You can find more details in [the documentation](https://clementtsang.github.io/bottom/nightly/usage/general-usage/). ## Support ### Official bottom _officially_ supports the following operating systems and corresponding architectures: - macOS (`x86_64`, `aarch64`) - Linux (`x86_64`, `i686`, `aarch64`) - Windows (`x86_64`, `i686`) These platforms are tested to work for the most part and issues on these platforms will be fixed if possible. Furthermore, binaries are built and tested using the most recent version of stable Rust at the time. For more details on supported platforms and known problems, check out [the documentation](https://clementtsang.github.io/bottom/nightly/support/official/). ### Unofficial bottom may work on a number of platforms that aren't officially supported. Note that unsupported platforms: - Might not be tested in CI to build or pass tests (see [here](./.github/workflows/ci.yml) for checked platforms). - Might not be properly tested by maintainers prior to a stable release. - May only receive limited support, such as missing features or bugs that may not be fixed. Note that some unsupported platforms may eventually be officially supported (e.g., FreeBSD). A non-comprehensive list of some currently unofficially supported platforms that may compile/work include: - FreeBSD (`x86_64`) - Linux (`armv6`, `armv7`, `powerpc64le`, `riscv64gc`) - Android (`arm64`) For more details on unsupported platforms and known problems, check out [the documentation](https://clementtsang.github.io/bottom/nightly/support/unofficial/). ## Installation ### Cargo Installation via `cargo` can be done by installing the [`bottom`](https://crates.io/crates/bottom) crate: ```bash # You might need to update the stable version of Rust first. # Other versions might work, but this is not guaranteed. rustup update stable # Install the binary from crates.io. cargo install bottom --locked # If you use another channel by default, you can specify # the what channel to use like so: cargo +stable install bottom --locked # --locked may be omitted if you wish to not use the # locked crate versions in Cargo.lock. However, be # aware that this may cause problems with dependencies. cargo install bottom ``` Alternatively, if you can use `cargo install` using the repo as the source. ```bash # You might need to update the stable version of Rust first. # Other versions might work, but this is not guaranteed. rustup update stable # Option 1 - Download an archive from releases and install curl -LO https://github.com/ClementTsang/bottom/archive/0.10.2.tar.gz tar -xzvf 0.10.2.tar.gz cargo install --path . --locked # Option 2 - Manually clone the repo and install git clone https://github.com/ClementTsang/bottom cd bottom cargo install --path . --locked # Option 3 - Install using cargo with the repo as the source cargo install --git https://github.com/ClementTsang/bottom --locked # You can also pass in the target-cpu=native flag for # better CPU-specific optimizations. For example: RUSTFLAGS="-C target-cpu=native" cargo install --path . --locked ``` ### Arch Linux bottom is available as an [official package](https://archlinux.org/packages/extra/x86_64/bottom/) that can be installed with `pacman`: ```bash sudo pacman -S bottom ``` If you want the latest changes that are not yet stable, you can also install `bottom-git` [from the AUR](https://aur.archlinux.org/packages/bottom-git). For example, to install with `paru`: ```bash sudo paru -S bottom-git ``` ### Debian / Ubuntu A `.deb` file is provided on each [stable release](https://github.com/ClementTsang/bottom/releases/latest) and [nightly builds](https://github.com/ClementTsang/bottom/releases/tag/nightly) for x86, aarch64, and armv7 (note stable ARM builds are only available for 0.6.8 and later). An example of installing this way: ```bash # x86-64 curl -LO https://github.com/ClementTsang/bottom/releases/download/0.10.2/bottom_0.10.2_amd64.deb sudo dpkg -i bottom_0.10.2_amd64.deb # ARM64 curl -LO https://github.com/ClementTsang/bottom/releases/download/0.10.2/bottom_0.10.2_arm64.deb sudo dpkg -i bottom_0.10.2_arm64.deb # ARM curl -LO https://github.com/ClementTsang/bottom/releases/download/0.10.2/bottom_0.10.2_armhf.deb sudo dpkg -i bottom_0.10.2_armhf.deb ``` ### Exherbo Linux bottom is available as a [rust package](https://gitlab.exherbo.org/exherbo/rust/-/tree/master/packages/sys-process/bottom) that can be installed with `cave`: ```bash cave resolve -x repository/rust cave resolve -x bottom ``` ### Fedora / CentOS / AlmaLinux / Rocky Linux bottom is available in [COPR](https://copr.fedorainfracloud.org/coprs/atim/bottom/): ```bash sudo dnf copr enable atim/bottom -y sudo dnf install bottom ``` `.rpm` files are also generated for x86 in the [releases](https://github.com/ClementTsang/bottom/releases) page.

You can then run by doing: ```bash ./btm ``` or by installing to your system following the procedures for installing binaries to your system. #### Auto-completion The release binaries are packaged with shell auto-completion files for bash, fish, zsh, and Powershell. To install them: - For bash, move `btm.bash` to `$XDG_CONFIG_HOME/bash_completion or /etc/bash_completion.d/`. - For fish, move `btm.fish` to `$HOME/.config/fish/completions/`. - For zsh, move `_btm` to one of your `$fpath` directories. - For PowerShell, add `_btm.ps1` to your PowerShell [profile](). The individual auto-completion files are also included in the stable/nightly releases as `completion.tar.gz`. ## Usage You can run bottom using `btm`. - For help on flags, use `btm -h` for a quick overview or `btm --help` for more details. - For info on key and mouse bindings, press `?` inside bottom or refer to the [documentation](https://clementtsang.github.io/bottom/nightly/). You can find more information on usage in the [documentation](https://clementtsang.github.io/bottom/nightly/). ## Configuration bottom accepts a number of command-line arguments to change the behaviour of the application as desired. Additionally, bottom will automatically generate a configuration file on the first launch, which one can change as appropriate. More details on configuration can be found [in the documentation](https://clementtsang.github.io/bottom/nightly/configuration/config-file/). ## Troubleshooting If some things aren't working, give the [troubleshooting page](https://clementtsang.github.io/bottom/nightly/troubleshooting) a look. If things still aren't working, then consider opening [a question](https://github.com/ClementTsang/bottom/discussions) or filing a [bug report](https://github.com/ClementTsang/bottom/issues/new/choose). ## Contribution Whether it's reporting bugs, suggesting features, maintaining packages, or submitting a PR, contribution is always welcome!

## Thanks - This project is very much inspired by [gotop](https://github.com/xxxserxxx/gotop), [gtop](https://github.com/aksakalli/gtop), and [htop](https://github.com/htop-dev/htop/). - This application was written with many, _many_ libraries, and built on the work of many talented people. This application would be impossible without their work. I used to thank them all individually but the list got too large... - And of course, another round of thanks to all the contributors and package maintainers!
