What helps people get comfortable on the command line?

Step 1: Use a youtube tutorial for the basic commands. Don't worry, you'll forget about them soon enough. But doing them once, helps with muscle memory.

Step 2: When in need to do something, copy/paste from Q&A/forums various commands that they suggest for your problem. Your basic knowledge from step1 will come back as you do that.

After a few days, you'll be understanding what's going on and how the whole thing works in an abstract level.
