It's not that tough, I've just always loved using the shell because you can do so much with so little text, I try to compact as much as I can in one line. This works well, and is just what I wanted, thanks so much!

What about the differences between du and ls? Do most people use the latter even though it's not a very simple output? Are there better ways of doing it? I ask because I'm always surprised by little neat tricks and tips people have here and there.
