Perhaps you have a collection of digital photos from your camera, or maybe you are working with files created on an old Microsoft Windows or MS-DOS system that are all uppercase, and you want to give them more readable file names.
Changing the names of a few files by hand may be manageable, but changing more than a dozen files quickly becomes not only tedious but error-prone. Linux does have some tools that will rename files in bulk.
