Coreutils indeholder over hundrede v\u00e6rkt\u00f8jer, herunder sort, cat, chmod, chown, chroot, cp, date, dd, echo, hostname, id, ln og ls. Projektets m\u00e5l er at skabe en tv\u00e6rplatforms alternativ implementering af Coreutils, der kan k\u00f8re p\u00e5 platforme som Windows, Redox og Fuchsia. I mods\u00e6tning til GNU Coreutils distribueres Rust-implementeringen under den permissive MIT-licens i stedet for GPL-copyleft-licensen.         <\/p>\n<p>I den nye version af uutils er version 9.4 af GNU Coreutils blevet brugt som reference. Kompatibiliteten med reference-testpakken for GNU Coreutils er forbedret, hvor 437 tests blev best\u00e5et (i den tidligere version 422), 117 (132) tests fejlede, og 50 (50) tests blev udeladt. Der er opn\u00e5et fuld kompatibilitet med GNU Coreutils for v\u00e6rkt\u00f8jerne base64, basename, cat, chgrp, chmod, chown, dirname, expand, fold, groups, join, ln, mktemp, nice, nl, nproc, paste, pathchk, printenv, realpath, shuf, sleep, split, sync, unexpand, uniq, wc og yes.     <\/p>\n<p>Funktionerne er udvidet, kompatibiliteten er forbedret, og der er tilf\u00f8jet manglende indstillinger til v\u00e6rkt\u00f8jerne base32, base64, basenc, basename, cat, chcon, chmod, cksum, cp, csplit, cut, dd, df, du, echo, env, expand, factor, fmt, hashsum, install, ln, ls, more, numfmt, odd, printf, pr, seq, shuf, sort, split, stat, tsort, tty, truncate, uname og uniq.      <center><img decoding=\"async\" alt=\"Udgivelsen af GNU Coreutils 9.5 og dens version p\u00e5 Rust \"
