Mtundu wokhazikika wa GNU Coreutils 9.0 seti ya zofunikira zoyambira zilipo, zomwe zimaphatikizapo mapulogalamu monga sort, cat, chmod, chown, chroot, cp, date, dd, echo, hostname, id, ln, ls, etc. Kusintha kwakukulu kwa nambala yamtunduwu kumachitika chifukwa cha kusintha kwamachitidwe azinthu zina.
Zosintha zazikulu:
- The cp ndi kukhazikitsa zida zosasinthika kuti muzitha kukopera polemba (pogwiritsa ntchito ioctl ficlone kugawana deta pamafayilo angapo m'malo mopanga chojambula chathunthu).
- Zida za cp, install, ndi mv zimagwiritsa ntchito njira zomwe zimaperekedwa ndi machitidwe kuti zifulumizitse kukopera (pogwiritsa ntchito copy_file_range system call kuti ipange kernel-side kukopera kokha, popanda kusamutsa deta kuti igwiritse ntchito kukumbukira pamalo ogwiritsira ntchito).
- Zida za cp, install, ndi mv zimagwiritsa ntchito kuyimba kosavuta komanso kunyamulika kwa lseek+SEEK_HOLE m'malo mwa ioctl+FS_IOC_FIEMAP kuti azindikire zosoweka zamafayilo.
- Wothandizira wc amagwiritsa ntchito malangizo a AVX2 kuti afulumizitse kuwerengera kuchuluka kwa mizere. Mukamagwiritsa ntchito kukhathamiritsa uku, liwiro la wc lidakwera nthawi 5.
- Njira ya "-a" (--algorithm) yawonjezedwa ku cksum utility kuti musankhe algorithm ya hashing. Kuti mufulumizitse kuwerengera ma checksums mu cksum utility, malangizo a pclmul amagwiritsidwa ntchito pogwiritsa ntchito "--algorithm=crc" mode, yomwe imafulumizitsa kuwerengera mpaka nthawi 8. Pa machitidwe opanda chithandizo cha pclmul, crc mode ndi nthawi 4 mofulumira. Ma algorithms otsala a hashing (sum, md5sum, b2sum, sha*sum, sm3, etc.) amayendetsedwa poyitana ntchito za libcrypto.
- Mu md5sum, cksum, sha *sum ndi b2sum utility, pogwiritsa ntchito mbendera ya "--check" imalola kukhalapo kwa mndandanda wa CRLF kumapeto kwa mzere wa checksum. "cksum --check" imapereka chidziwitso chodziwikiratu cha hashing algorithm yomwe imagwiritsidwa ntchito.
- The ls utility yawonjezera njira ya "--sort=width" kuti musanthule ndi kutalika kwa dzina lafayilo, komanso "--zero" njira yothetsa mzere uliwonse ndi zilembo zopanda pake. Khalidwe lakale labwezedwa, zomwe zimapangitsa kuti chikwatu chopanda kanthu chiwonetsedwe m'malo mwa cholakwika pokonza chikwatu chakutali.
- Df utility imagwiritsa ntchito kuzindikira kwamafayilo a netiweki acfs, coda, fhgfs, gpfs, ibrix, ocfs2 ndi vxfs.
- Thandizo lamitundu yamafayilo "devmem", "exfat", "secretmem", "vboxsf" ndi "zonefs" yawonjezedwa kuzinthu zowerengera ndi mchira. Kwa "vboxsf", kuvota kumagwiritsidwa ntchito kutsata kusintha kwa "tail -f", ndipo kwa ena onse, inotify imagwiritsidwa ntchito.
