Linux

So, I installed Linux Mint not too long ago, and while I've been able to do what I want to do without touching the Terminal, I am a bit curious how it works, and whether it could help me.

In particular, I am slowly getting into programming, and I've heard some people talk about strange, otherworldly things, like Vim, and Shell Scripts.

There was this PDF I downloaded called "The Linux Command Line" by William Shotts, but it is 570 pages long, and glancing through it, it seems to go into many different things, and I am afraid I'll end up learning a hundred things while only ever using ten of them, if you get my meaning.

So yeah, anyone who has some tips, or resources for a Linux newbie, please let me know.
