My point is precisely that there's no way of running arbitrary code even when the regex isn't being checked or cleaned. Of course, the user running this will often be root so this is only an issue if the script is somehow made setuid. I only pointed it out to avoid the typical subthread about "Your usage of /$regex/ is insecure!".
