I've done something very similar once, but it makes them all lowercase.
I wrote it in Ruby for a friend. I've attached it to this message. Just
run it in the target directory. So...

cd /home/tuna/frightened_horse_sounds/
ruby uppercasefile.rb

It'll go through ever file there and make it lowercase. Make sure that
you don't have any existing files called lol.txt there. :)
