Greetings,
I have an externally supplied attachment filename which I need to
untaint but still use. I'd like to replace any unsafe characters with
underscores. This is what I've tried:
$attach_name =~ s/[^\w\s\-\.]/_/;
$safe_attach_name = $1;
However, this isn't populating $safe_attach_name with anything. What am
I doing wrong?
Thanks in advance,
Damon
