confirmed exit using trap

I am trying to trap the Ctrl+C signal asking a confirmati开发者_如何学编程on from the user. The trapping part works fine. But once the signal gets trapped and the user presses NO, it does not return to the normal execution. Instead, it quits the script. How to make it resume execution when the user presses no?

Here is my code:

hell()
{
    echo "Do you want to quit? Press 1 for yes and 0 for no";
    read n;
    if [ $n == 1 ]; then
    exit 1;
    fi
}

trap "hell" SIGINT

find /

The problem here is the INT signal is being received by your script AND by your command find /, so it exits.

You can fully ignore the signal(s) with:

trap '' SIGNINT

I don't know if it's possible to catch the signal and prevent that your commands receive it.
