I am definitely noob

I work in a sort of sequence, all the way to the disc drive. To the plug on my PC. Lol. Idk.
You may have to get a book, and start with learning about Unix, bin/sh, bash(born again shell) or stick to a certain environment(shell(Gnome,Unity, Gnome Classic, Mate, Explorer, Cinnamon, KDE,etc...) and stay there, coping with whatever comes along.
Or install #!.
If you can use #!, you can probably deal with whatever.
Even using DosBox for a few days, installing abandonware, will get you places...It really depends..for me it all starts to blend together, but I am painfully behind on subjects like servers which makes me a loser in the Linux world, lol.
