What? What? A GUI is "punishment"? I will take a moment and grok that.

All right, all right, yes, after a fashion, it is punishment.

Hey I've been using a shell. But as I recall, when my geekiness reached a
certain pinnacle, and I typed "ls" into the command line and pressed enter,
I nver saw "usr". But if it is preceded by a period, even "ls" would not
show it, right?

OK, Nemesis, please clarify: is "usr" typically the name of this root
folder, parent to all other directories?

Well, in my ignorance, I have scouted around the internet, and I read one
convincing piece which said basically, don't do anything as Root if you can
avoid it. One could inadvertently do all kinds of terrible things.

Your remarks make things much clearer. Thank you!
