"nohup" and "&" commands
Why would anyone ever type in a command like this:

nohup command &



nohup lets you logout of your telnet session so why add "&" to run it in the background?

nohup causes a command to be immune to some signals. All versions of nohup include HUP. Some of them include QUIT. That is all that it does. If you do a "nohup command", from your command line, you aren't going to see another prompt until your command finishes. With a job control shell, you can move the foreground process into the background. But you are going to need a prompt if you want to log out in a conventional manner. So one way or another, you're going to need that command in the background.
