Hi monks, I have a script which forks a child and exec's another program. The parent script then generates signals to the running child exec. My question is, how can I get a stdout line from the child immediatly in the parent script? And how do I tell in the parent script when the child has finished? I want to do something like this: 
my $child = fork;
if (!$child)
{
  exec('someprogram.exe');
  exit;
}
else
{
  while (child_process_still_running())
  {
   sleep 1;
   system('kill -USR1 $child'); #signal child
   get_new_std_out_lines_child_has_printed_inresponse_to_signal();
  }
}
