See:
man killpg
The try this little script:
-- cut --
#!/bin/bash
sleep 15 &
sleep 15 &
sleep 15 &
sleep 15 &
sleep 15 &
# kill 0
-- cut --
After running it, immediately type:
ps fx
This will show all of the sleep commands still running.
Remove the `#' from the kill command at the end... then run
the script again, following with the ps command. All of the
sleep commands will be gone... because they are terminated
as part of the "process group".
A brief referenced is made to `kill 0' in the bash man page
at the beginning of the "SIGNALS" section.
