Jack, would it make sense to show the equivalent way to get the same info via the system applets/GUIs? That would have two benefits -- it would help the new users who will never really use the command line, but do want a technical understanding; and it'll avoid snarky comments from people who don't seem willing to understand that having multiple ways to do things is good, and the command line is an efficient alternative.

Understood that would be a challenge, because the different desktop environments use slightly different GUIs (just like Windows and MacOS use different GUIs, and didn't choose to standardize). You could probably get away with just providing a list of links for the major desktop envs/distros.
