how to make a non-interactive bash kill its children

[Irek Szczesniak]

I run a script, and so Bash runs non-interactively.  In the script I 
run some commands with:

> some_command &

My script is run by a process which doesn't have a controlling 
terminal, and so my script doesn't inherit the terminal.

I want Bash to kill the commands that I run when my script exits.  The 
option "huponexit" doesn't work for me because Bash runs 
non-interactively.  How can I achieve my goal?

Thanks for reading.


Best,
