Hi monks,

I've a banned-word list stored in a text file. Each word is stored in a new line The file is saved in Windows and uploaded to a Unix server. The code that attempts to check for banned words is as follows: 

sub filter {
  my $data = shift;
  open(FH, "filter") or die $!;
  my @words = <FH>;
  foreach my $word (@words) {
    #chomp $word;
    $word =~ s/\r//;
    $word =~ s/\n//;
    error('bad word found') if ($data =~ /$word/i);
  }
  return $data;
}

In Windows, the chomp line works and I don't have to have the two regex lines to remove the new line. I know it works because when $data contains a banned word, the error sub is triggered.

In the unix server, the same script doesn't work with chomp so I replaced it with '$word =~ s/\r//;' and '$word =~ s/\n//;'. Only then does the banned word check work i.e. when $data contains a banned word, the error is triggered.

Maybe I'm too tired...

Thanks for reading :)

update: That explains why I was getting the behaviour I wasn't expecting. Thanks!
