Is the wrapper script, zgrep (zutils) 1.3 Running zgrep -version | head -n 1 will reveal which one (if any) of them is the default: zgrep (gzip) 1.6 The latter is a c++ program and it supports the -r, -recursive option. It doesn't support the -r, -recursive switch. The former is just a wrapper script that calls gzip -cdfq. I have two versions on my system, zgrep from gzip and zgrep from zutils. To search recursively means to also traverse all sub-directories. The above command omitted all sub-directories. You may also want to check out ripgrep, a line-oriented search tool that recursively searches the current directory for a regex pattern that comes with some extra features, and is very fast.There's a lot of confusion here because there isn't just one zgrep. Find all files with a specific string recursively. Here, 7 is the line number on which the pattern we've searched for ( text) was found.įor more information and advanced usage, see the grep man page. home/logix/Documents/test/folder/file2.txt:7:text Grep -Rni -exclude-dir= 'text' ~/DocumentsĮxample output: /home/logix/Documents/test/folder/file1.js:7:text In that case, the command you'd need to use would be (this is a single command): Also, you want to show the line numbers ( -n), search recursively and also follow all symbolic links ( -R). Let's say you want to find all files containing the case-insensitive ( -i) text in the ~/Documents folder and its subfolders except for the Private and Personal subfolders ( -exclude-dir), and only search in the files that have the.

Let's take a look at an example which combines these command line flags. -exclude-dir=GLOB is used to exclude folders from being searched.-include=GLOB / -exclude=GLOB includes or excludes certain files.Depending on the number of files, this can slow down the search, so take this into consideration when using it -i performs the search case-insensitive (it's case-sensitive by default).When a match is found, besides the file path in which it was found, grep will also display the line number on which the pattern was found Grep has many options, but below I'll only list a few that you might find especially useful when trying to find all files containing specific text on Linux (besides those already mentioned above):

In each file, the text apple will be replaced with orange. The following command will recursively find all files with extension. This includes strings like texting for example, because it contains our search pattern, text. Here is how to find and replace text across multiple files recursively. This lists all the files in the current folder and subfolders containing text. To do this, you need to open the terminal, navigate to the folder where you want to perform the search, and run: Say you want to search for the word text (case-sensitive!) in all the files in the current directory and its subdirectories. Grep is a command-line utility which prints lines that match a given pattern, and should be installed by default. For this we'll use grep, a standard Unix program. This article explains how to find all files containing specific text on Linux.
