ari mvumo inyaya inonakidza nyaya muUnix world uye chimwe chezvinhu zvinokosheswa zvakanyanya zverudzi urwu rwekushandisa system. Linux inoshandisa ino sisitimu yemamodhi kune madhairekitori uye mafaera eiyo system, uye kuti isu tinogona kuzadzikisa nemamwe maratidziro ekuchengetedza senge akawedzeredzwa hunhu ayo mamwe mafaera masisitimu anoshandisa, kana mamwewo mamwe marudzi ezvekuchengetedza masisitimu akadai seanogona kuwana zvinyorwa zvinyorwa kana ACL.
Mune zvimwe zvinyorwa tataura nezve modhi kana mvumo, chero chaunoda kuvadaidza, uye zvirokwazvo unoziva kare kuti tinogona kuona mvumo iyo yedu madhairekitori uye mafaera nemirairo yakapusa ls -l, asi mune iyo koni inotiratidza fomu yetsamba sezvatinoziva kare. Kune rimwe divi, isu tinogona zvakare kushandisa iwoyu notation kana iyo octal imwe kugadzirisa aya mvumo tichishandisa chmod raira, sezvamunotoziva ... Asi chii chinoitika kana tichida kunyora mvumo mune octal fomu?
Zvakanaka, kuitira ona octal notation Tinogona kushandisa maitiro akasiyana, kunyangwe imwe yeakareruka iri kuburikidza nemutemo wekuraira:
stat /etc/passwd
Nemutemo wapfuura isu tichaona yakawanda ruzivo nezve iyi chaiyo faira, mune muenzaniso / etc / passwd. Asi kana isu tichingoda kuona iyo kana mvumo mune octal fomati, unogona kushandisa:
stat -c '%a' /etc/passwd
Pakati pe mafomati uye mukana Inowanikwa, iyo iwe yaunogona kuona ne man stat, kune zvakare% A yekuona fomati ine mavara, uye zvimwe zvakawanda zvingasarudzwa kusefa zvakazara zvobva zvaratidza chete mamwe eminda anowanikwa kana isu tisingataure chero chinhu. Semuenzaniso, kana isu tichida kuratidzwa nzira mbiri dzekuona mvumo kana modhi dzeUnix dzefaira kana dhairekitori, tinogona kushandisa uyu umwe murairo:
stat -c '%A %a' /etc/passwd
Uye saka isu tichawana zvese mune zvakajairwa kuburitsa ...
