🥇Ack ndiyabwino kuposa grep | Pulogalamu ya ProHoster

Ndikufuna ndikuuzeni za chinthu chimodzi chofufuzira chomwe chimapangitsa moyo kukhala wosalira zambiri. Ndikafika ku seva ndipo ndikufunika kuyang'ana chinachake, chinthu choyamba chimene ndimachita ndikuyang'ana ngati ack yaikidwa. Izi ndizofunikira kwambiri m'malo mwa grep, komanso kupeza ndi wc kumlingo wina. Bwanji osakhala grep? Ack ali ndi makonda abwino kwambiri m'bokosilo, zosankha zambiri zowerengeka ndi anthu, perl regex ndi config system. Ngati mukufuna (muyenera) kufufuza kudzera pa terminal, ndiye kuti muyenera kuyesa.

Basic Features

Ack ndiyobwerezabwereza, ndipo kulemba zosankha zochepa nthawi zonse ndi lingaliro labwino.

Tikhoza kugwiritsa ntchito mbendera -wkuwuza zofunikira kuti ziyang'ane chitsanzo cha chitsanzo chathu chozunguliridwa ndi malire a mawu (whitespace, slashes, etc.).

ack -w mysql

Ack imathandizira kusaka ndi mtundu wa fayilo. Mwachitsanzo, tiyeni tipeze mtundu wa module mumafayilo a json.

ack --json '"version":s+"d+.d+.d+"'

Mndandanda wathunthu wamafayilo othandizidwa ukhoza kuwonedwa pogwiritsa ntchito:

ack --help-types

Nthawi zambiri muyenera kuwerenga kangati mawu akuwonekera mu fayilo ya chipika, mwachitsanzo, kuti mumvetsetse kuchuluka kwa deta yomwe script idakonzedwa.

Titha kuwerengera zochitika osati mufayilo imodzi yokha, komanso pagulu. Tiyeni titsirize kusaka kwa liwu la mysql: kuwerengera kuchuluka kwa mawu (-Ndi) mu *.js mafayilo (--js), kupatula mafayilo omwe sanapezeke (-h) ndi kufotokoza mwachidule zotsatira.

# выведем на экран все вхождения
ack --js -w mysql
# считаем общую сумму вхождений

Ngati mukufuna zina zowonjezera pakufufuza kwanu, mutha kufunsa ack
kuwonetsa mizere mpaka (-B) ndipo pambuyo (-A) mwa mawu opezeka. Kuti muchite izi, muyenera kufotokoza pambuyo pa chisankho chiwerengero cha mizere yomwe ikuyenera kuwonetsedwa.

# 2 строки до 
ack --js --column -B 2 "query.once('" ./lib/

# 2 строки после 
ack --js --column -A 2 "query.once('" . /lib/

Ndipo ngati mukufuna zonse ziwiri, gwiritsani ntchito (-C)

ack --js --column -C 2 "query.once('" ./lib/

Ack ali ndi zosankha zothandiza --kuyamba-kuyambira и --njira-mapeto. Iwo amathandiza pamene
Deta imasungidwa osati pamzere umodzi, koma mumitundu yambiri.

Mwachitsanzo, pali fayilo yokhala ndi sql code

Tiyeni titengepo mayina a mgawo. Chiyambi cha chipikacho chidzakhala mzere woyambira ndi SELECT, ndipo mapeto adzakhala mzere kuyambira FROM.

ack --range-start ^SELECT --range-end ^FROM 'td+.' ./test.sql

Ngati mawu osaka ali ndi zilembo zapadera monga nthawi, mapologalamu, ndi ena, ndiye kuti musawathawe pogwiritsa ntchito, mutha kugwiritsa ntchito mwayiwu. -Q.

# Поиск с экранированием

Kukhazikika

Pulogalamuyi ili ndi fayilo yakeyake. Mungathe kukhala ndi makonzedwe apadziko lonse kwa wogwiritsa ntchito (~/.ackrc) ndi m'deralo kwa foda inayake (muyenera kupanga fayilo ya .ackrc mufoda).

Zambiri mwazosankha zomwe zalembedwa mu configs zitha kufotokozedwa pamanja zikaitanidwa. Tiyeni tione angapo a iwo.

Musanyalanyaze foda mukasaka
