How To Find A String In a Directory of Files Using Linux

All Uniq based operating systems contain a massively powerful command line interface that can let you do a lot of really cool things that you may not have realized. If you are looking for a piece of text in a huge directory of files, there is no need to go through each file and check. You can run a very simple command that will perform the search for you.

The following code will allow you to find a string inside a directory of files using any Linux/Unix based operating system using the Grep command. To make this command work correctly, make sure you are inside the directory that you wish to search.

If you wish to perform this command on a different directory that you are not currently inside, use the following command.

This will search for all files that contain ‘mystring’ inside the /var/myfolder directory. The -r argument will make this recursive so that it will also search all subdirectories. If you just want to search the top level directory, remove this -r command.
