Neman fayiloli ko nemo fayiloli akan tsarin Linux daga tasha na iya zama ɗan ƙalubale musamman ga sababbin sababbin. Koyaya, akwai kayan aikin layin umarni da yawa don gano fayiloli a cikin Linux.

A cikin wannan labarin, za mu sake nazarin kayan aikin layin umarni 5 don nemo, ganowa da bincika fayiloli cikin sauri akan tsarin Linux.

1. Nemo Umurni

Nemo umarni yana da ƙarfi, kayan aikin CLI da ake amfani da su don nema da gano fayilolin waɗanda sunayensu suka yi daidai da sauƙi mai sauƙi, a cikin tsarin shugabanci. Yin amfani da nemo abu ne mai sauƙi, duk abin da kuke buƙatar yi shine samar da wurin farawa (saman gadon sarauta) inda abubuwan bincike suke. Wannan na iya zama kundin adireshi na yanzu ko duk wani kundin adireshi inda kuke zargin an adana fayil ɗin da kuke nema.

Bayan farawa, za ku iya ƙayyade magana (wanda ya ƙunshi gwaji, ayyuka, zaɓuɓɓuka da masu aiki) wanda ke bayyana yadda ake daidaita fayiloli da abin da za a yi da fayilolin da aka daidaita.

Yana goyan bayan zaɓuɓɓuka da yawa don nemo fayiloli ta amfani da halaye kamar izini, masu amfani, ƙungiyoyi, nau'in fayil, kwanan wata, girman da sauran yuwuwar sharuɗɗan. Kuna iya koyan wasu misalai masu amfani da neman umarni a cikin labarai masu zuwa:

  1. 35 Misalai Masu Aiki na Linux Nemo Umarnin
  2. Hanyoyin Amfani da Umurnin 'nemo' don Neman Kudiddigar Kuɗi da Inganci
  3. Yadda ake Neman Fayiloli Tare da Izinin SUID da SGID a Linux
  4. Yadda ake amfani da Umurnin ‘nemo’ don Neman Sunayen Fayiloli da yawa (Extensions) a cikin Linux
  5. Yadda ake Nemo da Rarraba Fayiloli Dangane da Kwanan Wata da Lokaci na Gyara a Linux

2. Gano Umurni

gano umarnin wani abu ne da ake amfani da shi na CLI don bincika fayiloli da sauri da suna, kamar neman umarni. Koyaya, kusan yana da inganci da sauri idan aka kwatanta da takwaransa saboda, maimakon bincika tsarin fayil lokacin da mai amfani ya fara aikin neman fayil (hanyar nemo ayyukan), gano abubuwan da ke tattare da bayanan bayanai wanda ya ƙunshi ragowa da sassan fayiloli da su. hanyoyi masu dacewa akan tsarin fayil.

Ana iya shirya kuma sabunta wannan bayanan ta amfani da umarnin updatedb. Lura cewa gano wuri ba zai ba da rahoton fayilolin da aka ƙirƙira bayan sabunta bayanan kwanan nan na bayanan da suka dace ba.

3. Grep Command

Kodayake umarnin grep ba kayan aiki ba ne don bincika fayiloli kai tsaye (a maimakon haka ana amfani da shi don buga layin da suka dace daga fayiloli ɗaya ko fiye), zaku iya amfani da shi don gano fayiloli. Da ɗaukan cewa kun san jumla a cikin fayil(s) da kuke nema ko kuna neman fayil ɗin da ke ƙunshe da nau'ikan haruffa, grep zai iya taimaka muku lissafin duk fayilolin da ke ɗauke da takamaiman jumla.

Misali, idan kuna neman fayil ɗin README.md wanda ya ƙunshi jumlar An assortment, wanda kuke zargin ya zama wani wuri a cikin kundin adireshin gidanku, maiyuwa a ~/bin, zaku iya gano shi kamar yadda aka nuna.

  • -d - yana ƙayyadadden ƙayyadaddun abu
  • -f - yana saita filin da za'a buga

Kuna iya koyan wasu misalan amfani da umarnin grep masu amfani a cikin labarai masu zuwa:

  1. 12 Misalai Masu Aiki na Linux Grep Command
  2. 11 Ci gaban Linux Grep Umurnin Amfani da Misalai
  3. Yadda ake Nemo Takamammen Kebul ko Kalma a cikin Fayiloli da kundayen adireshi

4. Wane Umurni

wanne umarni ƙarami ne kuma madaidaiciyar mai amfani don gano binary na umarni; yana fitar da cikakkiyar hanyar umarni. Misali:

Wannan ke nan a yanzu! Idan mun rasa kowane kayan aiki/kayan aiki na Commandline don gano fayiloli da sauri akan tsarin Linux, sanar da mu ta hanyar sharhin da ke ƙasa. Kuna iya yin kowace tambaya game da wannan batu kuma.
