Hi Monks, I have a script that spawns a few child processes each one to gzip a file. The problem is the command `gzip -9 $file1`; always returns -1 in the child process. There are not more than 10 child processes running at a time. I want to get the proper exit code for the gzip to make sure all the gzips went thru correctly. Please find my script attached and let me know what is going wrong. Thanks a lot. J 
#!/usr/bin/perl -w
my @gziplist = ( "msg.1","msg.2","msg.3","msg.4","msg.5","msg.6","msg.
+7","msg.8", "msg.9","msg.10");
 
my $pid;
my $file;
my @children;
my $dead =0;
$SIG{CHLD} = sub{$dead++; wait};

        $SIG{TERM} =
          sub{
                kill -9, @children;
                exit(0)
          }; # allow to end program by pressinc Ctrl-C or a kill call


LOOP:  for my $i ( 0..$#gziplist){
                $file = shift(@gziplist);
                if($pid = fork()){
                        push @children, $pid;
                        print " IN Parent spawned $pid  for $file\n \n
+ ";
                        next LOOP;
                }elsif(defined $pid){
                         `gzip -9 $file`;
                         print " \nIN child gzip for $file Command Res
+ult == $?\n ";
                         exit(0);
                }
        }

while($dead < 9){
}
