Hi Monks -

I wrote a simple script that allows the user to enter a pattern of letters, searches through a list of words in a file, and outputs any words that match the pattern (sort of like a crossword solver). Here's the code: 

#!/usr/bin/perl

use strict;

print "Enter word to be solved.\n";
print "Use a dash (-) to indicate a single missing letter.\n";
print "Use a star (*) to match 0 or more letters.\n";
print "Use a plus (+) to match 1 or more letters.\n";
print " WORD --> ";

chomp( my $word = <STDIN> );

$word =~ s/\-/\\w/g;
$word =~ s/\*/\\w*/g;
$word =~ s/\+/\\w+/g;

open WORDLIST, "< WORD.LST" || die "Cannot open WORD.LST: $!\n";

while (<WORDLIST>)
{
    chomp( my $newWord = $_ );
    if ( $newWord =~ m/^$word$/i )
    {
        print $newWord . "\n";
    }
}

close WORDLIST;

When I run the script on Windows (ActiveState Perl), it seems to work perfectly. However, when I run it under Cygwin I get no results, no matter what pattern I enter - even if I type the exact word.

My concern isn't as frivolous as it seems. I'm developing a much larger script for work that uses a good bit of RegEx pattern matching. It will eventually run on a Unix server, but I'm running it through Cygwin for alpha testing. I need to be sure I'm getting accurate results before I muck up the data on our dev servers.

So - am I missing something painfully obvious, or has anyone else noticed any issues with Perl on Cygwin?
