Fast Unix Commands

cpz rmz Packaging status

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

Benchmarks are available under the comparisons folder.


  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.


  • 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.
