Since you seem to be on a *n*x machine, seems like this would be a lot simpler (assuming a bash shell):
$ find /tmp/rja/find_test -type f -print0 |
perl -0 -ne 'chomp;
$t=do{local $/; open(T,"<",$_);<T>};
print "$_ is completely CRLF\n" unless ( $t =~ /(?<!\r)\n/ )'
But then, I've never been a fan of File::Find, ever. It's just too weird and too slow.
BTW, are you looking for files that are completely CRLF, as I assumed in my snippet, or rather for files that have any CRLF in them? If the latter, the last part of the snippet would be if ( $t =~ /\r\n/ ) update: and I'd change "is completely" to "has".
