Hi
I was working on a shell script with randomly shows a page of text from a randomly selected topic .As soon as the page is displayed it callers a timer script which keeps on running indefinitely until the timer script is killed by the user.

This is where I have the problem,if I press Cntrl-C then even the parent script gets terminated.This is what my code looks like

cat ${file_nm} |head -$line_count | tail -100

timer.ksh

I tried modifying it to try the get the PID of the timer script and kill it like this below if the user enters 0 ,but even that doesn't seem to work

cat ${file_nm} |head -$line_count | tail -100

bg timer.ksh


PID=$$
echo $PID

read kill_proc
if [[ $kill_proc -eq 0 ]]
then

kill $PID
fi

I tried something like this but even this doesn't seem to work ,can you give me suggestions to just kill the timer script interactively which terminating the parent script as well

The timer script is just a simple infinite while loop

while true
do

sleep 1
done

Thanks for any help
