Ngilihlanganisa kanjani ifayela lakamuva?

Isebenza kanjani:

1. thola /var/log/folder -type f -printf '%T@ %p' Lokhu kubheka amafayela futhi kuphrinte isikhathi sawo sokulungiswa (imizuzwana) kulandelwe yisikhala negama lawo lilandelwa uhlamvu olungenalutho.
2. hlunga -rz. Lokhu kuhlunga idatha ehlukaniswe ngalutho.
3. sed -Ezn '1s/[^ ]* //p' ...

2. Izimpendulo eziningi lapha zihlaziya okukhiphayo kwe-ls noma sebenzisa i-find without -print0 okuyinkinga yokuphatha amagama-mafayela acasulayo.

Ngiwathola kanjani amafayela akamuva ku-Linux?

Usebenzisa umyalo we-ls, ungafaka uhlu lwamafayela anamuhla kuphela kufolda yakho yasekhaya ngale ndlela elandelayo, lapho:

1. -a - bhala wonke amafayela kuhlanganise namafayela afihliwe.
2. -l - inika amandla ifomethi yohlu olude.
3. -time-style=IFORMAT - ibonisa isikhathi ku-FORMAT eshiwo.
4. +%D – idethi yokubonisa/yokusebenzisa ngefomethi %m/%d/%y.

Ngiwathola kanjani amafayela akamuva ohlwini lwemibhalo?

thola . -thayipha i-f -exec izibalo -c '%Y %n' * : iphrinta isikhathi sokushintsha sokugcina silandelwe indlela yefayela yefayela ngalinye ohlwini lwamanje lwemibhalo; sort -nr : ihlunga ngokulandelana kwezinombolo eziphambene; awk 'NR==1,NR==3 {print $2}' : iphrinta inkambu yesibili yomugqa wokuqala, wesibili nowesithathu.

Ngiwathola kanjani amafayela okugcina ayi-10 ku-UNIX?

Ihambisana nomyalo wekhanda. I umyalo womsila, njengoba igama lisho, phrinta inombolo yokugcina engu-N yedatha yokokufaka okunikeziwe. Ngokuzenzakalelayo iphrinta imigqa yokugcina eyi-10 yamafayela ashiwo. Uma kunikezwe igama lefayela elingaphezu kwelilodwa khona-ke idatha evela kufayela ngalinye yandulelwa igama lefayela layo.

Ngisebenzisa kanjani ukuthola ku-Linux?

Umyalo wokuthola uthi esetshenziselwa ukusesha futhi uthole uhlu lwamafayela nezinkomba ngokusekelwe ezimeni ozicacisayo zamafayela afana nokuphikisana. Thola umyalo ungasetshenziswa ezimeni ezihlukahlukene njengokuthi ungathola amafayela ngezimvume, abasebenzisi, amaqembu, izinhlobo zamafayela, idethi, usayizi, nezinye izimo ezingaba khona.

Ngilikopisha kanjani ifayela lakamuva ku-Unix?

Running ls -t /path/to/source | ikhanda -1 izobuyisela ifayela elisha kuhla lwemibhalo /indlela/kuya/kumthombo ngakho cp “$(ls -t /path/to/source | head -1)”/path/to/target izokopisha ifayela elisha ukusuka emthonjeni kuya ekuqondisweni . Izingcaphuno ezizungeze inkulumo ziyadingeka ukuze kubhekwane namagama wamafayela aqukethe izikhala.

Ngisenza kanjani isitembu sesikhathi?

Ngiphakamisa ukuthi wenze:

1. Cindezela u-CTRL + ALT + T.
2. Qalisa umyalo ( -E ye-regex enwetshiwe): sudo grep -E '2019-03-19T09:3[6-9]'

Iyini i-Newermt ku-Unix?

i-newermt '2016-01-19' izoba ikunikeza wonke amafayela amasha kunosuku olushiwo futhi! izokhipha wonke amafayela amasha kunosuku olushiwo. Ngakho-ke umyalo ongenhla uzonikeza uhlu lwamafayela alungiswa ngo-2016-01-18.

Ngiwenza kanjani uhlu lwamafayela ayizolo ku-UNIX?

Ungasebenzisa umyalo wokuthola ukuthola wonke amafayela ashintshiwe ngemva kwenani elithile lezinsuku. Qaphela ukuthi ukuze uthole amafayela alungisiwe ngaphambi kwamahora angu-24 adlule, kufanele uwasebenzise -isikhathi +1 esikhundleni se -mtime -1 . Lokhu kuzothola wonke amafayela eshintshiwe ngemva kwedethi ethile.

Ngilifaka kanjani ifayela ku-Linux?

Ungawusebenzisa kanjani umyalo we-grep ku-Linux

1. I-Grep Command Syntax: grep [izinketho] PATTERN [IFILE...] ...
2. Izibonelo zokusebenzisa i-'grep'
3. grep foo /file/name. …
4. grep -i "foo" /file/name. …
5. grep 'iphutha 123' /file/name. …

7. grep -w “foo” /file/name. …
8. egrep -w 'word1|word2' /file/name.

Ngiwenza kanjani uhlu lwamafayela ku-Linux?

Bona izibonelo ezilandelayo:

1. Ukufaka ohlwini wonke amafayela ohlwini lwemibhalo lwamanje, thayipha okulandelayo: ls -a Lokhu kuklelisa wonke amafayela, kuhlanganisa. ichashazi (.)…
2. Ukuze ubonise imininingwane enemininingwane, thayipha okulandelayo: ls -l chap1 .profile. …
3. Ukuze ubonise ulwazi oluningiliziwe mayelana nohla lwemibhalo, thayipha okulandelayo: ls -d -l .

Ngiwathola kanjani amafayela amadala ku-UNIX?

I-%p ibeka igama lefayela. Umyalo wokuhlunga wawuhlunga okokufaka futhi wakudlulisele ukuthi uye kukho bonisa ifayela elidala kunawo wonke ohlelweni lwami lwe-GNU/Linux. Umyalo wokuhlunga wawuhlela okokufaka futhi wawudlulisela ekhanda ukuze ubonise ifayela elidala kunawo wonke ohlelweni lwami lwe-GNU/Linux.

Imuphi umyalo okuvumela ukuthi ubonise wonke amafayela kuhla lwemibhalo lwamanje ukuze amafayela amasha kakhulu afakwe ohlwini ekugcineni?

Incazelo : Inketho -a ikhombisa amafayela afihliwe, -l inika uhlu olude, -t ihlunga ngesikhathi sokuguqulwa okuthi ngokuzenzakalelayo ikhombise amafayela amasha kuqala, futhi -r ibuyisela ukuhlunga ukuze amafayela amasha abonakale ekugcineni.
