Writing solid code (and in shell scripts that definitely includes quoting your variables) avoids unnecessary bugs like this one. I've just seen too many poorly written shell scripts with hidden (sometimes even security-relevant) bugs to not do things properly. And it looks cleaner ;-) Best regards Alexander Kurtz
