Isetyenziselwa iimbono, ukusetha kwakhona, okanye utshintsho ngesandla ngaphakathi kwe-hash yendlela ye-bash. Igcina iindawo zeenkqubo ezisanda kwenziwa kwaye izibonise nanini na xa sifuna ukuyibona.
Loluphi uhlobo lwehash olusetyenziswa yiLinux?
Kunikezelo lwe-Linux amagama ayimfihlo aqhele ukuheshwa kwaye agcinwe kwifayile /etc/shadow usebenzisa i-MD5 algorithm. Ukhuseleko lomsebenzi we-MD5 we-hash uye waphazamiseka kakhulu ngenxa yobuthathaka bokungqubana.
Ndiyifumana njani ihash yefayile kwiLinux?
Ngokufutshane: Esi sikhokelo sabaqalayo sikuxelela ukuba itshekhisum ijonga ntoni, yintoni i-MD5, SHA-256 kunye ne-SHA-1 itshekhi, kutheni kusetyenziswa iitshekhi kunye nendlela yokuqinisekisa iitshekhi kwiLinux.
...
Qinisekisa i-checksums nge-Linux ilayini yomyalelo
- Isixhobo sokutshekisha se-MD5 sibizwa ngokuba yi-md5sum.
- Isixhobo sokutshekisha se-SHA-1 sibizwa ngokuba yi-sha1sum.
- Isixhobo sokutshekisha se-SHA-256 sibizwa ngokuba yi-sha256sum.

Uyibala njani inani leengxoxo ezigqithiselweyo kwiqokobhe leskripthi?
Ungafumana inani leengxoxo kwiparameter ekhethekileyo $# . Ixabiso lika-0 lithetha "akukho mpikiswano". $# iyafundeka kuphela. Xa isetyenziswa ngokudityaniswa neshifti yoqhubekeko lwengxoxo, iparameter eyodwa $# iyacuthwa ngexesha ngalinye i-Bash Builtin shift isenziwa.
Yintoni i-bash Linux?
I-Bash liqokobhe le-Unix kunye nolwimi lomyalelo olubhalwe nguBrian Fox weProjekthi ye-GNU njengokutshintshwa kwesoftware yasimahla yeqokobhe leBourne. Ikhutshwe okokuqala ngo-1989, isetyenziswe njengeqokobhe lokungena elingagqibekanga kunikezelo oluninzi lweLinux. … I-Bash inokufunda kwaye iphumeze imiyalelo evela kwifayile, ebizwa ngokuba siscript seqokobhe.
Yeyiphi inguqulelo ye-bash endinayo?
Ukufumana inguqulelo yam ye-bash, sebenzisa nawuphi na umyalelo olandelayo: Fumana uguqulelo lwe-bash endiluqhubayo, chwetheza: echo “${BASH_VERSION}” Jonga inguqulelo yam ye-bash kwi-Linux ngokuqhuba: bash –version. Ukubonisa uguqulelo lweqokobhe le-bash cofa Ctrl + x Ctrl + v.
Ithini intsingiselo kwiLinux?
Kuluhlu lwangoku kukho ifayile ebizwa ngokuba yi "mean." Sebenzisa loo fayile. Ukuba lo ngumyalelo wonke, ifayile iya kuphunyezwa. Ukuba yimpikiswano komnye umyalelo, loo myalelo uya kusebenzisa ifayile. Umzekelo: rm -f ./mean.
Ngowuphi umyalelo obeka umbhalo ukuba ulale?
Umyalelo wokulala we-Linux (Misa iSikripthi se-Bash) ukulala sisixhobo somgca womyalelo okuvumela ukuba unqumamise inkqubo yokufowuna ngexesha elithile. Ngamanye amazwi, umyalelo wokulala unqumama ukuphunyezwa komyalelo olandelayo kwinani elinikiweyo lemizuzwana.
Isetyenziswa phi ialgorithm yehash?
Imisebenzi ye-Cryptographic hash isetyenziswa ngokubanzi kwi-IT. Sinokuzisebenzisela utyikityo lwedijithali, iikhowudi zoqinisekiso lomyalezo (MACs), kunye nezinye iindlela zokuqinisekisa.
