Ukudlala ngemibhobho kwiLinux: imizekelo ebonakalayo

Las imibhobho okanye imibhobho zezinye zezimanga zehlabathi zeLinux ezizuzwe njengeLinux. Ngabo unokwenza ubuninzi bezinto eziluncedo kwi-terminal ukudibanisa imiyalelo. Into ongenakuyenza ukuba azikho. Kodwa zisabangela ukubhideka kwabanye abasebenzisi abanamava amancinci okanye abasandula ukufika kwihlabathi * le-nix ukusuka kwenye inkqubo yokusebenza efana neMicrosoft yeWindows.

Ke ngoko, kwesi sifundo siza kudlala nabo ngokubonisa eminye imizekelo esebenzayo enokukunceda kwimihla ngemihla xa usebenza kwilayini yomyalelo. Uza kubona ukuba kulula kangakanani ukusebenzisa kwaye zinokuba negalelo kakhulu. Ke ndiyakukhuthaza ukuba uqhubeke ufunda kwaye ubone imizekelo ...

• "Khupha isiphumo" somyalelo. Ngale ndlela, ungasebenzisa ngaphezulu okanye ngaphantsi ukuze ube nakho ukuhambisa ulwazi oluphuma kuwo nawuphi na umyalelo. Umzekelo, iziphumo zoluhlu lweefayile kunye nemikhombandlela, okanye yeenkqubo eziphendula kwigama "iofisi":

ls -al | more

ps aux | grep office | less

• Bala inani lemigca Unemveliso yomyalelo okanye ifayile. Umzekelo, jonga imigca enefayile ye-example.txt enayo okanye inani leenkqubo ezisebenzayo (khumbula ukukhupha i-1, kuba umgca wokuqala yintloko) kunye nenani leefayile okanye imikhombandlela:

cat ejemplo.txt | wc -l
ps aux | wc -l
ls | wc -l

• Khangela umgca okanye igama elithileUmzekelo i-IP eqala nge-192.168 yenethiwekhi esebenzayo:

 
ifconfig | grep 192.168

• Khangela amaxabiso athile, umzekelo iimvume zeefayile kunye nemikhombandlela, kwaye ubonise ii-PIDs zeenkqubo ezihambelanayo nenkqubo:

 
ls -lR | grep rwx
ps aux -ef | grep systemd | awk '{ print $2 }'

• Cwangcisa imigca yefayile ngokulandelelana kwealfabhethi:

cat ejemplo.txt | sort 

• Bona imigca yokuqala okanye eyoku-10 yefayile, kodwa kuphela ezo zinelizwi elithile:

head /var/log/syslog | grep WARNING
tail -f /var/log/syslog | grep error
