I don't really intend to call out anyone, so please don't feel that way. Keep in mind what I'm trying to construe is someone who has a lot of broad (not deep) book knowledge, but who can't do even basic practical implementation.
If you can explain how to design a system and you can do it, but don't know the exact commands off the top of your head, my comment isn't describing you. I don't expect people to e.g. know awk like the back of their hand, or to write perfectly compiling code on their first try.
But even if you don't have perfect recall of the commands, it should be pretty clear whether or not you've ever opened an editor and done basic implementation. If the GUI is your thing that's fine. But your knowledge must have some practical foundation which demonstrates you can actually walk the walk.
