btop++

This repository is a fork of the original btop repository designed to package and integrate with the Asciiville project. No new features or bug fixes are include in this repository. Packaging for a variety of platforms in the native packaging format is provided.

If your platform is not supported here then you may be able to find a binary btop distribution archive at the primary btop repository.

btop4win

First release of btop4win available at https://github.com/aristocratos/btop4win

16 January 2022

Release v1.2.0 with FreeBSD support. No release binaries for FreeBSD provided as of yet.

Again a big thanks to @joske for his porting efforts!

Since compatibility with Linux, macOS and FreeBSD are done, the focus going forward will be on new features like GPU monitoring.

13 November 2021

Release v1.1.0 with macOS support. Binaries in continuous-build-macos are only x86 for now. macOS binaries + installer are included for both x86 and ARM64 (Apple Silicon) in the releases.

Big thank you to @joske who wrote the vast majority of the implementation!

30 October 2021

Work on the OSX [macOS] and FreeBSD branches, both initiated and mostly worked on by @joske, will likely be completed in the coming weeks. The OSX [macOS] branch has some memory leaks that needs to be sorted out and both have some issues with the processes cpu usage calculation and other smaller issues that needs fixing.

If you want to help out, test for bugs/fix bugs or just try out the branches:

macOS / OSX

# Install and use Homebrew or MacPorts package managers for easy dependency installation
brew install coreutils make gcc@11
git clone https://github.com/aristocratos/btop.git
cd btop
git checkout OSX
gmake

FreeBSD

sudo pkg install gmake gcc11 coreutils git
git clone https://github.com/aristocratos/btop.git
cd btop
git checkout freebsd
gmake

Note that GNU make (gmake) is recommended but not required for macOS/OSX but it is required on FreeBSD.

6 October 2021

macOS development have been started by @joske, big thanks :) See branch OSX for current progress.

18 September 2021

The Linux version of btop++ is complete. Released as version 1.0.0

I will be providing statically compiled binaries for a range of architectures in every release for those having problems compiling.

For compilation GCC 10 is required, GCC 11 preferred.

Please report any bugs to the Issues page.

The development plan right now:

Windows support is not in the plans as of now, but if anyone else wants to take it on, I will try to help.

5 May 2021

This project is gonna take some time until it has complete feature parity with bpytop, since all system information gathering will have to be written from scratch without any external libraries. And will need some help in the form of code contributions to get complete support for BSD and macOS/OSX.

Description

Resource monitor that shows usage and stats for processor, memory, disks, network and processes.

C++ version and continuation of bashtop and bpytop.

Features

Themes

Btop++ uses the same theme files as bpytop and bashtop (some color values missing in bashtop themes) .

See themes folder for available themes.

The make install command places the default themes in [$PREFIX or /usr]/share/btop/themes. User created themes should be placed in $XDG_CONFIG_HOME/btop/themes or $HOME/.config/btop/themes.

Let me know if you want to contribute with new themes.

Support and funding

You can sponsor this project through github, see my sponsors page for options.

Or donate through paypal or ko-fi.

Any support is greatly appreciated!

Prerequisites

For best experience, a terminal with support for:

Also needs a UTF8 locale and a font that covers:

Installation

Binaries for Linux are statically compiled with musl and works on kernel 2.6.39 and newer

  1. Download btop-(VERSION)-(ARCH)-(PLATFORM).tbz from latest release and unpack to a new folder

    Notice! Use x86_64 for 64-bit x86 systems, i486 and i686 are 32-bit!

  2. Install (from created folder)

    • Run install.sh or:
    # use "make install PREFIX=/target/dir" to set target, default: /usr
# only use "sudo" when installing to a NON user owned directory
sudo make install

  3. (Optional) Set suid bit to make btop always run as root (or other user)

    Enables signal sending to any process without starting with sudo and can prevent /proc read permissions problems on some systems.

    • Run setuid.sh or:
    # run after make install and use same PREFIX if any was used at install
# set SU_USER and SU_GROUP to select user and group, default is root:root
sudo make setuid

Binary release (from native os repo)

Binary release on Homebrew (macOS (x86_64 & ARM64) / Linux (x86_64))

Compilation Linux

Needs GCC 10 or higher, (GCC 11 or above strongly recommended for better CPU efficiency in the compiled binary).

The makefile also needs GNU coreutils and sed (should already be installed on any modern distribution).

For a cmake based build alternative see the fork by @jan-guenter

  1. Install dependencies (example for Ubuntu 21.04 Hirsute)

    Use gcc-10 g++-10 if gcc-11 isn't available

    sudo apt install coreutils sed git build-essential gcc-11 g++-11

  2. Clone repository

    git clone https://github.com/aristocratos/btop.git
cd btop

  3. Compile

    Append VERBOSE=true to display full compiler/linker commands.

    Append STATIC=true for static compilation.

    Notice! If using LDAP Authentication, usernames will show as UID number for LDAP users if compiling statically with glibc.

    Append QUIET=true for less verbose output.

    Append STRIP=true to force stripping of debug symbols (adds -s linker flag).

    Append ARCH=<architecture> to manually set the target architecture. If omitted the makefile uses the machine triple (output of -dumpmachine compiler parameter) to detect the target system.

    Use ADDFLAGS variable for appending flags to both compiler and linker.

    For example: ADDFLAGS=-march=native might give a performance boost if compiling only for your own system.

    If g++ is linked to an older version of gcc on your system specify the correct version by appending CXX=g++-10 or CXX=g++-11.

    make

  4. Install

    Append PREFIX=/target/dir to set target, default: /usr

    Notice! Only use "sudo" when installing to a NON user owned directory.

    sudo make install

  5. (Optional) Set suid bit to make btop always run as root (or other user)

    No need for sudo to enable signal sending to any process and to prevent /proc read permissions problems on some systems.

    Run after make install and use same PREFIX if any was used at install.

    Set SU_USER and SU_GROUP to select user and group, default is root and root

    sudo make setuid

Compilation macOS OSX

Needs GCC 10 or higher, (GCC 11 or above strongly recommended for better CPU efficiency in the compiled binary).

GCC 12 needed for macOS Ventura. If you get linker errors on Ventura you'll need to upgrade your command line tools (Version 14.0) is bugged.

The makefile also needs GNU coreutils and sed.

Install and use Homebrew or MacPorts package managers for easy dependency installation

  1. Install dependencies (example for Homebrew)

    brew install coreutils make gcc@12

  2. Clone repository

    git clone https://github.com/aristocratos/btop.git
cd btop

  3. Compile

    Append VERBOSE=true to display full compiler/linker commands.

    Append STATIC=true for static compilation (only libgcc and libstdc++ will be static!).

    Append QUIET=true for less verbose output.

    Append STRIP=true to force stripping of debug symbols (adds -s linker flag).

    Append ARCH=<architecture> to manually set the target architecture. If omitted the makefile uses the machine triple (output of -dumpmachine compiler parameter) to detect the target system.

    Use ADDFLAGS variable for appending flags to both compiler and linker.

    For example: ADDFLAGS=-march=native might give a performance boost if compiling only for your own system.

    gmake

  4. Install

    Append PREFIX=/target/dir to set target, default: /usr

    Notice! Only use "sudo" when installing to a NON user owned directory.

    sudo gmake install

  5. (Recommended) Set suid bit to make btop always run as root (or other user)

    No need for sudo to see information for non user owned processes and to enable signal sending to any process.

    Run after make install and use same PREFIX if any was used at install.

    Set SU_USER and SU_GROUP to select user and group, default is root and wheel

    sudo gmake setuid

Compilation FreeBSD

Needs GCC 10 or higher, (GCC 11 or above strongly recommended for better CPU efficiency in the compiled binary).

Note that GNU make (gmake) is required to compile on FreeBSD.

  1. Install dependencies

    sudo pkg install gmake gcc11 coreutils git

  2. Clone repository

    git clone https://github.com/aristocratos/btop.git
cd btop

  3. Compile

    Append VERBOSE=true to display full compiler/linker commands.

    Append QUIET=true for less verbose output.

    Append STRIP=true to force stripping of debug symbols (adds -s linker flag).

    Append ARCH=<architecture> to manually set the target architecture. If omitted the makefile uses the machine triple (output of -dumpmachine compiler parameter) to detect the target system.

    Use ADDFLAGS variable for appending flags to both compiler and linker.

    For example: ADDFLAGS=-march=native might give a performance boost if compiling only for your own system.

    gmake

  4. Install

    Append PREFIX=/target/dir to set target, default: /usr

    Notice! Only use "sudo" when installing to a NON user owned directory.

    sudo gmake install

  5. (Recommended) Set suid bit to make btop always run as root (or other user)

    No need for sudo to see information for non user owned processes and to enable signal sending to any process.

    Run after make install and use same PREFIX if any was used at install.

    Set SU_USER and SU_GROUP to select user and group, default is root and wheel

    sudo gmake setuid

Installing the snap

btop

Note: there are now two snaps available: btop and btop-desktop. The desktop version is much larger and includes the desktop entries needed to allow for launching btop with a click.
