The bash(1) manpage will have more detail, but it's worth mentioning 
'fg' can be used on more than one background task.

Use 'jobs' to get a list of child processes running under the shell.  
It'll list their names and a number, e.g. [1] grep or whatever.

That number is useful because you can do stuff like 'kill %1', 'kill %2' 
to kill a child process, or use 'fg 1', 'fg 2', etc to foreground a 
particular job.

I personally tend to use screen(1) or multiple terminal windows, but the 
above is still useful.

Ben.

P.S. I can name at least half a dozen HUMBUGgers who swear by screen(1). 
It can do loads of stuff, like having multiple shells in one window, 
split screen, keyboard locking and loads of other things.  It really 
comes into its own when you're on a dumbterm or something similar -- 
it's like Linux virtual terminals, but even more useful.
