Hi

can somebody give me some pointers as to how I do the following

I have a piece of code that consists of two loops 

while(<FILE1>)  {
        chomp;
        my @fields = split(/:/, $_);
        my $result = qx{ /opt/bin/target -e$fields[2] };
        print FILE2 "$fields[0]:$fields[1]:$result:NONBKID\n";
        foreach my $configParameter (keys %{$configHash}) {
          my $nbkid = $configHash->{$configParameter}{'nbkid'};
          my $ntid = $configHash->{$configParameter}{'ntid'};

          if ($ntid eq $fields[1]) {
                print FILE2 "$fields[0]:$fields[1]:$result:$nbkid\n";
          } 
        }
}

This produces an output file

What I wanted it to do was to either print the line with NONBKID in it or the line that matched the string compare but not both. e.g. The output should be 
ANY:spicejam:07F7817D470004327B471FC5327B050F:NONBKID
ANY:henders:07F7817D470004327B:nbhoijk
ANY:riffty:07F7817D470:nbaz94k
ANY:johbe:07F7817D470004327B471FC5327B050FE04379:NONBKID
.... etc

I'm not sure how to achieve this. The outside loop iterates through each record and then the inside loop also iterates through potentially hundreds of records looking for a match with the outside loop record. So I need a match in the inside loop to overwite the print from the outside loop if a match exists.

Any help would be appreciated
