If you haven't really used Unix before, or even if you have. If you haven't used this thing before, you're totally screwed! To list your files, you press ls. What? Why the hell for? I don't get it. To get help, you type in man. MAN? Okay there. Like I said. I don't really get it.
There's this text editor called vi. Now this thing is totally off the wall. Or more likely, I don't know how to use it, and I'm screwing things up. But basically, you press vi, okay, and you're bringing up the file. You can't see it. There's two modes in it, the editing part and the adding text part. You get in, and you can't type text in. You have to press i first. And to get out of i, you have to press Esc. And once you escape, what do you do? The arrow keys are j,k,m, and l. The delete key is d. And you pretty much have to know exactly what you're entering in, because it sure as hell doesn't show up properly on the stupid Unix screen. To quit without saving you have to type in :q! An exclamation mark to quit? Very strange. I guess this stuff would make sense back in those days before they had arrow keys and delete keys. Which brings me to the next point.
Unix was developed in something like the early sixties. Back then, they probably DIDN'T have arrow keys, which is the reason for this crap. But it hasn't been updated really since then. It's had stuff added, and modified. Not consistently. Every version is kind of different. Hence the zillion shells. But I mean.....my god. Monolithic architecture at its worst or something. Unix is pretty much a cobbled together, beat up, falling apart, mixed up monolithic heterogenous mixed bag of crap! Why the hell are we still using it?
