samba - Jan 2004 - dfree and linux quota

Hello Group!

I solved my problem about free disk space for users homes' combined
with quotas on linux box with a small perl script and the %U extension
parsed to my script. But I also have shares on other harddrives and there
are no quota. Now my question:

How can I get the real path of a share parsed to my dfree-script?

Thanks in advance

I've tried any other substitution but without any positive result.
My dfree command entry: dfree command = /scripte/dfree/smb_dfree.pl %U

My perl scirpt:
#!/usr/bin/perl
use Quota;
my ($dev,$uid,$isgrp);
my ($bc,$bs,$bh,$bt,$ic,$is,$ih,$it);
$dev="/dev/md3";
#$uid=`getent passwd $ARGV[0]|cut --delimiter=\: --fields=3-3`;
$uid=`getent passwd sjohlae|cut --delimiter=\: --fields=3-3`;
($bc,$bs,$bh,$bt,$ic,$is,$ih,$it) = Quota::query($dev,$uid,$isgrp);
my $dspace = $bs;
my $dfree = $bs - $bc;
my $bsize = 1024;
print "$dspace $dfree $bsize\n";
