Sidee in uu soo bandhigo liiska dadka isticmaala ee Linux?

Mid ka mid ah sifooyinka of hababka qalliinka multi-user, taas oo ka mid ah Linux ah, waxaa suurtagal ah in ay isticmaalaan dad kala duwan. Sida caadiga ah, mid kasta oo iyaga ka mid bilowdo koonto gaar ah. In Linux, liiska dadka isticmaala waxaa laga daawan karaa iyadoo la isticmaalayo qolof ah by teeb isku xigxiga oo gaar ah oo characters. Tani waxay kala duwanaansho ah xalinta dhibaatada waa kuwa ugu fudud oo u baahan ma xirfadaha gaarka ah.

Yuu yahay user a nidaamka

Sidee in uu soo bandhigo liiska dadka isticmaala on Linux

Sidee, ka dibna, si ay u xaliyaan dhibaatada of baxeen xisaabaadka jira? In Linux, liiska dadka isticmaala bandhigay taliska (taas oo loo ogol yahay in ay isticmaalaan noocyo kala duwan oo goobaha):

# Cat / iwm / passwd

Maxaad u shaqeeyaan? Xaqiiqada ah in macluumaadka loo baahan yahay oo dhan ku jira faylka / iwm / passwd ah. isaga si toos ah iyo waxa loola jeedaa xisaabaadka dadka xiiseynaya. Ka dib markii dejinayso amarka bandhigayaa liiska xisaab Linux. liiska dadka isticmaala nidaamka noqon karaan kuwo ballaaran. Xogta ku saabsan xisaabaadka jira waxaa lagu soo bandhigaa line by line.

Sida laga yaabaa in ay ka soo muuqan shaashadda? line ninba wuxuu noqon doonaa midka ah si ay u soo socda:

xidid: xD634Jhs5jH32: 0: 0, xidid: / xididka: / bin / bashnewuser: Xv7Q641g89oKK: 1000: 100: Ivan Fedorov: / guriga / newuser: / bin / uted

transcript:

account (username): password (password kaydiyaa foomka lo): cabitaan (ID gaar ah): GID (ID kooxaha ugu weyn ee user): GECOS (macluumaad dheeraad ah): tusaha (directory user): qolof (turjumaan amarka la isticmaalay).

Sidee baan u aragto dhaqdhaqaaqa xisaabta,

amarka kor ku soo bandhigay liiska dhammaan dadka isticmaala ka diiwaan gashan nidaamka. Laakiin waxa haddii aad rabto in aad soo bandhigaan on liiska Linux ee dadka isticmaala in ay yihiin firfircoon hadda? Waxaad isticmaali kartaa amarka soo socda:

# kan

Teeb waxbarida, dadka ka arki kartaa liiska xisaab firfircoon nidaamka. Xaaladdan oo kale, liiska user Linux Waxa kale oo la sameeyaa line by line. Iyadoo mudnaanta maamulka, waxaad soo saari kartaa account firfircoon manipulations ah oo kala duwan. Sidaas, aad dadka ku siin karaan in ay helaan faylasha ama fayl gaar ah si ay u xaddido isticmaalka barnaamijyada qaarkood.
