I have a script that calls out to a number of other scripts via system(). When I Ctrl+C any of the child processes, I want the parent process to handle that SIGINT. The problem is that when I Ctrl+C one of the child processes, the child process gets killed and we return to the flow of control in the parent process -- which then moves on to the next system() call. Instead, I want the parent process to die. The hack way to do this is to set the appropriate signal handler in each of the child scripts: 
$SIG{'INT'} = sub { kill -9, getppid() };

which sends SIGKILL to the process's parent. But of course that doesn't scale: every time I create a new script, I'll have to add that handler in it. And if the parent process happens to not be the parent script -- e.g., if the parent process is a login shell -- that 'kill -9, getppid' has just killed my login shell. So what's the approach here, if I want the parent process to handle all the signals for its children?
