machine:~$ command &

...in bash, the & puts the command in the background, so you can 
continue doing things.  You can switch it back to the foreground with 
"fg %1".  You can have multiple jobs running in the background; first 
one started is %1, second one is %2, etcetera.

If you've put a process into the STOP state with Ctrl-Z or "kill -STOP", 
you can always resume it by doing "kill -CONT".  Note that this may not 
work properly if the process you stopped is a user-interactive process; 
I never could get slrn to work right after STOPping it.  (ncurses 
problem? Oh well...)
