ICoreutils yiphakheji yesoftware ephuhliswe yiprojekthi ye-GNU equlathe uninzi lwezixhobo ezisisiseko njengekati, ls, kunye nerm ezifunekayo kwiindlela zokusebenza ezifana ne-Unix.
Kutshanje kwaziswaukukhululwa koguqulelo olutsha oluzinzileyo ukusuka kwiseti yezinto ezisisiseko zenkqubo GNU Coreutils 9.2 equka iinkqubo ezifana nokuhlela, ikati, i-chmod, i-chown, i-chroot, i-cp, umhla, i-dd, i-echo, igama lenginginya, i-id, ln, ls, njl.
I-Coreutils (okanye i-GNU Core Utilities) yindibaniselwano yeepakethe ezintathu zangaphambili: izixhobo zefayile (iifayile), izixhobo zeqokobhe (i-shellutils) kunye ne-word processing utility (textutils).
Izinto ezingundoqo ze-GNU xhasa iinketho zomtya omde njenge parameters kwimiyalelo, kunye nokuvumela okuthile kwindibano yokuchaza iinketho phambi kweengxoxo eziqhelekileyo (ukuba iPOSIXLY_CORRECT imo eguquguqukayo isetiwe, eyenza ukusebenza okwahlukileyo kwi-BSD). Ukongeza, kuba ifilosofi yeGNU isebenzisa ulwazi oluvela kumaphepha omntu (kwaye isebenzisa izixhobo ezinje ngolwazi), ulwazi olunikiweyo lukhulu.
Iimpawu ezintsha eziphambili ze-GNU Coreutils 9.2
Kolu guqulelo lutsha lwe-GNU Coreutils 9.2, kugxininiswe ukuba ukhetho "-base64" (-b) yongezwa kusetyenziso lwe-cksum ukuprinta kunye nokuqinisekisa i-base64-encoded checksums, kunye nayo yongezwe "-eluhlaza" ukhetho lokubonisa itshekhim kuphela eyoqobo ngaphandle kokuchaza igama lefayile kunye nolunye ulwazi.
Olunye utshintsho olwenziwe kolu guqulelo lutsha kukuba ukhetho "-debug" yongezwe kwi-cp, mv kunye nokufaka izinto eziluncedo ukubonisa ulwazi oluneenkcukacha malunga nendlela yokukopa ifayile.
Ukongeza koku, sinokufumana kwakhona kwi-GNU Coreutils 9.2 ukuba yongezwe "-ixesha=uhlengahlengiso" ukhetho kusetyenziso lwe-ls ukubonisa kunye nokusebenzisa xa uodola amaxesha olungiso lwefayile, kunye nokongeza ukhetho “-akukho-kopi” kusetyenziso lwe-mv ukwenza imposiso isiphumo xa uzama ukukopa ifayile phakathi kweendlela ezahlukeneyo zefayile.
Kumsebenzi wokwahlula, kwiinketho '-n SIZE', ubungakanani ngoku bunokugqithisa uluhlu lwamaxabiso apheleleyo. Xa i-"split -n" icacisiwe, kuvunyelwe ukufumana idatha kumbhobho ongachazwanga ngegama kunye nobukhulu bedatha enikeziweyo, ngokubonga kwi-staging kwifayile yesikhashana.
Kukwaphawulwe ukuba inkxaso yokhetho “-itotali={okuzenzekelayo,akunakuze,kuhlale,kuphela}” ukuya into eluncedo wc ukulawula ukuba isishwankathelo kufuneka siboniswe nini.
Kwelinye icala, usetyenziso tee iphumeza ukusetyenzwa kwemveliso engathinteliyo, umzekelo, xa imveliso kwi-terminal esuka kwi-telnet okanye i-mpirun idluliswa nge-tee.
Inkxaso eyongeziweyo kwizimaphambili zobungakanani obutsha: Ronna (R) - 10 27 , Quetta (Q) - 10 30 , Ri - 2 90 , kunye neQi - 2 100, ngelixa "cp -sparse=auto", "mv" e-install uses i-copy_file_range system call yokwandisa ukuphathwa kweefayile ezinendawo ezingenanto.
Kwicala le ukulungisa iibhagi, oku kulandelayo kukhankanyiwe:
- cp, mv kwaye ufake ngoku ngokukhawuleza zibone iimpazamo ezidlulayo xa usenza ikopi-ekubhaleni okanye ifayile ye-reflink, ukuxhasa iinkqubo zefayile ezifana ne-XFS, BTRFS, APFS, njl.
- cp, mv kwaye ufake ngoku phatha ukusilela kwe-ENOENT kwiinkqubo zefayile ze-CIFS, ubuya umva ukusuka kwi-copy_file_range ukuya kwikopi esemgangathweni exhaswa ngcono.
- 'mv –backup=i-fd elula/' ayisayi kubuyisela impazamo kwi-d/f ukuya ku-f~.
- rm ngoku ayiphumelelanga ngokuchanekileyo xa uphelelwa yinkumbulo.
- rm -d (–dir) ngoku iphatha ngokuchanekileyo abalawuli abangenanto abangafundekiyo. Umzekelo, ngaphambili, oku kuya kusilela ukususa d: mkdir -m0 d; src/rm-dd
- I-runcon -compute ayisajongi umyalelo ochaziweyo kwi- $ PATH ngoko kungabikho kungangqinelani phakathi kwefayile ehloliweyo kwaye yenziwe.
- 'Sort -g' ayisaphumi xa inikwa ii-NaN ezininzi kumaqonga afana no-x86_64 apho 'ubude obuphindwe kabini' bunamasuntswana okhupho kwinkumbulo.
- I-stty ispeed kunye neenketho ze-ospeed azisamkelwa kwaye zithe cwaka zityeshela iimpikiswano zesantya ezingasebenziyo, okanye zinike izilumkiso ezingeyonyani zezantya ezisebenzayo. Ngoku ziqinisekiswa ngokuchasene neseti eyamkelwe ngokubanzi, kwaye inkqubo ixhasa iseti yezantya ezisebenzayo
