Thanks to [@bjia56](https://github.com/bjia56) for contributions. NetBSD support added. Thanks to [@fraggerfox](https://github.com/fraggerfox) for contributions. See [CHANGELOG.md](CHANGELOG.md) and latest [release](https://github.com/aristocratos/btop/releases/latest) for detailed list of new features, bug fixes and new themes. ##### 7 January 2024 Btop release v1.3.0 Big release with GPU support added for Linux and platform support for OpenBSD. Big thanks to [@romner-set](https://github.com/romner-set) (GPU support) and [@joske](https://github.com/joske) (OpenBSD support) for contributions. And a multitude of bugfixes and small changes, see [CHANGELOG.md](CHANGELOG.md) and latest [release](https://github.com/aristocratos/btop/releases/latest) for detailed list and attributions. See news entry below for more information regarding GPU support. ##### 25 November 2023 GPU monitoring added for Linux! Compile from git main to try it out. Use keys `5`, `6`, `7` and `0` to show/hide the gpu monitoring boxes. `5` = Gpu 1, `6` = Gpu 2, etc. Gpu stats/graphs can also be displayed in the "Cpu box" (not as verbose), see the cpu options menu for info and configuration. Note that the binaries provided on the release page (when released) and the continuous builds will not have gpu support enabled. Because the GPU support relies on loading of dynamic gpu libraries, gpu support will not work when also static linking. See [Compilation Linux](#compilation-linux) for more info on how to compile with gpu monitoring support. Many thanks to [@romner-set](https://github.com/romner-set) who wrote the vast majority of the implementation for GPU support. Big update with version bump to 1.3 coming soon. ##### 28 August 2022 [](https://github.com/aristocratos/btop4win) First release of btop4win available at https://github.com/aristocratos/btop4win <details> <summary>More...</summary> ##### 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](https://github.com/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](https://github.com/aristocratos/btop/actions/workflows/continuous-build-macos.yml) 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](https://github.com/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](https://github.com/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** ```bash # Install and use Homebrew or MacPorts package managers for easy dependency installation brew install coreutils make gcc@11 lowdown git clone https://github.com/aristocratos/btop.git cd btop git checkout OSX gmake ``` **FreeBSD** ```bash sudo pkg install gmake gcc11 coreutils git lowdown 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](https://github.com/joske), big thanks :) See branch [OSX](https://github.com/aristocratos/btop/tree/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](https://github.com/aristocratos/btop/issues/new?assignees=aristocratos&labels=bug&template=bug_report.md&title=%5BBUG%5D) page. The development plan right now: * 1.1.0 macOS [OSX] support * 1.2.0 FreeBSD support * 1.3.0 Support for GPU monitoring * 1.X.0 Other platforms and features... 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. </details> ## Documents **[CHANGELOG.md](CHANGELOG.md)** **[CONTRIBUTING.md](CONTRIBUTING.md)** **[CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md)** ## Description Resource monitor that shows usage and stats for processor, memory, disks, network and processes. C++ version and continuation of [bashtop](https://github.com/aristocratos/bashtop) and [bpytop](https://github.com/aristocratos/bpytop). ## Features * Easy to use, with a game inspired menu system. * Full mouse support, all buttons with a highlighted key is clickable and mouse scroll works in process list and menu boxes. * Fast and responsive UI with UP, DOWN keys process selection. * Function for showing detailed stats for selected process. * Ability to filter processes. * Easy switching between sorting options. * Tree view of processes. * Send any signal to selected process. * UI menu for changing all config file options. * Auto scaling graph for network usage. * Shows IO activity and speeds for disks. * Battery meter * Selectable symbols for the graphs. * Custom presets * And more... ## Themes Btop++ uses the same theme files as bpytop and bashtop (some color values missing in bashtop themes) . See [themes](https://github.com/aristocratos/btop/tree/main/themes) folder for available themes. The `make install` command places the default themes in `[$PREFIX or /usr/local]/share/btop/themes`. User created themes should be placed in `$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](https://github.com/sponsors/aristocratos) for options. Or donate through [paypal](https://paypal.me/aristocratos) or [ko-fi](https://ko-fi.com/aristocratos). Any support is greatly appreciated! ## Prerequisites For best experience, a terminal with support for: * 24-bit truecolor ([See list of terminals with truecolor support](https://github.com//termstandard/colors)) * 256-color terminals are supported through 24-bit to 256-color conversion when setting "truecolor" to False in the options or with "-lc/--low-color" arguments. * 16 color TTY mode will be activated if a real tty device is detected. Can be forced with "-t/--tty_on" arguments. * Wide characters (Are sometimes problematic in web-based terminals) Also needs a UTF8 locale and a font that covers: * Unicode Block “Braille Patterns” U+2800 - U+28FF (Not needed in TTY mode or with graphs set to type: block or tty.) * Unicode Block “Geometric Shapes” U+25A0 - U+25FF * Unicode Block "Box Drawing" and "Block Elements" U+2500 - U+259F ### **Optional Dependencies (Needed for GPU monitoring) (Only Linux)** GPU monitoring also requires a btop binary built with GPU support (`GPU_SUPPORT=true` flag). See [GPU compatibility](#gpu-compatibility) section for more about compiling with GPU support. * **NVIDIA** If you have an NVIDIA GPU you must use an official NVIDIA driver, both the closed-source and open-source ones have been verified to work. In addition to that you must also have the nvidia-ml dynamic library installed, which should be included with the driver package of your distribution. * **AMD** If you have an AMD GPU `rocm_smi_lib` is required, which may or may not be packaged for your distribution. * **INTEL** Requires a working C compiler if compiling from source - tested with GCC12 and Clang16. Also requires the user to have permission to read from SYSFS. Can be set with `make setcap` (preferred) or `make setuid` or by running btop with `sudo` or equivalent. ### **Notice (Text rendering issues)** * If you are having problems with the characters in the graphs not looking like they do in the screenshots, it's likely a problem with your systems configured fallback font not having support for braille characters. * See [Terminess Powerline](https://github.com/ryanoasis/nerd-fonts/tree/master/patched-fonts/Terminus/terminus-ttf-4.40.1) for an example of a font that includes the braille symbols. * See comments by @sgleizes [link](https://github.com/aristocratos/bpytop/issues/100#issuecomment-684036827) and @XenHat [link](https://github.com/aristocratos/bpytop/issues/100#issuecomment-691585587) in issue #100 for possible solutions. * If text are misaligned and you are using Konsole or Yakuake, turning off "Bi-Directional text rendering" is a possible fix. * Characters clipping in to each other or text/border misalignments is not bugs caused by btop, but most likely a fontconfig or terminal problem where the braille characters making up the graphs aren't rendered correctly. * Look to the creators of the terminal emulator you use to fix these issues if the previous mentioned fixes don't work for you. ## Screenshots #### Main UI showing details for a selected process  #### Main UI in TTY mode  #### Main UI with custom options  #### Main-menu  #### Options-menu  #### Help-menu  ## 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](https://github.com/aristocratos/btop/releases/latest) 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:** ```bash # use "make install PREFIX=/target/dir" to set target, default: /usr/local # only use "sudo" when installing to a NON user owned directory sudo make install ``` 3. **(Optional/Required for Intel GPU) Set extended capabilities or suid bit to btop** Enables signal sending to any process without starting with `sudo` and can prevent /proc read permissions problems on some systems. Is required for Intel GPU support. * **Run:** ```bash # run after make install and use same PREFIX if any was used at install sudo make setcap ``` * **or** ```bash # 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 ``` * **Uninstall** * **Run:** ```bash sudo make uninstall ``` * **Show help** ```bash make help ``` **Binary release (from native os repo)** * **openSUSE** * **Tumbleweed:** ```bash sudo zypper in btop ``` * For all other versions, see [openSUSE Software: btop](https://software.opensuse.org/package/btop) * **Fedora** ```bash sudo dnf install btop ``` * **RHEL/AlmaLinux 8+** ```bash sudo dnf install epel-release sudo dnf install btop ``` * **FreeBSD** ```sh pkg install btop ``` * **NetBSD** ```sh pkg_add btop ``` **Binary release on Homebrew (macOS (x86_64 & ARM64) / Linux (x86_64))** * **[Homebrew](https://formulae.brew.sh/formula/btop)** ```bash brew install btop ``` ## Compilation Linux Requires at least GCC 10 or Clang 16. The makefile also needs GNU coreutils and `sed` (should already be installed on any modern distribution). ### GPU compatibility Btop++ supports Nvidia and AMD GPUs and Intel IGPUs out of the box on Linux x86_64, provided you have the correct drivers and libraries. Gpu support for Nvidia or AMD will not work when static linking glibc (or musl, etc.)! For x86_64 Linux the flag `GPU_SUPPORT` is automatically set to `true`, to manually disable gpu support set the flag to false, like: `make GPU_SUPPORT=false` (or `cmake -DBTOP_GPU=false` with CMake) * **NVIDIA** You must use an official NVIDIA driver, both the closed-source and [open-source](https://github.com/NVIDIA/open-gpu-kernel-modules) ones have been verified to work. In addition to that you must also have the `nvidia-ml` dynamic library installed, which should be included with the driver package of your distribution. * **AMD** AMDGPU data is queried using the [ROCm SMI](https://github.com/rocm/rocm_smi_lib) library, which may or may not be packaged for your distribution. If your distribution doesn't provide a package, btop++ is statically linked to ROCm SMI with the `RSMI_STATIC=true` make flag. This flag expects the ROCm SMI source code in `lib/rocm_smi_lib`, and compilation will fail if it's not there. The latest tested version is 5.6.x, which can be obtained with the following command: ```bash git clone https://github.com/rocm/rocm_smi_lib.git --depth 1 -b rocm-5.6.x lib/rocm_smi_lib ``` <details> <summary> ### With Make </summary> 1. **Install dependencies (example for Ubuntu 21.04 Hirsute)** ```bash sudo apt install coreutils sed git build-essential gcc-11 g++-11 lowdown ``` 2. **Clone repository** ```bash git clone https://github.com/aristocratos/btop.git cd btop ``` 3. **Compile** ```bash make ``` Options for make: | Flag | Description | |---------------------------------|-------------------------------------------------------------------------| | `VERBOSE=true` | To display full compiler/linker commands | | `STATIC=true` | For static compilation | | `QUIET=true` | For less verbose output | | `STRIP=true` | To force stripping of debug symbols (adds `-s` linker flag) | | `DEBUG=true` | Sets OPTFLAGS to `-O0 -g` and enables more verbose debug logging | | `ARCH=<architecture>` | To manually set the target architecture | | `FORTIFY_SOURCE=false` | Disable fortification with `_FORTIFY_SOURCE=3` | | `GPU_SUPPORT=<true\|false>` | Enable/disable GPU support (Enabled by default on X86_64 Linux) | | `RSMI_STATIC=true` | To statically link the ROCm SMI library used for querying AMDGPU | | `ADDFLAGS=<flags>` | For appending flags to both compiler and linker | | `CXX=<compiler>` | Manually set which compiler to use | Example: `make ADDFLAGS=-march=native` might give a performance boost if compiling only for your own system.

To remove installed files, run ``` cat build/install_manifest.txt | xargs rm -irv ``` 6. **Cleanup build directory** ```bash cmake --build build -t clean ``` </details> ## Compilation OpenBSD Requires at least GCC 10. Note that GNU make (`gmake`) is required to compile on OpenBSD. <details> <summary> ### With gmake </summary> 1. **Install dependencies** ```bash pkg_add gmake gcc%11 g++%11 coreutils git lowdown ``` 2. **Clone repository** ```bash git clone https://github.com/aristocratos/btop.git cd btop ``` 3. **Compile** ```bash gmake CXX=eg++ ``` Options for make: | Flag | Description | |---------------------------------|-------------------------------------------------------------------------| | `VERBOSE=true` | To display full compiler/linker commands | | `STATIC=true` | For static compilation (only libgcc and libstdc++) | | `QUIET=true` | For less verbose output | | `STRIP=true` | To force stripping of debug symbols (adds `-s` linker flag) | | `DEBUG=true` | Sets OPTFLAGS to `-O0 -g` and enables more verbose debug logging | | `ARCH=<architecture>` | To manually set the target architecture | | `FORTIFY_SOURCE=false` | Disable fortification with `_FORTIFY_SOURCE=3` | | `ADDFLAGS=<flags>` | For appending flags to both compiler and linker | | `CXX=<compiler>` | Manually set which compiler to use | Example: `gmake ADDFLAGS=-march=native` might give a performance boost if compiling only for your own system. 4. **Install** ```bash sudo gmake install ``` Append `PREFIX=/target/dir` to set target, default: `/usr/local` Notice! Only use "sudo" when installing to a NON user owned directory. 5. **(Recommended) Set suid bit to make btop always run as root (or other user)** ```bash sudo gmake setuid ``` 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` * **Uninstall** ```bash sudo gmake uninstall ``` * **Remove any object files from source dir** ```bash gmake clean ``` * **Remove all object files, binaries and created directories in source dir** ```bash gmake distclean ``` * **Show help** ```bash gmake help ``` </details> <details> <summary> ### With CMake (Community maintained) </summary> 1. **Install build dependencies** Requires GCC, CMake, Ninja, Lowdown and Git _**Note:** LLVM's libc++ shipped with OpenBSD 7.4 is too old and cannot compile btop._ ```bash pkg_add cmake g++%11 git ninja lowdown ``` 2. **Clone the repository** ```bash git clone https://github.com/aristocratos/btop.git && cd btop ``` 3. **Compile** ```bash # Configure CXX=eg++ cmake -B build -G Ninja # Build cmake --build build ``` This will automatically build a release version of btop.
