bottom (btm)

A customizable cross-platform graphical process/system monitor for the terminal.
Supports Linux, macOS, and Windows. Inspired by gtop, gotop, and htop.

Quick demo recording showing off bottom's searching, expanding, and process killing.

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:
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 options or a config file, such as:
- Custom and built-in colour themes
- Customizing widget behaviour
- Changing the layout of widgets
- Filtering out entries in some widgets
And more:
- An htop-inspired basic mode
- Expansion, which focuses on just one widget
And more!

You can find more details in the documentation.

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.

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.

Installation

Cargo

Installation via cargo can be done by installing the bottom crate:

# 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, you can use cargo install using the repo as the source.

# 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/0.11.4.tar.gz
tar -xzvf 0.11.4.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 to try to
# use better CPU-specific optimizations. For example:
RUSTFLAGS="-C target-cpu=native" cargo install --path . --locked

For PowerShell, add _btm.ps1 to your PowerShell [profile]!(https://docs.microsoft.com/en-us/previous-versions//bb613488(v=vs.85)).
For Elvish, the completion file is btm.elv.

Thanks

This project is very much inspired by gotop, gtop, and htop.
This application was written with many, many libraries, as well as many services and programs, all built on top of the work of many talented people. bottom would not exist without all of this.
And of course, thank you again to all contributors and package maintainers!
I also really appreciate anyone who has used bottom, and those who go out of their way to report bugs or suggest ways to improve things. I hope it’s been a useful tool for others.
To those who support my work financially via donations, thank you so much.
Also thanks to JetBrains for providing access to tools that I use to develop bottom as part of their open source support program.
