Ndizidibanisa njani iifayile ezimbini kwikholamu kwi-Unix?
Inkcazo: Hamba ngefayile2 ( NR==FNR yinyani kuphela kwingxoxo yefayile yokuqala). Gcina ikholamu yesi-3 kwi-hash-array usebenzisa ikholam yesi-2 njengesitshixo: h[$2] = $3 . Emva koko uhambe ngefayile1 kwaye ukhuphe zonke iikholamu ezintathu $1,$2,$3, udibanisa ikholamu egciniweyo ehambelanayo ukusuka kwi-hash-array h[$2] .
Uzidibanisa njani iifayile ezimbini ngomgca kwi Unix?
Ukudibanisa iifayile ngelayini, ungasebenzisa umyalelo wokuncamathisela. Ngokungagqibekanga, imigca ehambelanayo yefayile nganye yahlulwe ngeethebhu. Lo myalelo ulingana othe tye nomyalelo wekati, oprinta umxholo weefayile ezimbini ngokuthe nkqo.

Fumana uxwebhu ofuna ukuludibanisa. Unokukhetha ukudibanisa uxwebhu olukhethiweyo kuxwebhu oluvuliweyo lwangoku okanye ukudibanisa amaxwebhu amabini kuxwebhu olutsha. Ukukhetha i uhlanganise ukhetho, cofa utolo ecaleni kwe Dibanisa iqhosha kwaye ukhethe ukhetho olufunekayo lokudibanisa. Nje ukuba kugqitywe, iifayile ziyadityaniswa.
Ngowuphi umyalelo osetyenziswayo ukudibanisa iifayile ezininzi kwi Unix?
The joyina umyalelo kwi UNIX lusetyenziso lwelayini yomyalelo yokudibanisa imigca yeefayile ezimbini kumhlaba oqhelekileyo.
Ndikhuphela njani iifayile ezininzi kwenye kwiLinux?

Ungathumela imveliso esemgangathweni kwifayile usebenzisa u-'>' umqhubi ukugcina imveliso kwidisk okanye kwinkqubo yefayile.
Ndizidibanisa njani iifayile ezimbini zeUnix ecaleni?
Ndizidibanisa njani iifayile ezimbini zeUnix ecaleni? Joyina umgca osuka kwifayile1 kunye nomgca ukusuka kwifayile2 ukuya kumgca omnye kwifayile yemveliso. Shicilela umgca kwifayile enye, umahluli, kunye nomgca osuka kwifayile elandelayo. (Umahluli omiselweyo yithebhu, t.)
Ndizidibanisa njani iifayile ezimbini zokubhaliweyo kwiLinux?
Thayipha umyalelo wekati ilandelwa yifayile okanye iifayile ofuna ukuzongeza ekupheleni kwefayile ekhoyo. Emva koko, chwetheza iisimboli ezimbini zemveliso yokwalathisa kwakhona ( >> ) ilandelwa ligama lefayile ekhoyo ofuna ukongeza kuyo.
Ndiyibona njani enye imigca kwi Unix?
Shicilela wonke omnye umgca:
Umyalelo ushicilela umgca wangoku, kwaye ngoko nangoko ifunde umgca olandelayo kwindawo yepateni. d umyalelo icima umgca okhoyo kwisithuba sepateni. Ngale ndlela, eminye imigca iyashicilelwa.
Uyiguqula njani imigca emininzi ibe yilayini enye kwi Unix?
Ukubeka ngokulula, uluvo lwale sed-liner enye kukuba: fakela umgca ngamnye kwisithuba sepateni, ekugqibeleni buyisela zonke iikhefu zomgca ngomtya onikiweyo.
- :a; – sichaza ileyibhile ebizwa ngokuba yi-a.
- N; – fakela umgca olandelayo kwindawo yepateni ye-sed.
- $! …
- s/n/REPLACEMENT/g – buyisela zonke izahlulo zemigca ngeREPLACEMENT enikiweyo.
Ndizidibanisa njani iifayile ezimbini ngokuthe tye kwi Unix?
kudla lusetyenziso lwelayini yomyalelo ye Unix esetyenziswa ukudibanisa iifayile ngokuthe tye (ukudibanisa okunxuseneyo) ngokukhupha iilayini eziquka iilayini ezihambelanayo ngokulandelelanayo kwifayile nganye ekhankanyiweyo, eyahlulwe zii tab, kwimveliso eqhelekileyo.
