A brief note on moving programs from foreground to background from the Linux prompt.
First, you can pause your program with a "Ctrl+Z". The 'paused' program number is displayed.
Then, you can restart your program, BUT in the background, with a "bg [program number]" command.
Then to move it to foreground, use "fg [program number]".
Neat, eh?
Oh, you can start programs directly to the background by appending an amperstand after the program name. E.g. "top&" will run top in the background - rather pointless, but it's only an example!
