If I use a program like putty to SSH into my box, how does it handle stuff like me doing apt-get update or something like that. Does it require that I remain connected through SSH until it is done, or can I immediately disconnect and it will continue the commands I have given. Or is there a way to do this.
Yes, install Red Hat's "screen" package, and read the man page.
Quick summary:
Run "screen" to create a new session. Start any program you like inside the session. Use "Ctrl-a d" to disconnect. Use "screen -r" to reconnect whenever you like, including the next time you log in. The jobs will run inside the screen session, oblivious to your disconnecting or logging out.
Screen can do a lot more than that, but that's the common case use. The man page is your friend.
