By default, the grep command displays the name of files containing the search pattern as well as matched lines. This is quite logical, as that's what expected of this tool.

However, there might be cases wherein the requirement could be to get names of those files that do not contain the searched pattern. This is also possible with grep - the -L options lets you do this.

So, for example, to find all those text files in the current directory that does not contain the word "how", you can run the following command:. If you want, you can also force grep to mute any error messages it displays in the output. This can be done using the -s command line option. As clear from the example used in the previous point, the grep command doesn't do a recursive search by default.

To make sure your grep search is recursive, use the -d command-line option and pass the value 'recurse' to it. As we have already discussed, the -l command-line option of grep is used when you only want the tool to display filenames in the output.

For example:. Here's how you can verify that:. So the output of the cat command confirms the presence of a newline character between the file names. But as you might already know, the newline character can be part of a file name as well. Well, you'll be glad to know that grep provides a command-line option -Z that makes sure filenames are followed by a NULL character and not a newline.

In our second GREP command tutorial, you can find even more examples of how to use this Linux command. I have two files with content. I would like to use grep to find all matching rows of file1 content, and that matches file2 row of content and display.

I'm a linux novice and im using the grep function to search for the number 1. How do i go about specifing the search so it's just car1 and wheel1? Many Thanks. For what it is worth you may want to look into using the "strings" command for searching for strings in a binary, as it is explictly designed for that.

You need a better patern. Tis is a little bit tricky, as some choies onclude a space, a tab, or a EOL. Thank you! The recursive capabilities of the "grep" program helped me find the information I'd sought in no time.
