Verifying you have your environment and search paths setup correctly.

Don't actually display the manual page, but do print the location of the source nroff file that would be formatted.

Why would you even ask such a question to begin with? You say curiosity, but there seems to be more to it?

Asking why to a part of code or workflow is a good thing, even only because of curiosity. After knowing it, you may find the reasoning brilliant, or ridiculous and dismiss it and that's it.

However if any chance you have the same situation as OP, it may come out valuable, either currently or in the future.

I would have asked the same question for the same reason. A sibling comment introduced me to a feature that I wasn't familiar with. And that's why I'll continue asking curious questions until the day I die.

Why would there be more to it? I wanted to ask the same question, just because I simply did not know the answer. In fact, I am curious how you became so wary about such a simple, uncomplicated and direct question.

It was meant as joke, question the questioneer, for an honorary -4.
