Can you run "top" and see what's busy?

Hello! Just so you know, I am even newer than a newbie, so you'll have to talk to me like I'm five.

Yes, I'm at a shell prompt.

I tried logging in with my system name and password, but it came up as incorrect.

I typed in the "ps -ef" and this is what I got: ps: illegal option --f usage: ps [-aChjlmMrSTuvwx] [0|o fmt] [-p pid] [-t Hy] [-U user] [-N system] [-W swap] ps [-L]

Shutdown -h now works -- yea! I didn't know how to do that before.

Top brings up a bunch of stuff. Top line reads Processes: 5 total, 2 running, 3 sleeping.

I am also able to change directories and see that my folders and files are still there.
