GNU Coreutils Rewrite in Rust

This project is a rewrite of some of the GNU Coreutils in Rust. It is created and used for educational purposes only, primarily to learn Rust and to peek under the hood of the utility programs that have shaped the last half century of computing.

For the real deal, see the GNU Coreutils

About the Project

• Educational initiative to learn Rust.
• Explore the inner workings of classic GNU/Linux utilities and see the differences and similarities between the GNU utilities and their BSD equivalence (appears that the BSD versions are much simpler than the GNU versions).

Disclaimer

⚠️ Educational Use Only
This project is primarily a learning exercise and not intended for production environments. These implementations:

• Are not as feature-complete as their GNU counterparts
• Lack comprehensive error handling
• May not cover all edge cases
• Have not undergone rigorous security auditing

For production systems, I strongly recommend using:

• The official GNU Coreutils implementations (GNU.org)
• Your operating system's built-in utilities (BSD-derived utilities are maintained as part of their respective operating systems)

Implemented Utilities

• cal
• cat
• comm
• cut
• echo
• find
• fortune
• grep
• head
• ls
• tail
• uniq
• wc
