You need to do more debug printing.

Read a very short file with a few characters over just two lines for simplicity. print " " . ord($_) foreach split //, $linein; And do that both before and after the chomp.

Notice what's going on now?

open my $fh, '<', 'short.txt';
binmode $fh;
my $linein = <$fh>;
print " " . ord($_) foreach split //, $linein;
print "\n";
chomp $linein;
print " " . ord($_) foreach split //, $linein;
print "\n";
