And that is why I love Perl! I'd give you my whole days worth of ++ if I had more left. A pure work of art!

Hi NetWallah.

That is absolutely amazing.

As I am part of the below average person group you will have to help me with one further question.

I managed to capture the output through running the command on Explorer^2's DOS Command line option.

I pasted the output into a text file and all my checks so far on your output after running the code on a 2600 line input file have found the output to be 100% correct.

However, I need to capture the output in a more easy way.

How do I insert this code into a .pl file? Do I need 'if ($line =~ ........' etc.

If you can give me some idea on that it will help me so much for this particular program and many more in the future.

Many, many, many thanks.

#!perl
use strict;

my $infile  = $ARGV[0];
my $outfile = $ARGV[1];
unless (@ARGV==2) { 
  die "Usage : perl $0 infile outfile\n" };
open IN, '<',$infile 
  or die "Could not open $infile : $!\n";
open OUT,'>',$outfile 
  or die "Could not open $outfile : $!\n";

my @hdr; my $count_in; my $count_out;
while (<IN>){
  ++$count_in;
  my @f = split;
  if (@f<3){
    @hdr = @f;
  } else {
    print OUT "@hdr $_";
    ++$count_out;
  }
}
print "$count_in lines read from $infile\n";
print "$count_out lines written to $outfile\n";
close IN;
close OUT;

Hi poj.

Thank you for your assistance.

You guys/gals are advanced here.

I replaced the  my $infile = $ARGV[0]; with  my $infile = C:\Users\... \abc.txt;

Similar with the output file.

I knew it was not right to do this but I did not know what else to do.

How do I get my input file read in and the output into the output file?

Again, thank you very much for the code and assistance.
