Description
I built GRSH because I wanted a modern, memory-safe shell that feels native to FreeBSD but works seamlessly on macOS.While there are many shells out there, GRSH is my take on a minimal, fast, and secure command interpreter written entirely in Rust. It's designed for users who want the safety guarantees of Rust without the overhead of more bloated alternatives.I'm currently working on the official FreeBSD port. I’d love to get feedback on the shell's behavior and performance from the community.Github: https://github.com/antoniomalara301289/grsh

Could you build this?
Partial While basic shell parsing and execution can be vibe-coded, building a high-performance, POSIX-compatible shell on FreeBSD/macOS requires intricate OS-level systems programming.
What it would actually take: A proper Unix shell requires Rust with deep libc integration (termios, ioctl, fork/exec, pipe management, signal handling like SIGTSTP/SIGINT/SIGCHLD, and job control). The tricky parts are race-free signal handling, process group management, robust terminal line discipline, and FreeBSD-specific kernel APIs, requiring solid low-level Unix systems programming expertise.
