Type "jobs" to see a list of things running in the background. To bring one to the foreground, type "fg" followed by one of the numbers you see in the jobs list. Example: 

# jobs
[1]-  Running                 sleep 15 &
[2]+  Running                 sleep 20 &
# fg 2
sleep 20
[1]-  Done                    sleep 15

EDIT: After you're done with something in the foreground and you want to go back to the background, type ctrl-z to stop it, then bg to restart it in the background.
