Name:Change Case of item names script
Category:MacOS X

Someone might know how to do this in unix, but there is an easy way to change the case of files on a Mac.

You'll need your Applescript menu enabled. If it's not already up and running (one of the little menus in the right side of the menu bar) - go to /Applications/Applescript/Applescript Utility and turn on the "show script menu" option AND "show library scripts"

Now, select some items in the finder, go to the script menu -> FInder Scripts - > Change Case of Item Names. You'll be prompted to pick all caps or all lowercare, and walaa - renamed.
