![]() ![]() var/log/Xorg.0.log: (WW) warning, (EE) error, (NI) not implemented, (?) unknown. To find files by name and grep their contents use these commands as follows: $ find -type f -name '' -exec grep -H "" \ cat a file to show the 1st line and the grep queried value. This short note shows how to recursively find files by name and grep their contents for some word or pattern.Ĭool Tip: How to match multiple patterns with -OR-, -AND-, -NOT- operators using grep! Read more → Find Files by Name and Grep Contents in Linux grep -n would number every line (not an issue for ps output which doesnt have empty lines). If you use the find command to recursively search for some files and then pipe the result to the grep command, by doing this you will actually parse the file paths/names but not their contents. Grep -l -r -include "*.js" "FIRSTWORD" * | xargs grep -L "SECONDwORD"ĭc0fd654-37df-4420-8ba5-6046a9dbe406 grep -l -r -include "*.The Linux find command can be used for searching files and directories and performing subsequent operations on them. grep -l -r -include "*.js" "FIRSTWORD" * | xargs grep "SECONDwORD" Get the first matched files from grep command and get all the files don't contain some word, but input files for second grep comes from result files of first grep command. Grep -RH "cats" /home/adam/Desktop/TomAndJerry #absolute directoryĪ short introduction to symbolic links, for anyone reading this answer and confused by my reference to them: If you want to find all mentions of the word cat in the directory /home/adam/Desktop/TomAndJerryĪnd you're currently in the directory /home/adam/Desktop/WorldDominationPlotĪnd you want to capture the filename but not the line number of any instance of the string "cats", and you want the recursion to follow symbolic links if it finds them, you could run either of the following grep -RH "cats". So if you want to find all files containing Darth Vader in the current directory or any subdirectories and capture the filename and line number, but do not want the recursion to follow symbolic links, the command would be grep -rnH "Darth Vader". Since you're trying to grep recursively, the following options may also be useful to you: -H: outputs the filename with the line If you want to follow symbolic links as well as actual directories (be careful of infinite recursion), grep -R "thing to be found" directory If you only want to follow actual directories, and not symbolic links, grep -r "thingToBeFound" directory Vendor/klaussilveira/gitter/lib/Gitter/Client.php:176: return $this->hidden Vendor/klaussilveira/gitter/lib/Gitter/Client.php:170: * Get hidden repository list Vendor/klaussilveira/gitter/lib/Gitter/Client.php:20: protected $hidden Tests/InterfaceTest.php:32: $options = array(self::$tmpdir. Src/GitList/Provider/GitServiceProvider.php:21: $options = $app Src/GitList/Application.php:43: 'git.hidden' => $config->get('git', 'hidden') ? $config->get('git', 'hidden') : array(), I can get: /home/vonc/gitpoc/passenger/gitlist/github #grep -include="*.php" -nRHI "hidden" * This is equivalent to the -binary-files=without-match option.Īnd I can add ' i' ( -nRHIi), if I want case-insensitive results. Process a binary file as if it did not contain matching data Read all files under each directory, recursively this is equivalent to the -d recurse option. (Note: phuclv adds in the comments that -n decreases performance a lot so, so you might want to skip that option) -R, -r, -recursive Prefix each line of output with the line number within its input file. Recurse in directories only searching file matching PATTERN. That includes the following options: -include=PATTERN I cant show you here, but the output is neatly. The line number counter is reset for each file. H Always print filename headers with output lines -n, -line-number Each output line is preceded by its relative line number in the file, starting at line 1. (As noted by kronen in the comments, you can add 2>/dev/null to void permission denied outputs) You can tell grep to include the filename in the output. I now always use (even on Windows with GoW - Gnu on Windows): grep -include="*.xxx" -nRHI "my Text to grep" * ![]()
