Trapping a killed process

[AQWQ]

Am executing an application thru a shell script say S.sh and the executed application becomes the child of S.sh process.The exact thing i need is if i kill the parent process the child shud get killed automatically.Any idea??

Thanks in advance. Santhosh Ravindran

Trapit () # trap function
{
echo "Script aborted!... \c"
echo "Cleaning up... \c"
kill %1
kill -9 $$
}

trap Trapit 1 2 15 # cleanup if script is aborted
# the numbers signify different signals
# don't believe a trap will work if someone
# does a kill -9 against your script

# do your regular code here

# try doing a ctrl-c and see what happens.

# you can modify the actins in the function

# kill %1 would kill the first job
# if you ran a child script in the background.
# kill -9 would kill the parent script.

hope this helps,
