If you trawl forums where newbies hang out (like I do), you'll often come across people yearning to learn Linux and asking things like: "Where can I learn about [insert some technology here]?" "Some technology" being anything ranging from the very basic stuff, like "the shell" or "the filesystem," to the quite advanced, like "systemd" or "Docker."
That, I think, is the wrong question to ask and, hence, tutorials often get the answer wrong and center on one tool and one tool alone.

A better question may be what are the best tools to carry out this specific task? The answer is usually whatever is easiest and most effective, regardless of whether you have to use four or 40 different tools to achieve your aim.
