O objetivo do projeto \u00e9 criar uma implementa\u00e7\u00e3o alternativa cross-platform do Coreutils, capaz de funcionar em plataformas como Windows, Redox e Fuchsia. Ao contr\u00e1rio do GNU Coreutils, a implementa\u00e7\u00e3o em Rust \u00e9 distribu\u00edda sob a licen\u00e7a permissiva MIT, em vez da licen\u00e7a copyleft GPL.         <\/p>\n<p>Na nova vers\u00e3o do uutils, a vers\u00e3o de refer\u00eancia utilizada \u00e9 a GNU Coreutils 9.4.

A compatibilidade total com o GNU Coreutils foi garantida para os utilit\u00e1rios base64, basename, cat, chgrp, chmod, chown, dirname, expand, fold, groups, join, ln, mktemp, nice, nl, nproc, paste,
