If I understand correctly what you are wanting to do .. this is how I would do it.

Have fun !!

-Kiel R Stirling

#!/usr/bin/perl -w use strict; use IO::File; my $output = pop @ARGV; my @merge; for my $file (@ARGV) { my $input_fh = IO::File->new($file); die "failed to open $file\n" unless defined $input_fh; $merge[$.-1] .= $_ while (defined ($_ = <$input_fh>) and chomp); $input_fh->close; } my $output_fh = IO::File->new("> $output"); die "failed to open $output\n" unless defined $output_fh; $" = "\n"; print $output_fh "@merge"; $output_fh->close;

./ file1 file2 file3 output_file

    That's exactly what I wanted, just tweaked it and it's perfect!

    Many Thanks Paul
