Hi, I need to add the values in column 1 together except for the last line, how can i ignore the last line in this context? 
open (COM, "2_info.txt");
      open (MEAN, ">" . "/2_mean_info.txt");
       foreach  (<COM>){

last LINE if /^d$/;??

if (/^\d+\.\d+.*/)
    {$value = (split /\|/, $_)[0];}

        $additive_GU_value += $value;
        $num_GU_processed++ ;
              
} # foreach
close (COM);

print "Add = $additive_GU_value\n";
