Oh it actually does. Making it specific doesn't change anything:

When I am asking: "Whenever I eat pizza in the morning, it tastes metallic to me. Has anyone an idea why that could be?"

I dont want someone to answer: "Why are you eating pizza for breakfast?"

This answer is worth nothing. Actually its even worse, cause answering it costs time.

Worth nothing to the asker. But stack exchange is a two-way communications platform, and responders (and other readers) may want to know more context.

I, for one, am still curious why OP is running a test where they call `man` with no input and fail on different stderr.

Of course it doesn't, when your "specific" analogy isn't nearly analogous to the situation.

I actually agree with him, it's a perfect analogy.

Calling man in a test and expecting the output to match some particular value is a much weirder thing to do with man than eating pizza in the morning.

It is honestly a lot more likely that the reason man is outputting ‘gimme gimme gimme’ at a particular time of day is something to do with your crazy test setup than that it is a feature of man.

So for the pizza analogy, think of it more as ‘pizza sometimes tastes metallic to me when I cook it under the hood of my car’. The car situation seems likely to be relevant. It would be surprising, when someone asks a question like that, to discover that it’s actually because the frozen pizzas they buy when they drive to the parking lot where they then cook them under their car hood actually contain iron filings that were put there deliberately by the manufacturer.
