プロジェクトの歴史

The project presents itself as a modern Bash- and POSIX-compatible shell written in Rust. Its README emphasizes compatibility with existing `.bashrc` files, aliases, functions, and completions, while the compatibility reference documents a test suite that compares behavior against Bash.

Unlike experimental shells that define a new language first, brush starts from the existing shell ecosystem. Its published identity is conservative: preserve Bash behavior, add Rust implementation benefits and interactive features, and expose an embeddable `brush_core::Shell` for Rust programs.

採用の歴史

The official installation section lists Homebrew, Arch Linux, MSYS2, cargo-binstall, GitHub release binaries, and Nix, while the provided package facts also list Homebrew, MacPorts, Nix, and pacman. That puts brush in the normal multi-distribution pipeline for shell tools despite being a young implementation.

Adoption is still early compared with Bash, zsh, fish, or Oil/YSH, but the presence of distribution packages and a crates.io-oriented install path gives it several routes into developer workstations.

使われ方

brush can be launched as an interactive shell and is designed to read existing Bash startup files. The README says `.bashrc` should work unchanged, with optional `~/.brushrc` and TOML configuration for brush-specific behavior.

Its current use case is compatibility testing, interactive daily-driver experimentation, and embedding shell behavior inside Rust programs. The compatibility reference marks many Bash features as supported while still documenting gaps such as `select`, `wait -n`, and some background-job details.

パッケージ好きにとっての重要性

Shells are unusually package-sensitive because installing them is not enough: users may add them to login-shell databases, invoke them from scripts, and expect startup files and completions to work. brush is interesting because it tries to enter that old Unix contract while being implemented in Rust.

For maintainers, brush is a compact example of the modern Rust reimplementation wave applied to one of the hardest compatibility targets: Bash.
