I always searched an easy way to suspend and resume processes (useful to save resources without quitting programs). First, add the following lines in your .profile

pause () { kill -SIGSTOP `pidof "$*"`;}
resume () { kill -SIGCONT `pidof "$*"`;}

then add the following shell script to your PATH

#!/bin/sh
ps axc|awk "{if (\$5==\"$1\") print \$1}"|tr '\n' ' '

and make it executable. To pause a process, from the terminal, type

pause iTunes

Remember to change the name of the process. To resume it, use

resume iTunes
