Iilebheli, ukuyalela iilebheli kwi-Gnu / Linux ukwenza umsebenzi ube lula

Kwinqaku elilandelayo siza kujonga singazisebenzisa njani iilebheli kwisiphelo sendlela. Ukongeza ithegi kumyalelo we-Gnu / Linux kungenza kube lula ukuphinda usebenzise kwakhona. Ukuba unobunzima bokukhumbula imiyalelo entsonkothileyo okanye iindawo ezibalulekileyo kwifayile yefayile, iilebheli zinokuba luncedo olukhulu.

Iimpawu zinika abasebenzisi indlela elula yokudibanisa imitya ejongeka ngathi Iimpawu ze-hash (#HOME) ngemiyalelo esiyenzayo kwilayini yomyalelo. Nje ukuba ileyibhile isungulwe, sinokuwenza kwakhona umyalelo onxulumene noko ngaphandle kokuwuchwetheza kwakhona. Endaweni yoko, kuya kufuneka sibhale iilebheli. Umbono kukusebenzisa iilebheli ekulula ukuzikhumbula, kwimiyalelo enzima okanye enokuthi icaphukise ukuphinda uthayiphe.

Ngokungafaniyo nokuseta ii-alias, i iilebula zidityaniswa nembali yomyalelo. Ngesi sizathu, bahlala befumaneka kuphela ukuba uyaqhubeka nokuzisebenzisa. Nje ukuba uyeke ukusebenzisa ithegi, iya kuthi shwaka kancinci kwimbali yomyalelo. Uninzi lwabasebenzisi, oko kuthetha ukuba siya kuba nakho ukuchwetheza imiyalelo engama-500 okanye eli-1000 ngaphambi kokuba kwenzeke oku. Ke ngoko, iiteki ziyindlela elungileyo yokubuyisela imiyalelo eya kuba luncedo kangangexesha elithile, kodwa ingezizo ezo sifuna ukuba zibekho ngokusisigxina..

Qwalasela iilebheli ku-Ubuntu

Ukuqwalasela iilebula, kwi-terminal (Ctrl + Alt + T) kuya kufuneka sibhale umyalelo kwaye emva koko songeze iilebheli ekugqibeleni. Ithegi kufuneka iqale ngophawu # kwaye kufuneka ilandelwe kwangoko ngumtya woonobumba. Oku kuthintela i-tag ekuphathweni njengenxalenye yomyalelo, endaweni yoko iphathwa njengengcaciso equkwe kwifayile yethu yeembali imiyalelo. Lo ngumzekelo olula, nangona ungaloncedo:

echo "Esto es un ejemplo de etiqueta" #TAG

Lo myalelo uthile unxulunyaniswe nethegi #TAG kwimbali yethu yomyalelo. Ngoku ukuba sisebenzisa umyalelo wembali, siya kuwufumana:

history | grep TAG

Emva koko sinako phinda wenze lo myalelo ngokuchwetheza !? ilandelwe yithegi:

!? #TAG

Eyona nto iluncedo koku yisebenzise xa umyalelo esifuna ukuwenza ngokuphindaphindiweyo unzima kangangokuba kunzima ukukhumbula okanye ukucaphukisa ukuthayipha. Umzekelo, ukudwelisa ezona fayile zihlaziyiweyo okanye izikhombisi, sinokuthi ngokomzekelo sisebenzise ithegi efana ne- #RECIENT kwaye siyidibanise nomyalelo we-ls ofanelekileyo. Lo myalelo ulandelayo udwelisa iifayile kulawulo lwethu lwasekhaya, nokuba sikweyiphi na inkqubo yefayile ngoku. Uluhlu luluhlu ngokulandelelana komhla, kwaye lubonisa kuphela iifayile ezintlanu ezisandula ukwenziwa okanye eziguqulweyo.

ls -ltr ~ | tail -5 #RECIENTE

Singaphinda sisebenzise imiyalelo enelebheli usebenzisa i-Ctrl + r (Bamba iqhosha le Ctrl kwaye ucinezele iqhosha 'r'emva koko ubhale iilebheli (umzekelo, # KUTSHANJE). Ngapha koko, ukuba usebenzisa i-tag enye kuphela, uchwetheza nje # emva kokubetha i-Ctrl-r, umyalelo kufuneka uvele ngokuzenzekelayo. Ulandelelwano lwe-Ctrl + r, njengakunye!?, Ukhangela imbali yethu yomyalelo ngentambo esiyibhalayo.

Iindawo zokumakisha

Abanye abasebenzisi basebenzisa Iimpawu zokukhumbula iindawo ezithile zefayile. Oku kuququzelela ukubuyela kwizikhombisi esisebenza kuzo, ngaphandle kokubhala umkhondo opheleleyo weendlela.

cd /var/www/html #LOCALHOST

Kulo mzekelo, njengoko kubonisiwe kumfanekiso odlulileyo, ngalo lonke ixesha sifuna ukuhambisa isikhombisi esihambelana #LOCALHOST, siya kuba nendlela ekhawulezayo yokwenza.

Kufuneka kuthiwe Iilebheli azidingi kufakwa koonobumba, nangona oku kwenza ukuba kube lula ukuziqonda. Kananjalo, akunakulindeleka ukuba zingqubane nemiyalelo okanye amagama efayile akwimbali yomyalelo.

Olunye uhlobo kwiilebheli

Ngelixa iilebheli zinokuba luncedo kakhulu, zikho ezinye iindlela zokwenza izinto ezifanayo esinokuzenza ngazo. Ukuze sikwazi ukuphinda imiyalelo ngendlela elula, nayo singababela i ogama limbi:

alias recientes=”ls -ltr ~ | tail -5”

Ukwenza imiyalelo emininzi kulula ukuyiphinda, singaziguqula zibe siskripthi. Ukuba sivula ifayile ye .sh ngalo myalelo ulandelayo:

sudo vim archivosActualizados.sh

Kwaye ngaphakathi sibeka le migca ilandelayo, sinokubona iziphumo ezifanayo ngokungathi sisebenzise ii-alias zangaphambili:

#!/bin/bash
echo “Most recently updated files:”
ls -ltr ~ | tail -5

Nathi sinako ukwenjenjalo lungisa imiyalelo yakutshanje ngokukhangela ngomyalelo wembali:

hitory | tail -20

Nje ukuba ibekho bhala nje! ilandelwe linani ngasekhohlo komyalelo ukuba sifuna ukuphinda (umzekelo; ! 8).
