Iyo yakagadzikana vhezheni yeGNU Coreutils 9.0 seti yezvishandiso zvekutanga system iripo, inosanganisira zvirongwa zvakaita senge, katsi, chmod, chown, chroot, cp, date, dd, echo, hostname, id, ln, ls, nezvimwe. Iko kushanduka kukuru kwenhamba yevhezheni kunokonzerwa nekuchinja kwemaitiro ezvimwe zvinoshandiswa.
Kuchinja kukuru:
- Iyo cp uye yekuisa zvishandiso default kutevedzera-pa-kunyora modhi paunenge uchikopa (uchishandisa ioctl ficlone kugovera data pamafaira akawanda pane kugadzira yakazara clone).
- Iyo cp, yekumisikidza, uye mv zvishandiso zvinoshandisa masisitimu-akapihwa masisitimu ekukurumidzira kukopa mashandiro (uchishandisa iyo copy_file_range system call kuita kernel-side kukopa chete, pasina kuendesa data kugadzirisa ndangariro munzvimbo yemushandisi).
- Iyo cp, kuisa, uye mv zvishandiso zvinoshandisa iri nyore uye inotakurika lseek+SEEK_HOLE kufona pachinzvimbo cheioctl+FS_IOC_FIEMAP kuona mafaera asina.
- Iyo wc utility inoshandisa AVX2 mirairo kuti ikurumidze kuverenga nhamba yemitsara. Paunenge uchishandisa iyi optimization, wc kumhanya yakawedzera kashanu.
- Iyo "-a" (--algorithm) sarudzo yakawedzerwa kune cksum utility kusarudza hashing algorithm. Kuti kukurumidze kuverenga kwecheki mu cksum utility, pclmul mirairo inoshandiswa paunenge uchishandisa "--algorithm = crc" modhi, iyo inomhanyisa kuverenga kusvika ku8 nguva. Pane masisitimu asina pclmul rutsigiro, crc modhi inokurumidza 4 nguva. Iwo asara hashing algorithms (sum, md5sum, b2sum, sha*sum, sm3, nezvimwewo) anoitwa nekudaidza libcrypto mabasa.
- Mune md5sum, cksum, sha*sum uye b2sum zvinoshandiswa, uchishandisa "--check" mureza unobvumira kuvepo kweCRLF kutevedzana pamagumo emutsetse wecheki. "cksum --check" inopa kuona otomatiki kweiyo hashing algorithm inoshandiswa.
- The ls utility yakawedzera "--sort=width" sarudzo yekugadzirisa nehurefu hwezita rezita, pamwe ne "--zero" sarudzo yekumisa mutsara wega wega nehunhu husina maturo. Maitiro echinyakare adzoswa, zvichiita kuti dhairekitori risina chinhu rionekwe pachinzvimbo chekukanganisa paunenge uchigadzira dhairekitori riri kure.
- Iyo df utility inoshandisa kuona kwenetiweki faira masisitimu acfs, coda, fhgfs, gpfs, ibrix, ocfs2 uye vxfs.
- Tsigiro yemhando yefaira system "devmem", "exfat", "secretmem", "vboxsf" uye "zonefs" yakawedzerwa kune stat uye muswe zvinoshandiswa. Kune "vboxsf", polling inoshandiswa kutarisa shanduko mu "tail -f", uye kune imwe nzvimbo inotify inoshandiswa.
