In my case I need to replace all punctuation marks with an underscore. I understand I could write multiple sed s commands for ".", "?" and "!". I was just wondering if there was a cleaner way to do it. For those who want to know this is for an Applescript for finding and editing iTunes tracks since iTunes automatically changes punctuation in the artist, album, and track name to an "_".
