Isetshenziselwa ukubuka, ukusetha kabusha, noma izinguquko mathupha ngaphakathi kwe-bash path hash. Igcina izindawo zezinhlelo ezisanda kwenziwa futhi izibonise noma nini lapho sifuna ukuyibona.
Iluphi uhlobo lwe-hash olusetshenziswa yi-Linux?
Ku-Linux ama-password okungena ngemvume avame ukusheshiswa futhi agcinwe kufayela /etc/shadow kusetshenziswa i-algorithm ye-MD5. Ukuvikeleka komsebenzi we-MD5 hashi kufakwe ebucayini kakhulu ubungozi bokushayisana.
Ngiyithola kanjani i-hash yefayela ku-Linux?
Kafushane: Lo mhlahlandlela wabaqalayo uyakutshela ukuthi i-checksum ihlola ini, ukuthi ayini amasheke e-MD5, SHA-256 kanye ne-SHA-1, kungani kusetshenziswa amasheke kanye nokuthi ungawaqinisekisa kanjani amasheke ku-Linux.
...
Qinisekisa amasheke ngomugqa womyalo we-Linux
- Ithuluzi lokuhlola le-MD5 libizwa nge-md5sum.
- Ithuluzi lokuhlola le-SHA-1 libizwa nge-sha1sum.
- Ithuluzi lokuhlola le-SHA-256 libizwa nge-sha256sum.

Ubala kanjani inombolo yezimpikiswano ezidluliselwe kuskripthi segobolondo?
Ungathola inani lama-agumenti kupharamitha ekhethekile $# . Inani lika-0 lisho “akukho mpikiswano”. I-$# eyokufunda kuphela. Uma isetshenziswa ngokuhambisana ne-shift yokucubungula i-agumenti, ipharamitha ekhethekile engu-$# iyancipha isikhathi ngasinye lapho kukhishwa i-Bash Builtin shift.
Iyini i-bash Linux?

Ithini incazelo ku-Linux?
Kuhla lwemibhalo lwamanje kunefayela elibizwa ngokuthi “mean.” Sebenzisa lelo fayela. Uma lokhu kuwumyalelo wonke, ifayela lizokwenziwa. Uma kungukuphikisana komunye umyalo, lowo myalo uzosebenzisa ifayela. Isibonelo: rm -f ./mean.
Imuphi umyalo obeka iskripthi ukulala?
I-Linux Sleep Command (Misa Isikhashana Isikripthi Se-Bash) ukulala kuwumugqa womyalo okuvumela ukuthi umise inqubo yokushaya isikhathi esithile. Ngamanye amazwi, umyalo wokulala umisa ukukhishwa komyalo olandelayo ngenani elinikeziwe lamasekhondi.
Isetshenziswa kuphi i-hash algorithm?
Imisebenzi ye-Cryptographic hash isetshenziswa kakhulu ku-IT. Singawasebenzisela amasiginesha edijithali, amakhodi okuqinisekisa umlayezo (ama-MAC), nezinye izinhlobo zokuqinisekisa.
