Fast Unix Commands

The FUC-ing project provides modern unix commands focused on performance:

• cpz: a zippy alternative to cp
• rmz: a zippy alternative to rm

Benchmarks are available under the comparisons folder and a brief technical overview is available at https://alexsaveau.dev/blog/fuc.

Goals

1. Performance: if a reasonable improvement can be made, it will be.
2. Efficiency: when only negligible performance improvements are left, remaining efforts are focussed on minimizing wasted compute.
3. Usability: where applicable, the UX of existing commands is improved.

Non-goals

• Portability: FUCs are primarily targeted at modern Linux installations. Support for other platforms is provided on a best-efforts basis.
• Compatibility: coreutils or its Rust re-implementation will have the broadest and most stable set of options.
