I would not consider those "awesome answers".
They don't explain anything; they may let you get something done, but
they don't help you understand what you're doing, why you're doing it,
or why doing it that way works when doing it a different way wouldn't.
They may be enough for what you went looking for, but the larger goal of
any question should be to *learn* - if only so that you don't need to
ask a similar question later on, for a similar but not identical task -
rather than just to accomplish whatever task is currently at hand.
Answers like that don't help you learn.
(Unless you already know enough about the commands being used that you
can parse out the individual components and figure out what they do...
in which case you might well not have needed to ask the question in the
first place.)
