Well be dammed. I 'learned' that when I first got into Linux back 14 years ago or so. I would have sworn I read that in the Journal or a man page or a book. But you are correct. alias policy='apt-cache policy $1' or alias policy="apt-cache policy " or alias policy='apt-cache policy ' all do work the same! Never to old to learn I guess. Now I have to go back and find just where I got that info to start with! Thanks Wesley, for the bash lesson! :-) Wayne -- Hardware: The parts of a computer system that can be kicked. _______________________________________________________ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
