@elena I'll check my archives to see what I have, my old coursework could be nice too If I can get my hands on it again

@elena To learn being comfortable with CLI in linux, you could try a manual install of linux. Arch Linux used to require it and had a really solid wiki.

If you do want to try this I'd recommend doing this in a VM you will miss things the first two/three tries, and a VM is really nice for practice.

@elena I mean as far as programming goes, I'd recommend starting to learn with C

It will teach you HOW things work under the hood, and once you're good with that, you can move out to other languages. The difficulty curve can be steep depending on the person. But it's imho the best way to start.

If you want to jump into things faster, python is widely used to introduce kids to programming these days.

As for your goals, I don't think they are directly related to programming. Those are more in the domain of a sysadmin
