README.mdfork it — it’s yours
brush (Bo(u)rn(e) RUsty SHell) is a modern bash- and POSIX- compatible shell written in Rust. Run your existing scripts and .bashrc unchanged -- with syntax highlighting and auto-suggestions built in.
At a glance
✅ Your existing .bashrc just works—aliases, functions, completions, all of it.
✨ Syntax highlighting and auto-suggestions built in.
🧪 Validated against bash with ~1700 compatibility tests.
🧩 Easily embeddable in your Rust apps using brush_core::Shell.
⚠️ Not everything works yet:
selectand some edge cases aren't supported. See the Compatibility Reference for details.
Quick start:
$ cargo binstall brush-shell # using cargo-binstall $ brew install brush # using Homebrew $ pacman -S brush # Arch Linux $ cargo install --locked brush-shell # Build from sources
brush is ready for use as a daily driver. We test every change against bash to keep it that way.
More detailed installation instructions are available below.

Installation
When you run brush, it should look exactly as bash does on your system: it processes your .bashrc and
other standard configuration. If you'd like to distinguish the look of brush from the other shells
on your system, you may author a ~/.brushrc file.
🍺 Installing using Homebrew (macOS/Linux)
Homebrew users can install using the brush formula:
brew install brush
Installing on Arch Linux
Arch Linux users can install brush from the official extra repository:
pacman -S brush
Installing on MSYS2
MSYS2 users can install brush from the repository:
pacman -S mingw-w64-ucrt-x86_64-brush # or mingw-w64-clang-x86_64-brush or mingw-w64-clang-aarch64-brush
🚀 Installing prebuilt binaries via `cargo binstall`
You may use cargo binstall to install pre-built brush binaries. Once you've installed cargo-binstall you can run:
cargo binstall brush-shell
🚀 Installing prebuilt binaries from GitHub
We publish prebuilt binaries of brush for Linux (x86_64, aarch64) and macOS (aarch64) to GitHub for official releases. You can manually download and extract the brush binary from one of the archives published there, or otherwise use the GitHub CLI to download it, e.g.:
gh release download --repo reubeno/brush --pattern "brush-x86_64-unknown-linux-gnu.*"
After downloading the archive for your platform, you may verify its authenticity using the GitHub CLI, e.g.:
gh attestation verify brush-x86_64-unknown-linux-gnu.tar.gz --repo reubeno/brush
🐧 Installing using Nix
If you are a Nix user, you can use the registered version:
nix run 'github:NixOS/nixpkgs/nixpkgs-unstable#brush' -- --version
🔨 Building from sources
To build from sources, first install a working (and recent) rust toolchain; we recommend installing it via rustup. Then run:
cargo install --locked brush-shell
