UkuBhalwa kweShell - Isifundo 03: Konke malunga nokuBhala ngeBash Shell
Ukuqhubela phambili uthotho lwethu lwezifundo kwi Ukushicilela kweShell, namhlanje sinikela eyesithathu (03 Tutorial) Ngokufanayo.
Kwaye kuba, kwi-2 yokuqala siyalungisa iziseko landela, Izikhululo, iiConsoles, iiShell kunye neBash Shell, Kule yesithathu, siya kugxila ngokukodwa ekwazini yonke into enokwenzeka malunga neefayile ezibizwa Scripts kunye nobuchule be Ukushicilela kweShell.
UkuBhalwa kweShell – Isifundo 02: Konke malunga neBash Shell
Kwaye ngaphambi kokuba uqale oku Isifundo 03 kwi "Shell Scripting", sincoma ukuhlola oku kulandelayo imixholo enxulumeneyo, ekupheleni kokufunda le post namhlanje:
Isifundo sokuBhalwa kweShell 03
Iifayile zeSikripthi kunye noLwimi lokuBhala lweShell
Xa ndinonikwa i, iShell ibonelela ngobume benkqubo eyomeleleyo ngaphezulu kwe-GNU/Linux, Ukuze uyisebenzise kakuhle, kuya kufuneka ukwazi ukuyisebenzisa kakuhle iifayile zescript kunye nobuchule be iqokobhe lolwimi loshicilelo.
Ukuqonda zombini iikhonsepthi ngolu hlobo lulandelayo:
Izikripthi
Izikripthi unyana iinkqubo ezincinci ezenziwe kulo naliphi na iqokobhe, nayo ekungeyomfuneko ukuba iqulunqwe. Ukusukela, iqokobhe elisetyenzisiweyo lizakutolika umgca ngomgca. Oko kukuthi, Ushicilelo yifayile ezenzekelayo, idla ngokudalwa kwi ifayile yokubhaliweyo eqhelekileyo enemiyalelo yemveli nefundekayo yomyalelo. Kungenxa yoko le nto banikela a icocekile kwaye icacile isivakalisi, ebenza babe yindawo entle yokuqalisa ukuqalisa kwihlabathi lenkqubo kwi-GNU/Linux.
Ngenxa yoko, kunye Izikripthi okanye iifayile zeShell Scripts singenza inkqubo ukusuka imiyalelo emincinci nelula kwimisebenzi ethile, efana nokufumana umhla wenkqubo nge-terminal; de ubaleke imisebenzi emikhulu kunye nephambili okanye uluhlu lwemiyalelo ezinjengokuqhuba ukugcinwa kwenkxaso eyongeziweyo yeeFayile/iiFolda okanye iDathabase kwinethiwekhi.
Iqokobhe lokuBhala
Ngokuqhelekileyo ichazwa njenge Ukushicilela kweShell la ubuchule bokuyila kunye nokuvelisa iScript yeShell yenkqubo ethile yokusebenza. Kwaye oku, zisetyenziswa ngokuqhelekileyo Abahleli Besiqendu Esilula (GUI/CLI). evumela a ukuphathwa lula kunye ngqo ikhowudi kunye nokuqonda kakuhle isintaksi yenkqubo esetyenzisiweyo.
Ngoko ke, i Ukushicilela kweShell, ngokusisiseko ivumela ulawulo lwe uhlobo lolwimi lwenkqubo olutolikwayo. Ekubeni, ngelixa inkqubo eqhelekileyo kufuneka iqulunqwe, oko kukuthi, iguqulelwe ngokusisigxina kwikhowudi ethile ngaphambi kokuba iphunyezwe; UkuBhalwa kweShell kusivumela ukuba senze i inkqubo (ShellScript) ehlala ikwimo yayo yokuqala (phantse rhoqo).
Ngamafutshane, I-Shell Scripting iyakuvumela:
- Yenza iinkqubo kunye nemisebenzi ngeekhowudi ezilula nezincinci.
- Lawula iifayile zekhowudi yemvelaphi njengombhalo ongenanto.
- Sebenzisana namacandelo abhalwe ngezinye iilwimi zokucwangcisa.
- Sebenzisa iitoliki endaweni yabaqulunqi ukuqhuba iinkqubo.
- Yenza iinkqubo ngendlela elula, elula kwaye efanelekileyo, nangona ixabiso eliphezulu lokucwangcisa.
Kwinqaku elizayo, siza kuhlolisisa kancinane ngakumbi malunga neziBhalo kunye neShell Scripting.
Isishwankathelo
Ngamafutshane, ngale nto Isifundo 03 kwi "Shell Scripting" Siyaqhubeka nokubonelela ngomxholo obalulekileyo kwi isiseko sethiyori kolu luhlu lwezithuba, kule ndawo yobugcisa yokulawula i GNU/Linux Terminal.
Ukuba uwuthandile umxholo, phawula kwaye wabelane ngayo. Kwaye khumbula, ndwendwela ekuqaleni kwethu «webhsayithi», ukongeza kwijelo elisemthethweni le yocingo ngeendaba ezininzi, izifundo kunye nohlaziyo lweLinux.
