This is a situation where I would argue that giving "exact" images of the output is not helpful, and I'm somebody who normally hates fruity presentations of info. Having the reader make their own associations allows it to be applicable across environments and develops what I'll go ahead and call "Rambo problem-solving", where you must get from point A to point B, even if that means you have to improvise or roll in the mud a little. You can't go off the beaten path with most GUIs, so being able to with a CLI is one of its most compelling uses. The reader needs to associate the command with the info, and not the presentation of it.
