You may also use regex with locate: locate -r regex_expression Using updatedb to create your own index for locate command Keep in mind that the result may show all the files that have the search term in their name.

In this tutorial, you'll learn how locate command works and how to use it. When you use the command, it refers to this index instead of searching the entire filesystem.
