Ib qho ruaj khov version ntawm GNU Coreutils 9.6 cov txheej txheem kev siv hluav taws xob tau raug luam tawm, uas suav nrog cov kev pab cuam xws li xaiv, miv, chmod, chown, chroot, cp, hnub tim, dd, ncha, hostname, id, ln, ls, thiab lwm yam.
Qhov tseem ceeb innovation:
- Qhov kev xaiv "-a crc32b" tau ntxiv rau cksum utility los xam cov checksums raws li ITU V.42 specification, siv, piv txwv li, hauv gzip. Ntxiv kev ua tau zoo optimization siv pclmul qhia. Txhawm rau ua kom lub sijhawm ua haujlwm ntawm "cksum -a crc", SIMD txuas ntxiv AVX2, AVX512 thiab ARMv8 tau siv, uas hauv kev sim txo cov sijhawm suav los ntawm 40%, 60% thiab 80%, raws li.
- Qhov kev xaiv "--sort=name" tau ntxiv rau ls cov nqi hluav taws xob kom meej meej teeb tsa los ntawm cov ntaub ntawv npe.
- Printf tam sim no txhawb POSIX: 2024 indexed sib cav hauv hom "%
- Lub peev xwm siv cov "tus neeg teb xov tooj nrog cov hlua tau ntxiv rau qhov ntsuas hluav taws xob (POSIX: 2024).
- Cov kev xaiv "-f" thiab "-p" tau qhia hauv POSIX: 2024 tus qauv tau ntxiv rau lub sijhawm siv hluav taws xob, uas yog luv luv ntawm "--foreground" thiab "--preserve-status" xaiv.
- Hauv kev faib khoom siv, kev ua haujlwm ntawm cov ntaub ntawv hauv pseudo-FS, xws li / proc, tau nrawm dua.
- Kev them nyiaj yug rau "bcachefs" thiab "pidfs" hom ntaub ntawv tau raug ntxiv rau cov khoom siv hluav taws xob thiab cov khoom siv. Txhawm rau tso saib hom FS, cov lus txib "stat -f -c%T" tau ntxiv. Cov lus txib "tail -f" siv cov txheej txheem inotify rau "bcachefs" thiab "pidfs" cov ntaub ntawv systems.
- Hauv cov khoom siv hluav taws xob wc, qhov tsawg kawg nkaus ntawm kev nyeem ntawv ib ntus tau nce los ntawm 16KiB txog 256KiB. Thaum nyeem cov ntaub ntawv cached, "wc -l" kev ua tau zoo tuaj txog li 10%.
