brush is a bash- and POSIX-compatible shell implemented in Rust, capable of running existing bash scripts and .bashrc files unchanged. It includes built-in syntax highlighting and auto-suggestions, and can be embedded in Rust applications via brush_core.

Use cases

• replace bash with a memory-safe shell
• run existing bash scripts unchanged
• interactive shell with syntax highlighting and autosuggestions
• embed a bash-compatible shell in a Rust application
• test shell script compatibility against bash

When to choose

• you want a Rust-based, memory-safe alternative to bash
• you need high bash/POSIX compatibility for daily interactive use
• you want modern shell UX features without switching to fish/zsh syntax
• you need an embeddable shell interpreter in Rust

When to avoid

• you rely on bash features like select or obscure edge cases not yet supported
• you need 100% bug-for-bash compatibility in production scripts
• you require zsh or fish specific features
