Just saying “terminal bad, GUI good” tends to result in the sort of GUI where someone thinks the job is done if they put a button for every command-line switch. (AcidRip is an egregious example.)

But then, this is an example of how there’s no substitute for good design. And a reason good designers get paid a lot.

In providing support on a forum, answering with a few lines that can be cut’n’pasted into a terminal is often quicker than giving directions through a GUI … often quite a bad GUI.
