I-chmod I-Command kwi-Linux

Shintsha iimvume zefayili ukusuka kumgca we-Linux umyalelo

Umyalelo we-chmod (indlela yokutshintsha intsingiselo) kukuvumela utshintshe imvume yokufikelela yeefayili kunye neefolda.

Umyalelo we-chmod, njengeminye imilayezo, unokukwenziwa ukusuka kumgca womyalelo okanye ngefayili yeskripthi.

Ukuba ufuna ukuluhlu lweemvume zefayili, ungasebenzisa umyalelo we-ls .

i-chmod Command Syntax

Le yile syntax eyiyo xa usebenzisa umyalelo we-chmod:

chmod [iindlela] kwimodi [, imodeli] ifayile1 [ifayile2 ...]

• -f, - isil, i-quiet (inqumla imilayezo emininzi yempazamo)
• -v, --verbose (iziphumo zokuxilonga zonke iifayile ezenziwe)
• -c, --shintsha (njengeverbose kodwa iingxelo kuphela xa utshintsho)
• -R, - ngokubanzi (tshintsha iifayile kunye neenkcukacha ngokuphindaphindiweyo)

Ngezantsi uludwe lweemvume ezininzi zamanani ezingasetyenziselwa umsebenzisi, iqela kunye nabanye abantu kwikhompyutha. Emva kombolo yifunde / ibhala / yenza ibhalana elilinganayo.

Imizekelo yokuLawula i-chmod

Ukuba, ngokomzekelo, ufuna ukutshintsha iimvume zefayili "abathathi-nxaxheba" ukuze wonke umntu abe nokufikelela ngokupheleleyo, uza kungena:

nxaxheba 777

I-7 yokuqala ibeka iimvume zomsebenzisi, okwesibini ibeka iimvume zeqela, kwaye isithathu yesithathu ibeka iimvume zabanye abantu.

Ukuba ufuna ukuba yedwa onokuyifumana, uya kusebenzisa:

nxaxheba kuma-chmod 700

Ukuzinikela kunye namalungu eqela lakho ukufikelela okupheleleyo:

abathathi-chmod 770

Ukuba ufuna ukugcina ukufikelela ngokupheleleyo, kodwa ufuna ukugcina abanye abantu ekuguquleni ifayile, unokusebenzisa:

nxaxheba 755

Oku kulandelayo isebenzisa iileta ezivela phezulu ukuze utshintshe iimvume zabathathi-nxaxheba ukuze umninimzi afunde nokubhala kwifayili, kodwa ayitshintshi iimvume kwabanye abantu:

chmod u = participants

Ulwazi olungakumbi malunga nomyalelo we-chmod

Ungatshintsha ubunikazi beqela leefayile kunye neefolda ezikhoyo ngomyalelo we-chgrp. Tshintsha iqela elizenzakalelayo kwiifayile ezintsha kunye neefolda ngomyalelo we-newgrp.

Khumbula ukuba izikhonkwane ezingumqondiso ezisetyenziswe kumyalelo we-chmod ziya kuthintela into eyinyani, ekujoliswe kuyo.
