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

• cpz
• rmz

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.
