Ukucoca okusisiseko nge-grep

UAlexander (aka KZKG ^ Gaara)

11 Izimvo

Omnye wemiyalelo endiyisebenzisa kakhulu kwisiphelo sendlela ngu ukubamba, nangaphezulu koku cd o ls.

ukubamba Inokhetho oluninzi kwaye inikezela ngokungafaniyo, nangona kunjalo ndisebenzisa eyona ndlela iqhelekileyo, kodwa masiqale ngokuchaza Yintoni i-grep?

I-grep sisihluzi ngokulula, ngumyalelo obonisa imigca ehambelana nesihluzi esibhengezileyo.

Umzekelo, kwinkqubo yethu sinefayile / usr / share / doc / bash / I-FAQ kwaye umxholo wale fayile ngu:

Jonga umxholo wefayile

Ukuba ufuna ukudwelisa umxholo kwisiphelo sendlela ngomyalelo cat (ewe ikati, njengekati hehe) bangayenza:

cat /usr/share/doc/bash/FAQ

Ngoku, masithi sifuna ukudwelisa umgca wefayile leyo ethetha ngohlobo, kuba sisebenzisa i-grep:

cat /usr/share/doc/bash/FAQ | grep version

Ukubeka oko kwisiphelo sendlela kuya kukubonisa kuphela umgca oqulathe "uguqulelo" kule fayile, ayisayi kuphinda ibonise nawuphi na umgca ongenalo elo gama.

Kuthekani ukuba ndifuna ukubonisa yonke into ngaphandle komgca wenguqulo?

Oko kukuthi, ngendlela endikucacisele ngayo, yonke into ehambelana nesihluzi iya kuboniswa, ngoku ndiza kukubonisa indlela yokwenza yonke into ibonakale ngaphandle yintoni ehambelana nesihluzi:

cat /usr/share/doc/bash/FAQ | grep -v version

Uyawubona umahluko? ... ukongeza ngokulula -v Sele yenza umahluko 😀

Ke ukuba babeka ukubamba iya kukubonisa kuphela into ehambelana nefilitha, kodwa ukuba ubeka grep -v izakubonisa yonke into ngaphandle kwesihluzo.

Kulungile, apha iposti iphela, enye nje incam ngoku abanokuyicekisa kodwa ... abanalo nofifi lokuba iluncedo kangakanani i-grep

    Molo! .. .. ngokwenene ngumyalelo oluncedo kakhulu .. kwimeko yam ndiyisebenzisa kakhulu ..

    Umzekelo olula unokuba, umzekelo, dpkg -l | grep 'package' (kwimeko ye-distros esekwe kwi-debian), isetyenziselwa ukwazi ukuba siyifakile na loo phakheji.

    Kukhulu ukunika ezi zixhobo kuluntu lwethu luphela

      Ewe, i-grep inamandla njengombono wethu hahahaha, kunye ne-awk (kunye nokusika) baphumeza imimangaliso * - *

      Ndiza kufaka ezinye iingcebiso malunga nomsebenzi wesiphelo kungekudala

    Kulunge kakhulu!! Ewe grep yenye yezinto ezisindisa ubomi kuye nakubani na othanda ukusebenzisa i-terminal. Kuphela ngamagqabantshintshi: Awudingi ukusebenzisa umyalelo wekati konke konke. Ungabeka igama lefayile njenge grep parameter ngolu hlobo:

    Inguqulelo ye-grep / usr / isabelo / i-doc / bash / i-FAQ

    Kananjalo, nokuba ayinakukwazi, kuhlala kukho ukhetho lokuhambisa kwakhona ungeniso lomyalelo ngokwenza into enje:

    Inguqulelo ye-grep </ usr / share / doc / bash / FAQ

    Le yokugqibela inokwenziwa nangawuphi na umthetho, ke akukho mfuneko yokusebenzisa ikati ukuthumela ifayile kwigalelo lomyalelo.

    Sebenzisa i-redirect endaweni yekati kubangela ukuba iqokobhe lisungule inkqubo encinci, ngenxa yoko kusetyenziswa izixhobo ezimbalwa. Ayingumahluko oncomekayo, kodwa uthathwa ngokuba ulungile.

    Kwelinye icala, i-grep iba luncedo ngokwenyani xa usebenzisa amabinzana aqhelekileyo ... Ngaba kwanele ukongeza iposti entsha kwi-desktop ye-wordpress?

        Nge-grep unokwenza kwakhona izihluzi ezisisiseko esincinci, umzekelo:

        grep -B3 -A3 -E -i --color=auto -n "(desde|hacia)?linux(\.)?$" ~/miarchivo.txt

        Oku ngokusisiseko kubonisa imigca equlathe isigama esisilindeleyo (esinokuba kuyo nayiphi na indibaniselwano yoonobumba abakhulu nabancinci), kunye nemigca emithathu ngaphambi nasemva kwemithathu, iphakamisa iziphumo ngombala owahlukileyo, ibeka amanani emigca kwiziphumo, kwaye ivumela ukwenziwa kwamabinzana aqhelekileyo awandisiweyo kule meko avumele ukukhangelwa kwi "myfile.txt" kuyo yonke imigca ephela nge-desdelinux, hacialinux okanye i-plain linux (kunye okanye ngaphandle kwexesha).

        Ngendlela, amabinzana aqhelekileyo anikezela ngokuguquguquka okukhulu kwaye yonke "i-geek" elungileyo enomdla wesoftware yasimahla kufuneka ifunde ukuzisebenzisa, hehe.

    Kuyenzeka ukuba kusetyenziswe i-zgrep kwiipilisi ezikwi .ta.gz kuluncedo kakhulu xa sifuna ukuphonononga izingodo ezindala. Masinwabe

    Mholweni. enkosi ngeposi. Kwenzeka kum ukuba ukusebenzisa grep, igama endilibhalayo kwimigca ebonakalayo ayiguquki umbala. (ihlala inje) [umzekelo: grep ikati yefayile.txt]
    imigca kunye nekati ziyavela, kodwa ikati ayijiki umbala othile ukwahlulahlula
    (kwi-ccompus ye-uni yam iyabonakala)
    Ngaba uyazi ukuba ndingaluvula njani olu khetho?
