## Features
As (yet another) process/system visualization and management application, bottom supports the typical features:
- Graphical visualization widgets for:
- [CPU usage](https://bottom.pages.dev/nightly/usage/widgets/cpu/) over time, at an average and per-core level
- [RAM and swap usage](https://bottom.pages.dev/nightly/usage/widgets/memory/) over time
- [Network I/O usage](https://bottom.pages.dev/nightly/usage/widgets/network/) over time
with support for zooming in/out the current time interval displayed.
- Widgets for displaying info about:
- [Disk capacity/usage](https://bottom.pages.dev/nightly/usage/widgets/disk/)
- [Temperature sensors](https://bottom.pages.dev/nightly/usage/widgets/temperature/)
- [Battery usage](https://bottom.pages.dev/nightly/usage/widgets/battery/)
- [A process widget](https://bottom.pages.dev/nightly/usage/widgets/process/) for displaying, sorting, and searching info about processes, as well as support for:
- [Kill signals](https://bottom.pages.dev/nightly/usage/widgets/process/#process-termination)
- [Tree mode](https://bottom.pages.dev/nightly/usage/widgets/process/#tree-mode)
- [Cross-platform support](https://github.com/ClementTsang/bottom#support) for Linux, macOS, and Windows, with more planned in the future.
- [Customizable behaviour](https://bottom.pages.dev/nightly/configuration/command-line-options/) 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](https://bottom.pages.dev/nightly/usage/basic-mode/)
- [Expansion to focus on just one widget](https://bottom.pages.dev/nightly/usage/general-usage/#expansion)
You can find more details in [the documentation](https://bottom.pages.dev/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://bottom.pages.dev/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`, `loongarch64`)
- Android (`arm64`)
- Windows (`arm64`)
For more details on unsupported platforms and known problems, check out [the documentation](https://bottom.pages.dev/nightly/support/unofficial/).
## Installation
### Cargo
Installation via `cargo` can be done by installing the [`bottom`](https://crates.io/crates/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/0.12.3.tar.gz
tar -xzvf 0.12.3.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

### Contributors
Thanks to all contributors:
## 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](https://github.com/ClementTsang/bottom/blob/main/Cargo.toml),
[_many_ libraries](https://github.com/ClementTsang/bottom/blob/main/Cargo.lock), 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.
- Thanks to JetBrains for providing access to tools that I use to develop bottom
as part of their [open source support program](https://jb.gg/OpenSourceSupport).
- Also thanks to [SignPath.io](https://about.signpath.io/) for providing a free code signing service, and to the
[SignPath Foundation](https://signpath.org/) for the certificate.
