How can you change the filename in a Linux system?

In Linux, the mv command (move) is used to change the name of a file. It moves a file or folder, but if you specify a new name in the same directory, it effectively renames it.

Example:

mv old_filename new_filename

If the file is in the current directory, just specify the old and new names. If you want to rename and move it, specify the new path with the name.
