Dear all

I've recently come across a file, i think it's from a mac, which, on my RH9 box, shows it's line breaks as:

'^M'.

As a result of which, when trying to read in the file, it does NOT read in any lines, or so I believe.

has anyone come across this before?

Cheers
Sam

UPDATE:

The code belwo is basically what I'm using, and there's NO output. 

#!/usr/bin/perl -w
use strict;

my $file = $ARGV[0];

while(<$file>){
print $_;
}

the file looks a little like this, remember the linebreaks are '^M':
