Hey guys. I want to convert all the file names within a folder to the following: My First Movie.mov to my_first_movie.mov I know you can do this easily within automator with the "make web friendly" action. I have an automaor workflow that uses way to many programs to accomplish my goal, so I am trying to write as much as I can in applescript form. I would like to stay out of automator because I don't find it very dependable. Does anyone know how I would do this using applescript, or do you know a shell command to use within my script? I'm assuming you would just use the the line "do shell command...", but I'm not sure. Thanks Guys.
