bg - Move job to background

Move job into background where it will continue to run until it needs input from standard input.

Example:-

xemacs myfile
Ctrl Z
bg

Run xemacs in foreground then press Ctrl Z to suspend and place it in the background so that terminal can be used while xemacs continues to run. A simpler way to do this would be:-

xemacs myfile &

but bg is useful to put a job into the background once it is running.
