I am trying to get the exit status of the child process.
If the Child exitted abruptly, then the parent must exit too
Here is a sample code: 
$SIG{CHLD} =\&reaper;
my ($pid, $child_pid);
if ($pid = fork) {
  print "[In Parent] After Fork\n";
  #  $SIG{CHLD} =\&reaper;
} else {
  die "Unable to Fork: $!\n" unless(defined $pid);
  if ($child_pid = fork) {
     print "[In Child-Parent]\n";
     my $cmd = ` <COMMAND! GOES HERE>`;
     if ($? eq 0) {
       print "@err\n";
       print "[In Child-parent] Exitting\n";
       exit(1);
     }
#   $SIG{CHLD} =\&reaper_sub;
  } else {
    print "[In Child-Child]\n";
    my $cmd2 = `<COMMAND2 GOES HERE>`;
    if ($? eq 0) {
      print "Error in [Child]: Exitting\n";
      exit(1);
    }
 } #End of child-child
  print "[In Child] End of Child\n";
} #End of Child

How do I ensure that the parent quits if its child/grand children exit.

update (broquaint): added formatting + <code> tags
