Trapping SIGINT after restarting program.
Tried to add a function to my control_c interrupt here. It works but has one little bug. If the user selects to run the function instead of exiting, the program restarts itself without forking as it should. However, after that control_c no longer works again. I wanted to allow the user to run this function at anytime by pressing a button, so just running one time won't cut it. I searched Google and the Bash man page on 'exec' but couldn't find anything on this problem. Any advice much appreciated.

Code:
control_c()
{
   echo -e "Would you like to run this function?\n"
   echo -e "Enter y or n: "
   read ans

    if [ "$ans" == "y" ]; then

               # Do function here
               sleep 2
               exec bash test.sh
               exit 0
    else
               exit 0
    fi
}

trap control_c SIGINT

       files and/or presubj files) into package build directories.

FILES

       debian/package.bug-script
	   This is the script to be run by the bug reporting program for generating a bug report template. This file is installed as
	   usr/share/bug/package in the package build directory if no other types of bug reporting customization files are going to be installed
	   for the package in question. Otherwise, this file is installed as usr/share/bug/package/script. Finally, the installed script is given
	   execute permissions.

       debian/package.bug-control
	   It is the bug control file containing some directions for the bug reporting tool. This file is installed as
	   usr/share/bug/package/control in the package build directory.

       debian/package.bug-presubj
	   The contents of this file are displayed to the user by the bug reporting tool before allowing the user to write a bug report on the
	   package to the Debian Bug Tracking System. This file is installed as usr/share/bug/package/presubj in the package build directory.

OPTIONS

       -A, --all
	   Install debian/bug-* files to ALL packages acted on when respective debian/package.bug-* files do not exist. Normally, debian/bug-*
	   will be installed to the first package only.
