Stop getting <defunct> PIDs - How?

[josel]

To allow our operators accessing OLD and NEW companies which
now reside in two different file systems, I wrote a simple script which runs as they log on

while true
do
trap "echo" 1 2 3 15
clear
echo "
Some menu options

"
read OPT
case "$OPT" in
1)
set filePro environment and run menu ;;
2)
set filePro environment and run menu ;;
0)
exit 1 ;;
esac
done

As you can see, operator will stay within this menu until
he/she presses 0 to exit.

This works fine but I am getting A LOT OF <defunct> PIDs.
Why is this? What am I doing wrong?

I am suspecting that they are simply closing their telnet
sessions using [X] on window and instead of exiting application
using X key and then 0 as mentioned above.

Any ideas?

Thanks;

Perhaps because your trap is ignoring all of the signals that the parent process would use to close it. Try changing that to trap &quot;exit&quot; 1 2 3 15, that way if they try and break out of it it will presumably just log them off. Annihilannic.
