Core POSIX command line utilities in safe Rust

posixutils-rs

This is a suite of Rust-native core command line utilties (cp, mv, rm, ls, ...) using SuSv3 as the base POSIX specification.

Goals

The goal is to create clean, race-free userland utilities that are POSIX compliant, maximizing compatibility with existing shell scripts while minimizing bloat.

Implementation goals include clean, safe Rust code and maximal use of Rust community crates. This project's utilities should "look like normal Rust programs."

Contributions are welcome. Developers and helpers, please read CONTRIBUTING for details.

Core specification: https://pubs.opengroup.org/onlinepubs/9699919799/

Non-goals

It is not a goal to be compatible with GNU utilities, which are sometimes viewed as bloated and overloaded with rarely-used options.

Popular GNU options will be supported by virtue of the "don't break scripts" rule. Unpopular options will not be implemented, to prevent bloat.
