Write a script that counts how many times a user tries to quit the program with an interrupt (typically Control-C), showing the count and finally letting them quit on the fifth attempt. Tip: You'll need to use trap for this and the interrupt signal is SIGINT

Question

What will be an ideal response?

Answer 1

count=0

trap 'interrupt' 2

interrupt()
{
echo "I won't quit. Count = $count"
count=$(( ${count} + 1 ))

if [ $count -eq 5 ] ; then
echo "Enough! I'll quit, I'll quit."
exit 1
fi
}

echo "Use Control-C to try and quit this script."

sleep 9999
