I've been a windows user forever, played with Ubuntu for a little bit years back, but I definitely don't know Linux well. The only times that I ever use Linux are in docker containers. I've spent years writing java, python, php, and only occasionally need to use a Linux shell. When I do, Google and stack overflow are good enough to get the job done. Sure, maybe in some domains it's incredibly useful, but to be a decent developer? Not at all.
