Wizards and GUIs (for the most part) only allow the user to perform operations that the developers have anticipated. The beauty of interacting with the computer through the command line -- the shell or some other programmable interface -- is that you can do things that no one else has thought of before. You can write any program that is expressible in the language you use or string together the input and output of any program on your machine. Buttons are nice, but sometimes you just need to be more expressive than that. When this mode of interaction is necessary, I find that the Unix way has a lot to offer.
