Renaming files in Perl is a common task, whether you need to modify filenames, move files to different directories, or simply organize your file system. Fortunately, Perl provides several methods to accomplish this task efficiently.

Using the rename Function:

In this example:

Replace "old_filename" with the current name of the file you want to rename.

Replace "new_filename" with the new name you want to assign to the file.

The or die statement is used to handle errors. If the renaming operation fails, it will print an error message containing the reason for the failure.

Here's a practical example:
