RustBox 🦀📦

A BusyBox-style reimplementation of GNU coreutils in Rust.

RustBox provides a collection of small, fast, and reliable command-line utilities written in Rust.
Each utility is installed as its own binary (fastcat, fastgrep, …), similar to GNU coreutils but built the Rust way.

---

🚀 Goals

• Provide fast, memory-safe replacements for common Unix utilities.
• Learn and practice Rust systems programming.
• Keep utilities small and composable.
• Mimic familiar GNU coreutils behavior where possible.
