You can't. You need to imitate the "system()" call (see perlipc for sample code) and then have a signal handler for the INT signal that passes the signal on to the subprocess. Or you can check for it: $rc = system($cmd); if ($rc & 127) { die "signal death" } -------------------------------------------------------------------- The perlfaq-workers, a group of volunteers, maintain the perlfaq.
