Ungalususa kanjani uhla lwemibhalo ku-Linux?

Ohlelweni lwe-Linux, ukususa uhla lwemibhalo kungenziwa ngezindlela ezahlukahlukene, kuye ngokuthi ufuna ukugcina uhla lwemibhalo ngokwalo kanye nezici zefayela ngaphakathi kwalo. Ngezansi kunezindlela ezimbalwa ezivamile:

Indlela yoku-1: Sebenzisa i- rm umyalo wokususa wonke amafayela ngaphakathi kohlu lwemibhalo

Uma ufuna ukususa wonke amafayela kuhla lwemibhalo kodwa ugcine uhla lwemibhalo ngokwalo, ungasebenzisa i rm umyalo. Isibonelo, ukusula uhla lwemibhalo oluqanjwe uhlu_lwami, ungasebenzisa umyalo olandelayo:

rm -rf my_directory/*

Indlela yesi-2: Sebenzisa umyalo wokuthola nge -exec

Uma ufuna ukulawula okuyimbudumbudu okwengeziwe phezu kwenqubo yokususa, ungasebenzisa itholaumyalo kanye ne-eqeinketho. Ngokwesibonelo:

thola my_directory -type f -exec rm {} \;



Lo myalo uzothola wonke amafayela (-uhlobo f) ngaphansi kwe uhlu_lwami directory bese ukhiphe ifayela le rm umyalo kufayela ngalinye.

Indlela yesi-3: Dala Uhla Lwemibhalo Olusha Ukuze Umiselele Olokuqala

Uma ufuna ukuthulula ngokuphelele uhla lwemibhalo futhi ungakhathazeki ngokulwenza kabusha, ungasusa lonke uhla lwemibhalo bese uludala futhi:

rm -rf my_directory mkdir my_directory

Le ndlela isusa uhla lwemibhalo nakho konke okuqukethwe kulo, bese idala uhla lwemibhalo olusha olungenalutho.




Indlela yesi-4: Sebenzisa i- rsync Umyalo

I rsync umyalo ungasetshenziswa ukuvumelanisa amafayela nezinkomba, futhi ungasetshenziswa ukuthulula uhla lwemibhalo. Ngokwesibonelo:

rsync -a --delete empty_directory/my_directory/

Lapha, okungenalutho_kwemibhalo iwuhlu lwemibhalo olungenalutho, kanye ne- --susa inketho isusa amafayela ohlwini lwemibhalo oluqondiwe angekho kumkhombandlela womthombo.



Izinyathelo zokuzivikela

Ngaphambi kokwenza imisebenzi yokususa, qiniseka ukuthi ngempela uhlose ukususa amafayela, njengoba lezi zenzo zingenakuhlehliswa.
Uma uhla lwemibhalo luqukethe amafayela abalulekile, yenza ikhophi yasenqolobaneni kuqala.
Ukusebenzisa i- sudo umyalo udinga amalungelo okuphatha. Uma ungenazo izimvume ezanele, kungase kudingeke ukuthi usebenzise sudo ukwenza le miyalo.
Izindlela ezingenhla zisebenza ezimweni eziningi, kodwa lapho uzisebenzisa, khetha indlela efanelekile ngokusekelwe esimweni sakho esithile, futhi uqhubeke ngokuqapha ukuze ugweme ukulahleka kwedatha.
