I'm not against using Google, stack exhange, man pages, apropos, tldr, etc. but if you're trying to advertise competence with a skillset but you can't do the basics and frankly it is still essentially a mystery to you then youre just being dishonest. Sure use all tools available to you though because that's a good thing to do.

Just because someone breathed air in the same space occasionally over the years where a tool exists does not mean that they can honestly say that those are years of experience with it on a resume or whatever.
