Stabiln\u00e1 verzia s\u00faboru z\u00e1kladn\u00fdch syst\u00e9mov\u00fdch util\u00edt GNU Coreutils 9.1 je dostupn\u00e1, vr\u00e1tane programov ako sort, cat, chmod, chown, chroot, cp, date, dd, echo, hostname, id, ln, ls a \u010fal\u0161\u00edch. <\/p>\n

Do utilitu dd bola pridan\u00e1 podpora alternat\u00edvnych n\u00e1zvov mo\u017enost\u00ed iseek=N pre skip=N a oseek=N pre seek=N, ktor\u00e9 sa pou\u017e\u00edvaj\u00fa v verzii dd pre BSD syst\u00e9my.\n
Do dircolors bola pridan\u00e1 mo\u017enos\u0165 «—print-ls-colors» pre preh\u013eadn\u00e9 a oddelen\u00e9 zobrazenie farieb, definovan\u00fdch v premenej prostredia LS_COLORS. Do dircolors bola tie\u017e pridan\u00e1 podpora pre premenn\u00fa prostredia COLORTERM okrem TERM.\n

Do n\u00e1stroja ‘date’ bola pridan\u00e1 mo\u017enos\u0165 ‘—resolution’ na zobrazenie \u00fadajov o presnosti sledovania \u010dasu.\n

V chown a chroot je zabezpe\u010den\u00e9 zobrazenie varovania pri pou\u017eit\u00ed syntaxe «chown root.root f» namiesto «chown root:root f», preto\u017ee m\u00f4\u017eu vznikn\u00fa\u0165 probl\u00e9my na syst\u00e9moch, kde sa v men\u00e1ch pou\u017e\u00edvate\u013eov povo\u013euje pou\u017e\u00edva\u0165 bodku).\n

V ls a stat boli vypnut\u00e9 pokusy o automatick\u00e9 montovanie s\u00faborov. Na automatick\u00e9 montovanie je potrebn\u00e9 jasne uvies\u0165 mo\u017enos\u0165 «stat —cached=never». <\/ul>\n
