That’s rather inconvenient, though. Wouldn’t it be easier if you had a nice OS X application that would let you minify your code right from your Mac? Enter Minimus, the app I just finished.
Minimus is a handy GUI frontend for the YUI Compressor. All you have to do is drag one or more files onto the dock icon, hit a button, and in seconds you will have minified copies.
It’s a free download, but if you like it, feel free to send me $5 or so with the in-app PayPal form.
