color to highlight various interface elements, including ids and selectors, the current notebook name, the shell prompt, divider lines, syntax elements, and links.

nb includes several built-in color themes and also supports user-defined themes. The current color theme can be set using nb set color_theme:

nb set color_theme

Built-in Color Themes

console

desert

electro

Custom Color Themes

Color themes are nb plugins with a .nb-theme file extension. .nb-theme files are expected to contain one if statement testing for the theme name and setting the color environment variables to tput ANSI color numbers:

# turquoise.nb-theme
if [[ "${NB_COLOR_THEME}" == "turquoise" ]]
then
  export NB_COLOR_PRIMARY=43
  export NB_COLOR_SECONDARY=38
fi

View this theme as a complete file: plugins/turquoise.nb-theme

Themes can be installed using nb plugins:

❯ nb plugins install https://github.com/xwmx/nb/blob/master/plugins/turquoise.nb-theme
Plugin installed:
/home/example/.nb/.plugins/turquoise.nb-theme

Once a theme is installed, use nb set color_theme to set it as the current theme:

❯ nb set color_theme turquoise
NB_COLOR_THEME set to turquoise

The primary and secondary colors can also be overridden individually, making color themes easily customizable:

# open the settings prompt for the primary color
nb set color_primary

# open the settings prompt for the secondary color
nb set color_secondary

To view a table of available colors and numbers, run:

nb set colors

Terminal Syntax Highlighting Theme

nb displays files with syntax highlighting when bat, highlight, or Pygments is installed.

When bat is installed, syntax highlighting color themes are available for both light and dark terminal backgrounds. To view a list of available themes and set the syntax highlighting color theme, use nb set syntax_theme.

GUI Web Syntax Highlighting

Syntax highlighting is also available when viewing and editing items in text formats with nb browse --gui, which incorporates the color theme's primary color into the syntax theme:

Indicators

nb uses emoji characters to represent information about files in lists. These characters are referred to internally as "indicators" and can be customized by assigning a different character to the indicator's environment variable in your ~/.nbrc file, which can be opened with nb settings edit.

For example, to use a different indicator for pinned items, add a line like the following to your ~/.nbrc file:

export NB_INDICATOR_PINNED="✨"

To turn off an indicator, assign the variable to an empty string:

export NB_INDICATOR_PINNED=""

Available indicator variables with default values:

export  NB_INDICATOR_AUDIO="🔉"
export  NB_INDICATOR_BOOKMARK="🔖"
export  NB_INDICATOR_DOCUMENT="📄"
export  NB_INDICATOR_EBOOK="📖"
export  NB_INDICATOR_ENCRYPTED="🔒"
export  NB_INDICATOR_FOLDER="📂"
export  NB_INDICATOR_IMAGE="🌄"
export  NB_INDICATOR_PINNED="📌"
export  NB_INDICATOR_TODO="✔️ "
export  NB_INDICATOR_TODO_DONE="✅"
export  NB_INDICATOR_VIDEO="📹"

$ Shell Theme Support

• astral Zsh Theme - Displays the current notebook name in the context line of the prompt.

🔌 Plugins

nb includes support for plugins, which can be used to create new subcommands, design themes, and otherwise extend the functionality of nb.

nb supports two types of plugins, identified by their file extensions:

Plugins are managed with the nb plugins subcommand and are installed in the ${NB_DIR}/.plugins directory.

Plugins can be installed from either a URL or a path using the nb plugins install subcommand.

# install a plugin from a URL
nb plugins install https://raw.githubusercontent.com/xwmx/nb/master/plugins/clip.nb-plugin

# install a plugin from a standard GitHub URL
nb plugins install https://github.com/xwmx/nb/blob/master/plugins/example.nb-plugin

# install a theme from a standard GitHub URL
nb plugins install https://github.com/xwmx/nb/blob/master/plugins/turquoise.nb-theme

# install a plugin from a path
nb plugins install plugins/example.nb-plugin

The <url> should be the full URL to the plugin file. nb also recognizes regular GitHub URLs, which can be used interchangeably with raw GitHub URLs.

Installed plugins can be listed with nb plugins, which optionally takes a name and prints full paths:

❯ nb plugins
clip.nb-plugin
example.nb-plugin
turquoise.nb-theme

❯ nb plugins clip.nb-plugin
clip.nb-plugin

❯ nb plugins --paths
/home/example/.nb/.plugins/clip.nb-plugin
/home/example/.nb/.plugins/example.nb-plugin
/home/example/.nb/.plugins/turquoise.nb-theme

❯ nb plugins turquoise.nb-theme --paths
/home/example/.nb/.plugins/turquoise.nb-theme

Use nb plugins uninstall to uninstall a plugin:

❯ nb plugins uninstall example.nb-plugin
Plugin successfully uninstalled:
/home/example/.nb/.plugins/example.nb-plugin

Creating Plugins

Plugins are written in a Bash-compatible shell scripting language and have an .nb-plugin extension.

nb includes a few example plugins:

• example.nb-plugin
• clip.nb-plugin
• ebook.nb-plugin

Create a new subcommand in three easy steps:

1. Add the new subcommand name with _subcommands add <name>:

_subcommands add "example"

2. Define help and usage text with _subcommands describe <subcommand> <usage>:

_subcommands describe "example" <<HEREDOC
Usage:
  nb example

Description:
  Print "Hello, World!"
HEREDOC

3. Define the subcommand as a function, named with a leading underscore:

_example() {
  printf "Hello, World!\\n"
}

That's it! 🎉

View the complete plugin: plugins/example.nb-plugin

With example.nb-plugin installed, nb includes an nb example subcommand that prints "Hello, World!"

For a full example, clip.nb-plugin add clipboard functionality to nb and demonstrates how to create a plugin using nb subcommands and simple shell scripting.

You can install any plugin you create locally with nb plugins install <path>, and you can publish it on GitHub, GitLab, or anywhere else online and install it with nb plugins install <url>.

API

The nb API is the command line interface, which is designed for composability and provides a variety of powerful options for interacting with notes, bookmarks, notebooks, and nb functionality. Within plugins, subcommands can be called using their function names, which are named with leading underscores. Options can be used to output information in formats suitable for parsing and processing:

# print the content of note 3 to standard output with no color
_show 3 --print --no-color

# list all unarchived global notebook names
_notebooks --names --no-color --unarchived --global

# list all filenames in the current notebook
_list --filenames --no-id --no-indicator

# print the path to the current notebook
_notebooks current --path

nb automatically scans arguments for selectors with notebook names and updates the current notebook if a valid one is found.

Identifier selectors are passed to subcommands as arguments along with any subcommand options. Use show <selector> to query information about the file specified in the selector. For example, to obtain the filename of a selector-specified file, use show <selector> --filename:

_example() {
  local _selector="${1:-}"
  [[ -z "${_selector:-}" ]] && printf "Usage: example <selector>\\n" && exit 1

  # Get the filename using the selector.
  local _filename=
  _filename="$(_show "${_selector}" --filename)"

  # Rest of subcommand function...
}

notebooks current --path returns the path to the current notebook:

# _example() continued:

# get the notebook path
local _notebook_path=
_notebook_path="$(_notebooks current --path)"

# print the file at "${_notebook_path}/${_filename}" to standard output
cat "${_notebook_path}/${_filename}"

See clip.nb-plugin for a practical example using both show <selector> and notebooks current --path along with other subcommands called using their underscore-prefixed function names.

:/ Selectors

Items in nb are primarily identified using structured arguments called "selectors." Selectors are like addresses for notebooks, folders, and items. A selector can be as simple as an id like 123 or folder path like example/, or it can combine multiple elements to identify an item in a nested folder within a particular notebook, such as:

cli:tools/shellcheck/home-page.bookmark.md

An item, folder, or notebook selector is constructed by specifying the notebook name, folder path, and / or item identifier in the following pattern:

notebook:folder/path/item-idenitifer

Represented in a docopt-like format:

[<notebook>:][<folder-path>/][<id> | <filename> | <title>]

Notebooks are identified by the notebook name followed by a colon. Folder and item identifiers without a notebook name refer to items within the current notebook. When a selector consists of notebook name and colon with no folder path or item identifier, the command runs in the root folder of the notebook:

# list items in the "example" notebook
nb example:

# add a new note named "Example Title" to the "example" notebook
nb add example: --title "Example Title"

# edit item with id "123" in the notebook "example"
nb edit example:123

A notebook selector can be combined with a subcommand name to run the command within the notebook:

# list all items in the "example" notebook and display excerpts
nb example:list -e

# edit item with id "123" in the "example" notebook
nb example:edit 123

# show the git history for the notebook named "example"
nb example:history

Folders are identified by relative path from the notebook root. Folders can be referenced by either id or name, and segments in nested paths can mix and match names and ids:

# list items in the folder named "sample" in the folder named demo"
nb sample/demo/

# add a new item to the folder named "demo" in the folder with id "3"
nb add 3/demo/

# show the history of the folder with id "4" in the folder named
# "sample" in the notebook named "example"
nb history example:sample/4/

A trailing slash indicates that the command is expected to operate on the contents of the folder. When a trailing slash is omitted, the selector refers to the folder itself:

❯ nb list sample
[1] 📂 sample

❯ nb list sample/
[sample/3] Title Three
[sample/2] Title Two
[sample/1] Title One

For more information about folders, see Folders.

An item is identified by id, filename, or title, optionally preceded by notebook name or folder path:

# edit item with id "123"
nb edit 123

# open the item titled "demo title" in the folder with id "3"
nb open 3/demo\ title

# show "file.md" in the "sample" folder in the "example" notebook
nb show example:sample/file.md

Items can also be specified using the full path:

# edit "demo.md" in the "sample" folder in the "home" notebook
nb edit /home/example/.nb/home/sample/demo.md

01 Metadata

Metadata in nb is primarily derived from git, the filesystem, and file content. For example, displayed timestamps are derived from git log, with nb show --added displaying the datetime of the first commit containing the file and nb show --updated displaying the datetime of the last commit in which the file was modified. Meanwhile, the file system's modified timestamp is used for sorting.

nb also uses plain text files to store ids and state information in git, including .index files, .pindex files, and .archived files.

Front Matter

User-defined metadata can be added to notes in nb using front matter. Front matter is a simple, human accessible, and future-friendly method for defining metadata fields in plain text and is well supported in tools for working with Markdown.

Front matter is defined within a Markdown file with triple-dashed lines (---) indicating the start and end of the block, with each field represented by a key name with a colon followed by the value:

---
title:  Example Title
author: xwmx
year:   2021
---

Example content.

More example content:

- one
- two
- three

Any metadata can be placed in the front matter block. nb uses the title: field for listing, filtering, and selecting items, if one is present, and ignores any other fields.

The simple key: value syntax is suitable for many metadata fields. More complex data can be defined using additional YAML capabilities.

❯ Interactive Shell

nb has an interactive shell that can be started with nb shell, nb -i, or nb --interactive:

$ nb shell
__          _
\ \   _ __ | |__
 \ \ | '_ \| '_ \
 / / | | | | |_) |
/_/  |_| |_|_.__/
------------------
nb shell started. Enter ls to list notes and notebooks.
Enter help for usage information. Enter exit to exit.
nb❯ ls
home
----
[3] Example
[2] Sample
[1] Demo

nb❯ edit 3 --content "New content."
Updated: [3] Example

nb❯ bookmark https://example.com
Added: [4] 🔖 example.bookmark.md "Example Title (example.com)"

nb❯ ls
home
----
[4] 🔖 Example Title (example.com)
[3] Example
[2] Sample
[1] Demo

nb❯ bookmark url 4
https://example.com

nb❯ search "example"
[4] example.bookmark.md "Example (example.com)"
-----------------------------------------------
1:# Example (example.com)

3:<https://example.com>

[3] example.md "Example"
------------------------
1:# Example

nb❯ exit
$

The nb shell recognizes all nb subcommands and options, providing a streamlined, distraction-free approach for working with nb.

Shortcut Aliases

Several core nb subcommands have shortcut aliases to make them faster to work with:

# `a` (add): add a new note named "example.md"
nb a example.md

# `+` (add): add a new note titled "Example Title"
nb + --title "Example Title"

# `b` (browse): open the folder named "sample" in the web browser
nb b sample/

# `o` (open): open the URL from bookmark 12 in your web browser
nb o 12

# `p` (peek): open the URL from bookmark 6 in your terminal browser
nb p 6

# `e` (edit): edit note 5
nb e 5

# `d` (delete): delete note 19
nb d 19

# `d` (delete): delete note 123 in the notebook named "example:"
nb - example:123

# `s` (show): show note 27
nb s 27

# `q` (search): search notes for "example query"
nb q "example query"

# `h` (help): display the help information for the `add` subcommand
nb h add

# `u` (use): switch to example-notebook
nb u example-notebook

For more commands and options, run nb help or nb help <subcommand>

Options:
  -b, --browse                Add using a terminal or GUI web browser.
  -c, --content <content>     The content for the new note.
  --edit                      Open the note in the editor before saving when
                              content is piped or passed as an argument.
  -e, --encrypt               Encrypt the note with a password.
  -f, --filename <filename>   The filename for the new note.
  --folder <folder-path>      Add within the folder located at <folder-path>.
  --tags <tag1>,<tag2>...     A comma-separated list of tags.
  -t, --title <title>         The title for a new note. If `--title` is
                              present, the filename is derived from the
                              title, unless `--filename` is specified.
  --type <type>               The file type for the new note, as a file
                              extension.

Description:
  Create a new note or folder.

  If no arguments are passed, a new blank note file is opened with `$EDITOR`,
  currently set to: example

  If a non-option argument is passed, `nb` will treat it as a <filename≥
  if a file extension is found. If no file extension is found,  `nb` will
  treat the string as <content> and will create a new note without opening the
  editor. `nb add` can also create a new note with piped content.

  `nb` creates Markdown files by default. To create a note with a
  different file type, use the extension in the filename or use the `--type`
  option. To change the default file type, use `nb set default_extension`.

  When the `-e` / `--encrypt` option is used, `nb` will encrypt the
  note with AES-256 using OpenSSL by default, or GPG, if configured in
  `nb set encryption_tool`.

Description:
  Browse, view, and edit linked notes, bookmarks, notebooks, folders, and
  other items using terminal and GUI web browsers.

  `browse` includes an embedded web application designed for terminal
  and GUI web browsers that renders [[wiki-style links]] and #tags as
  internal links, providing the ability to browse notes and notebooks,
  as well as seamlessly browse to and from the offsite links in
  bookmarks and notes.

  To link to a note or bookmark from another, include the selector for the
  target item within double square brackets anywhere in the linking document:

    # link to item 123 in the "sample" folder in the "example" notebook
    [[example:sample/123]]

    # link to the item titled "Example Title" in the "demo" notebook
    [[demo:Example Title]]

  `browse` supports `w3m` [1] and `links` [2], and depends on
  `ncat` [3] or `socat` [4] and `pandoc` [5]:

                   in the terminal web browser. If either `pandoc` or a
                   browser are unavailable, `-r` / `--render` is ignored.
  --title          Print the title of the note.

  -u, --updated    Print the date and time of the last recorded change.

Description:
  Show an item or notebook. Notes in text file formats can be rendered or
  printed to standard output. Non-text files are opened in your system's
  preferred app or program for that file type.

  By default, the item is opened using `less` or the program configured
  in the `$PAGER` environment variable. Use the following keys to navigate
  in `less` (see `man less` for more information):

    Key               Function
    ---               --------
    mouse scroll      Scroll up or down
    arrow up or down  Scroll one line up or down
    f                 Jump forward one window

    /<query>          Search for <query>
    n                 Jump to next <query> match
    q                 Quit

  To skip the pager and print to standard output, use the `-p` / `--print`
  option.

  `-r` / `--render` automatically uses either `w3m` [2] or `links` [3].
  To specify a preferred browser, set the `$BROWSER` environment variable
  in your .bashrc, .zshrc, or equivalent, e.g.: export BROWSER="links"

  If `bat` [4], `highlight` [5], or Pygments [6] is installed, notes are
  printed with syntax highlighting.

sync

↑ · See also: Git Sync, History, history, notebooks, remote, status

Usage:
  nb sync [-a | --all]

Options:
  -a, --all   Sync all unarchived notebooks.

Description:
  Sync the current notebook with its remote.

Private Repositories and Git Credentials:
  Syncing with private repositories requires configuring git to not prompt
  for credentials.

  For repositories cloned over HTTPS, credentials can be cached with git.
  For repositories cloned over SSH, keys can be added to the ssh-agent.

  More Information:
    https://github.com/xwmx/nb#private-repositories-and-git-credentials

Sync Conflict Resolution:
  When `nb sync` encounters a conflict in a text file and can't merge
  overlapping local and remote changes, both versions are saved in the
  file, separated by git conflict markers. Use `nb edit` to remove the
  conflict markers and delete any unwanted text.

  When `nb sync` encounters a conflict in a binary file, such as an
  encrypted note or bookmark, both versions of the file are saved in the
  notebook as individual files, one with `--conflicted-copy` appended to
  the filename.

nb Notebook Specification

An nb notebook is a directory that contains a valid .git directory, indicating that it has been initialized as a git repository, and a .index file in the root directory.

.index Files

A notebook folder index is a text file named .index in any folder within the notebook directory. .index contains a list of visible filenames within the folder, one per line, and the line number of each filename represents the id. .index files are included in the git repository so ids are preserved across systems.

Operations

index Subcommand

nb manages the .index of each folder within a notebook using an internal index subcommand.

nb help index

Usage:
  nb index add <filename>
  nb index delete <filename>
  nb index edit
  nb index get_basename <id>
  nb index get_id <filename>
  nb index get_max_id
  nb index rebuild [--ancestors]
  nb index reconcile [--ancestors] [--commit]
  nb index show
  nb index update <existing-filename> <new-filename>
  nb index verify
  nb index <subcommand> <options>... [<folder-path>]

Options:
  --ancestors   Perform the action on all folders within the notebook that
                are ancestors of the current folder.
  --commit      Commit changes to git.

Subcommands:
  add           Add <filename> to the index.
  delete        Delete <filename> from the index.
  edit          Open the index file in `$EDITOR`.
  get_basename  Print the filename / basename at the specified <id>.
  get_id        Get the id for <filename>.
  get_max_id    Get the maximum id for the folder.
  rebuild       Rebuild the index, listing files by last modified, reversed.
                Some ids will change. Prefer `nb index reconcile`.
  reconcile     Remove duplicates and update index for added and deleted files.
  show          Print the index.
  update        Overwrite the <existing-filename> entry with <new-filename>.
  verify        Verify that the index matches the folder contents.

Description:
  Manage the index for the current folder or the folder at <folder-path>,
  which can be passed as the final argument to any `index` subcommand.

  `index` is used internally by `nb` and using it manually will
  probably corrupt the index. If something goes wrong with an index,
  fix it with `nb index reconcile`.

  An index is a text file named '.index' in any folder within a notebook.
  .index contains a list of filenames and the line number of each filename
  represents the id. .index files are included in the git repository so
  ids are preserved across systems.

.pindex Files

Any folder may contain an optional plain text file named .pindex containing a list of basenames from that folder, one per line, that should be treated as pinned, meaning they appear first in some list operations, including nb and nb ls. Entries are added to a .pindex file with nb pin and removed with nb unpin.

Archived Notebooks

A notebook is considered archived when it contains a file named .archived at the root level of the notebook directory.

Tests

With more than 2,200 tests spanning tens of thousands of lines, nb is really mostly a test suite. Tests run continuously via GitHub Actions on recent versions of both Ubuntu and macOS to account for differences between BSD and GNU tools and Bash versions. To run the tests locally, install Bats and the recommended dependencies, then run bats test within the project root directory. Run groups of tests with globbing, e.g., bats test/browse* and bats test/folders*.
