Guqula okubhaliweyo ngaphakathi kweefayile ngomyalelo omnye: perl

Ngamaxesha athile sifuna ukubuyisela isicatshulwa ngaphakathi kwifayile, umzekelo, tshintsha kwi Uxwebhu.txt yonke into ethi "usapho lwam" ithi "thina." Ukufezekisa oku sinokusebenzisa umhleli wethu wokubhaliweyo (uKate, Gedit, SublimeText, njl) kodwa kuhlala kulungile ukwazi okwahlukileyo, ezinye iindlela zokufezekisa iziphumo ezifanayo

Kuyenzeka ukuba nge amabinzana aqhelekileyo oku kunokufezekiswa, umyalelo we-sed umhle nje, unokwahluka okungapheliyo kunye nokukhetha kodwa ... kwabo bafuna ukubuyisela isicatshulwa kwi Indlela entsonkothileyo inokwenzeka, kubo kukuba ndizisa oku kwahluka kulula:

Ukulandela umzekelo, sinayo ifayile Uxwebhu.txt ibekwe ngaphakathi $ IKHAYA / Uxwebhu.txt ngalo mbhalo ulandelayo:

(...) usapho lwam Kufana nabo bonke, njengaye okanye ummelwane wakho. Inyaniso usapho lwam Sizama ukuba ngabantu abanoxanduva kwaye emehlweni oluntu, kwezopolitiko nakwezentlalo ezichanekileyo. Nangona kunjalo, endlwini yam kukho igusha emnyama, kwaye leyo yindima yam LOL!. Ndihleli ndingoyiki ukuthetha into ayicingayo (nokuba ayichanekanga emehlweni oluntu), nangona enyanisweni usapho lwam londliwe ubumdaka uluntu lwanamhlanje.

Ngalo myalelo ulandelayo uya kutshintsha «usapho lwam"ngo"kuthi":

perl -pi -e "s[mi familia][nosotros]g" $HOME/Documento.txt

Yinto elula 🙂

Ke isicatshulwa siya kuba:

(...) kuthi Kufana nabo bonke, njengaye okanye ummelwane wakho. Inyaniso kuthi Sizama ukuba ngabantu abanoxanduva kwaye emehlweni oluntu, kwezopolitiko nakwezentlalo ezichanekileyo. Nangona kunjalo, endlwini yam kukho igusha emnyama, kwaye leyo yindima yam LOL!. Ndihleli ndingoyiki ukuthetha into ayicingayo (nokuba ayichanekanga emehlweni oluntu), nangona enyanisweni usapho lwam londliwe ubumdaka uluntu lwanamhlanje.

Is syntax yile:

perl -pi -e "s[lo-que-quiero-cambiar][lo-nuevo-a-poner]g" archivo-en-el-cual-reemplazar

Umyalelo unokubonakala unzima, makhe siwuqhekeze kancinane kwaye sichaze ngokulula a

• perl Esiza kuyisebenzisa, perl
• -pi : Pí, njani π (ixabiso eliqikelelweyo lika-3.14)
• -e : U-E ucinga ukuba «e ukwenza» ..
• Ke kwizicatshulwa » sivula nge s kwaye sivale nge g: "sg" … Khawufan 'ucinge ngo-S woQalo kunye no-G woMdlalo ongaphaya 😀
• Jika phakathi kwe sg kufuneka sibeke iiseti ezimbini zebrakethi: [] y [], unjalo: "S [] [] g"
• Ngaphakathi kwizibiyeli zokuqala njengoko benditshilo apha ngasentla, isicatshulwa esifuna ukusisusa size sifake esitsha siza kuhamba, ngelixa kwiseti yesibini yeebakaki isicatshulwa esitsha oza kusibeka, silandela umzekelo: "S [usapho lwam] [thina] g"

Elula akunjalo?

Inkcazo ibanzi kakhulu kunento efunekayo kumyalelo, kulula ukuyiqonda 🙂

I-Perl ininzi kakhulu kunendlela yokutshintsha isicatshulwa, lulwimi olupheleleyo 😉

Ukuba ufuna ukufunda ngakumbi ngayo, faka ifayile ye package Perl-uxwebhu kwaye ujonge i-whooodo evumayo, yinto eyahlukileyo nje.

Ngendlela nangokuvala, ucinga ukuba ufuna ukufumana zonke iifayile ze-.

find $HOME/Documentos/ -name *.txt -exec perl -p -i -e "s[mi familia][nosotros]g" {} \;

Okanye usebenzisa ikhadi lasendle:

perl -p -i -e "s[mi familia][nosotros]g" $HOME/Documentos/*.txt

Ingxaki kolu luhlu lwesibini, kukuba ayizukutshintsha iifayile ezikwiifolda ezingaphantsi

Ngapha koko, ndiyathemba ukuba uyifumene inika umdla. Kum iluncedo kakhulu, sele ndinokutshintsha isicatshulwa ngqo kwi-terminal ... kakhulu! 😀
