fselect

Find files with SQL-like queries

Why use fselect?

While it doesn't tend to fully replace traditional find and ls, fselect has these nice features:

• SQL-like (not real SQL, but highly relaxed!) grammar easily understandable by humans
• complex queries
• aggregate, statistics, date, and other functions
• search within archives
• .gitignore, .hgignore, and .dockerignore support (experimental)
• search by width and height of images, EXIF metadata
• search by MP3 info
• search by extended file attributes and Linux capabilities
• search by file hashes
• search by MIME type
• shortcuts to common file types
• interactive mode
• various output formatting (CSV, JSON, and others)

More is under way!

Documentation

More detailed description. Look at examples first.

Examples

Find temporary or config files (full path and size):

fselect size, path from /home/user where name = '*.cfg' or name = '*.tmp'

Windows users may omit the quotes:

fselect size, path from C:\Users\user where name = *.cfg or name = *.tmp

Or put all the arguments into the quotes like this:

fselect "name from /home/user/tmp where size > 0"

Search within a directory name with spaces (backticks are also supported):

fselect "name from '/home/user/dir with spaces' where size > 0"
fselect "name from `/home/user/dir with spaces` where size > 0"

Or simply escape the single quotes:

fselect name from \'/home/user/dir with spaces\' where size gt 0

Specify file size, get absolute path, and add it to the results:

cd /home/user
fselect size, abspath from ./tmp where size gt 2g
fselect fsize, abspath from ./tmp where size = 5m
fselect hsize, abspath from ./tmp where size lt 8k
fselect name, size from ./tmp where size between 5mb and 6mb

More complex query:

fselect "name from /tmp where (name = *.tmp and size = 0) or (name = *.cfg and size > 1000000)"

Aggregate functions (you can use curly braces if you want, and even combine them with the regular parentheses):

fselect "MIN(size), MAX{size}, AVG(size), SUM{size}, COUNT(*) from /home/user/Downloads"

Formatting functions:

fselect "LOWER(name), UPPER(name), LENGTH(name), YEAR(modified) from /home/user/Downloads"

Get the year of the oldest file:

fselect "MIN(YEAR(modified)) from /home/user"

Use single quotes if you need to address files with spaces:

fselect "path from '/home/user/Misc stuff' where name != 'Some file'"

Regular expressions of Rust flavor are supported:

fselect name from /home/user where path =~ '.*Rust.*'

Negate regular expressions:

fselect "name from . where path !=~ '^\./config'"

Simple globs expand automatically and work with = and != operators:

fselect name from /home/user where path = '*Rust*'

Classic LIKE:

fselect "path from /home/user where name like '%report-2018-__-__???'"

Exact match operators to search with regexps disabled:

fselect "path from /home/user where name === 'some_*_weird_*_name'"

Find files by date:

fselect path from /home/user where created = 2017-05-01
fselect path from /home/user where modified = today
fselect path from /home/user where accessed = yesterday
fselect "path from /home/user where modified = 'apr 1'"
fselect "path from /home/user where modified = 'last fri'"

Be more specific to match all files created at interval between 3PM and 4PM:

fselect path from /home/user where created = '2017-05-01 15'

And even more specific:

fselect path from /home/user where created = '2017-05-01 15:10'
fselect path from /home/user where created = '2017-05-01 15:10:30'

Date and time intervals possible (find everything updated since May 1st):

fselect path from /home/user where modified gte 2017-05-01

Default is current directory:

fselect path, size where name = '*.jpg'

Search within multiple locations:

fselect path from /home/user/oldstuff, /home/user/newstuff where name = '*.jpg'

With minimum and/or maximum depth specified (depth is a synonym for maxdepth):

fselect path from /home/user/oldstuff depth 5 where name = '*.jpg'
fselect path from /home/user/oldstuff mindepth 2 maxdepth 5, /home/user/newstuff depth 10 where name = '*.jpg'

Optionally follow symlinks:

fselect path, size from /home/user symlinks where name = '*.jpg'

Search within archives (currently only zip-archives are supported):

fselect path, size from /home/user archives where name = '*.jpg'

Or in combination:

fselect size, path from /home/user depth 5 archives symlinks where name = '*.jpg' limit 100

Enable .gitignore or .hgignore support:

fselect size, path from /home/user/projects gitignore where name = '*.cpp'
fselect size, path from /home/user/projects git where name = '*.cpp'    
fselect size, path from /home/user/projects hgignore where name = '*.py'        

Search by image dimensions:

fselect CONCAT(width, 'x', height), path from /home/user/photos where width gte 2000 or height gte 2000

Find square images:

fselect path from /home/user/Photos where width = height

Find images with a known name part but unknown extension:

fselect path from /home/user/projects where name = "*RDS*" and width gte 1

Find old-school rap MP3 files:

fselect duration, path from /home/user/music where genre = Rap and bitrate = 320 and mp3_year lt 2000  

Shortcuts to common file extensions:

fselect path from /home/user where is_archive = true
fselect path, mime from /home/user where is_audio = 1
fselect path, mime from /home/user where is_book != false

Even simpler way of using boolean columns:

fselect path from /home/user where is_doc
fselect path from /home/user where is_image
fselect path from /home/user where is_video

Find files with dangerous permissions:

fselect mode, path from /home/user where other_write or other_exec
fselect mode, path from /home/user where other_all

Simple glob-like expressions or even regular expressions on file mode are possible:

fselect mode, path from /home/user where mode = '*rwx'
fselect mode, path from /home/user where mode =~ '.*rwx$'

Find files by owner's uid or gid:

fselect uid, gid, path from /home/user where uid != 1000 or gid != 1000

Or by owner's or group's name:

fselect user, group, path from /home/user where user = mike or group = mike

Find special files:

fselect name from /usr/bin where suid
fselect path from /tmp where is_pipe
fselect path from /tmp where is_socket

Find files with xattrs, check if particular xattr exists, or get its value:

fselect "path, has_xattrs, has_xattr(user.test), xattr(user.test) from /home/user"

Include arbitrary text as columns:

fselect "name, ' has size of ', size, ' bytes'"

Group results:

fselect "ext, count(*) from /tmp group by ext"            

Order results:

fselect path from /tmp order by size desc, name
fselect modified, fsize, path from ~ order by 1 desc, 3

Finally limit the results:

fselect name from /home/user/samples limit 5 

Format output:

fselect size, path from /home/user limit 5 into json
fselect size, path from /home/user limit 5 into csv
fselect size, path from /home/user limit 5 into html
