Features

As (yet another) process/system visualization and management application, bottom supports the typical features:

• Graphical visualization widgets for:

  • CPU usage over time, at an average and per-core level
  • RAM and swap usage over time
  • Network I/O usage over time

  with support for zooming in/out the current time interval displayed.

• Widgets for displaying info about:

  • Disk capacity/usage
  • Temperature sensors
  • Battery usage

• A process widget for displaying, sorting, and searching info about processes, as well as support for:

  • Kill signals
  • Tree mode

• Cross-platform support for Linux, macOS, and Windows, with more planned in the future.

• Customizable behaviour that can be controlled with command-line flags or a config file, such as:

  • Custom and pre-built colour themes
  • Changing the default behaviour of some widgets
  • Changing the layout of widgets
  • Filtering out entries in disk and temperature widgets

• Some other nice stuff, like:

  • An htop-inspired basic mode
  • Expansion, which focuses on just one widget

• And more!

You can find more details in the documentation.

Support

bottom officially supports the following operating systems and corresponding architectures:

• macOS (x86_64)
• Linux (x86_64, i686, aarch64)

You can uninstall via Control Panel, Options, or winget --uninstall bottom.

Building

There are a few ways to go about doing this manually. Note that in all cases, you would want to build using the most recent version of stable Rust:

# If required, update Rust on the stable channel
rustup update stable

# Download from releases and install
curl -LO https://github.com/ClementTsang/bottom/archive/0.6.3.tar.gz
tar -xzvf 0.6.3.tar.gz
cargo install --path .

# Clone from master and install manually
git clone https://github.com/ClementTsang/bottom
cd bottom
cargo install --path .

# Clone and install the newest master version all via Cargo
cargo install --git https://github.com/ClementTsang/bottom

Binaries

You can also try to use the generated release binaries and manually install them:

• Latest stable release, generated off of the release branch
• Latest nightly version, which is generated daily off of the master branch at 00:00 UTC

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.

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, refer to the documentation or press ? inside bottom.

You can generally find more information on usage in the documentation.

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.

Thanks

• This project is very much inspired by gotop, gtop, and 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 contributors and package maintainers!
