While I've been using Unix/Linux shells for seemingly ever, remotely at first with telnet, then with SSH, I have a fairly consumer point of view towards the entire stack: I know their components well enough to be able to use them in my every day work, and to debug them with the few problems I encounter. The nitty-gritty doesn't concern me, and I frankly don't care much. I rather learn other stuff in more depth. That said, I do muchly appreciate that I can afford this point of view, because everything's stable and user friendly enough that I don't have to care. Disclosure: I'm not an SRE
