I’ll never forget seeing someone type the pipe symbol, | . I was like, “How did you do that and what does it do?!” For those who need to know, the pipe symbol is located above the enter key on most keyboard and it used to join commands in *nix to make magic happen.
Anyways, if you are new to *nix, I would suggest looking around and try to make things work, break them and then fix them. This is the best way to learn IMO.
