From their original post.

I’ve been using Linux daily for over a year now and I still have a hard time tracking down config files and install paths.

To which you responded, with commands which are not guaranteed to do the former, only the latter, without making clear those limitations.

Your original advice is useful when paired with some clarification of its limitations, though given what the other person asked, it's insufficient advice. However by not making clear your advice's inability to in some cases do what the other person asked for, what you gave amounts to invalid advice because you've sent the other person down a dead end without making them aware that might be the case.

Then to add insult to injury, down the thread you repeatedly wrote that this is what they "wanted", which was obviously not the case as was very clear from the very start (it wasn't even what they asked for) and couldn't have been made clearer in the rest of the thread as the other person repeatedly said it was not what they wanted and even proved it.

The only reason I eventually intervened is because in a professional context I've had to correct lots of junior techies doing the exact kind of mistake you just did, though it's rare for even a fucking junior developer on their very first job to dig such a deep hole of insisting again, and again (and again, AND AGAIN) they know better than the person seeking advice what they actually WANT whilst giving them invalid advice, as you just did.

I mean, thanks for giving the advice and do keep on doing so, just learn to review your own internal assumptions about what they want if it starts to look like there's a mismatch between what you gave them based on your initial assumption and what they seem to need, especially if they themselves are telling you that's not what they want (and that person actually went extremelly far in trying to clarify things, even giving you the output of the command in their system to prove it didn't do what they want - non techie and/or low patience users would've given up on you far earlier than that person did).

Mind you, if you don't work in Tech and don't plan on doing so, feel free to ignore my post.
