Sometimes I just want to change all of those ".MP3" extensions to ".mp3", or change an underscore that persists across several directories full of similarly named files, or just change the name of every file on my hard drive to something completely unrecognizable. You can always use
sedand just pretend that everything looks right, but taking the extra step to make your
sed-soaked dreams a sharp and terrible reality requires just a bit more crazy. Luckily, I have that in spades.
