Welcome to the other side. I highly recommend checking man pages when looking up commands to start getting a feel for how to use them, also I recommend getting tealdeer (TLDR, get it?) It’s a TLDR of man pages that shows you how a package is usually used. I’ve often found that it bridges a syntax gap that is often missed in man pages.

Learning how to navigate and use man pages saved my ass when I was screwing around with my network.
