Why Change File Names in Linux?

Before we dive into the different ways to change file names in Linux, let’s consider some of the reasons why you might need to do so. Here are a few examples:

• Renaming files to make them more readable: If you have a large number of files with similar names, renaming them to make them more readable can be a good idea.
