How to Use grep to Show Just Filenames on Linux 😃💻

Are you tired of sorting through a long list of grep results, trying to find the specific filenames you're looking for? Look no further! In this guide, we'll show you how to use grep to only display filenames on your Linux system, without the hassle of going through all the matches. Let's get started! 🚀

The Common Approach 🤔

The familiar one-liner command you might have been using is:

find . -iname "*.php" -exec grep -H myString {} \;

While this command effectively searches for the desired files and displays any matches along with their filenames, what if you only want to see the filenames without the actual matches? How can you achieve that? 🤷‍♂️

The Simple Solution 🎉

To obtain only the filenames and their paths, without the accompanying matches, you can use the -l (or --files-with-matches) option provided by grep. This option tells grep to only display filenames that contain the search pattern, without displaying the matching lines.

Here's how you can modify the previous command to achieve the desired result:

find . -iname "*.php" -exec grep -l myString {} \;

By replacing the -H option with -l, you're instructing grep to print only the filenames that match your search criteria.

That's all you need to do to simplify the output and focus solely on the filenames! 🎯

Taking It a Step Further 🚀

If you frequently perform this type of search, it might be helpful to create an alias or a shell function to save time and effort. For example, you could add the following line to your .bashrc or .zshrc file:

alias fgrep='grep -l'

With this alias in place, you can now use fgrep instead of grep -l to quickly display filenames without matches:

find . -iname "*.php" -exec fgrep myString {} \;

Feel free to customize the alias according to your preference.👌
