Note that this script is based of the Greyhole original one and uses ''/etc/samba/smb.conf'' as the source of your shares and does not load the shares from the database like the old HDA version of the script did. If that behaviour is desired that can be easily added by replacing the lines
<pre style="white-space: pre-wrap; word-break: keep-all;">testparm -s /etc/samba/smb.conf 2>/dev/null | grep "^\[" | grep -v "\[global\]" | grep -v "\[homes\]" | awk -F'[' '{print $2}' | awk -F']' '{print $1}' | xargs -d "\n" mkdir -p</pre>
