Ungayifeza kanjani iSysAdmin Terminal esebenzisa iShell Scripting

El Isikripthi se-Shell, Kubhekiswa ku- ukwenziwa kwemiyalo eyinkimbinkimbi mayelana Isikhumulo se-GNU / Linux (Console), kuyasiza kakhulu ukwenza imisebenzi ejwayelekile futhi ebalulekile ngaphakathi kwe- Uhlelo Lokusebenza lwe-GNU / Linux, okusivumela ukuthi sisebenzise i-_ yethu Izinsizakusebenza nesikhathi.

Ngakho-ke, ukusetshenziswa kwayo kusuka esigungwini kusivumela ukuthi senze imiyalo eyinkimbinkimbi yemiyalo ngesandla noma ngokuzenzakalela ngemibhalo noma njengemizila ehleliwe ngaphakathi kokulayisha okuzenzakalelayo noma imisebenzi ehleliwe ngaphakathi koHlelo Lokusebenza. I-GNU / Linux. Futhi i-a Umsebenzisi Ophakathi, Okuthuthukile noma i-SysAdmin el ishejuli (yenza ngokuzenzakalela) imisebenzi, izexwayiso kanye / noma izaziso ku-Host (PC / Server) ongazigcina Amahora / Umsebenzi Ngokwenziwa ngesandla noma ubuso nobuso, kuyinto eyisisekelo futhi ebalulekile ekusebenzeni kahle komsebenzi wakho njengochwepheshe osezingeni eliphezulu.

Okulandelayo, sizokhombisa ukuthi a idatha (inani / ipharamitha) egcinwe phambilini ngokuguquguqukayo ngomyalo I-Bash Shell noma iyahambisana, ingakhonjiswa ekugcineni kwe-GNU / linux Operating System yakho, ngendlela ephathekayo nelula. Ngaphezu kokulungisa ukwaziswa kweTheminali.

Isinyathelo sokuqala: Hlela i-.bashrc yomsebenzisi yakho

Ngomhleli ozikhethele wona (vi, nano, njll.) Hlela ifayela le- ifayela le-.bashrc yomsebenzisi wakho okumele itholakale ngaphakathi kwekhaya elifanayo, okungukuthi, ngokwesibonelo: "/ Ikhaya / my_user".

Faka okuqukethwe kulayini ngamunye kulayini olandelayo nayo yonke leyo eyengeziwe ocabanga ukuthi ilula ukuyikhombisa umsebenzisi lapho wenza i-terminal yomsebenzisi:

Isinyathelo Sesithathu: Hlela impande .bashrc

Phuma bese ugcina. Qalisa futhi bese uhlangabezana nezinguquko. Kufanele ibukeke ifana nalena eboniswe ngezansi, ezithombeni ezilandelayo:

Isinyathelo Sesine (ngokuzithandela): Ama-aliases wokuShuna

Khumbula ukuthi ukusetshenziswa kwama-aliases ngaphakathi kwe- .bashrc Kungakusindisa nesikhathi esiningi sokubhala. Nqamula lawo eza ngokuzenzakalela ngaphakathi kwe-.bashrc, efana:

alias ls='ls $LS_OPTIONS'
<strong>alias ll='ls $LS_OPTIONS -l'
<strong>alias l='ls $LS_OPTIONS -lA'

alias rm='rm -i'

Futhi engeza leyo ocabanga ukuthi iyadingeka, njengoba iyimiyalo esetshenziswa njalo, njenge:

alias cc='clear'

Kubalulekile ukwazi okuningi ngendlela ozifundisa ngayo mayelana okuguqukayo, iziteketiso, .bashrc nolimi bash shell ngezinga eliphakeme kakhulu lesiginali. Okufanayo kungafinyelelwa lapho kuqala amaseshini akude nge-ssh, esingayibona ngokuhamba kwesikhathi kwezinye izincwadi ezizayo.
