Hi Monks!
I would like to know if anyone would have a better way of filtering a file name coming from form in a file upload script using Perl.
I use something like this:
sub filter {
    my $str=shift;
    for ($str) {
        return '' unless $_;
        s/\s+//g;
        s/'/\\'/g;
        tr{\*<>;()\"\'?#\/}{}d;
        s/<script//g;
    }
    $str;
}

Is there a better way? What if another character(s) gets in because its not listed in the subroutine?
Thanks
