    From the README

    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.

    ✅ 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: select and some edge cases aren't supported. See the Compatibility Reference for details.

    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.
