[Samba] get quota command

[rick at oit.gatech.edu]

I found the answer to my own question in a round about sort of way..
My NFS server is Solaris w/UFS - thus no group quota support.   It
seems when samba queries for user quotas and group quotas, it gets
unhappy when no group quota is returned, so the quotas are thrown
out and the windows boxes see the entire volume's free, used and
capacity.   To fix this I set the two options in my conf file:
   vfs objects = default_quota:quotasettings
   quotasettings: gid = 65534

I found in the source that the hard limit is used instead of the
soft limit if the user is over quota.

And since I didn't easily find any examples of a "get quota command"
I'll share my super-cheesy script which totally ignores the values
passed to it by samba.  It's not pretty, but it works. 

#!/bin/ksh
PATH=/usr/bin:/usr/sbin:/bin
IAM=`id -un`
# find the user's home file system.
DIR=`ypmatch $IAM passwd | awk -F: '{print $6}' | cut -f 2 -d "/"`
#check and see if they're over quota, as it will affect output
OVER=`quota -F rpc -v $IAM | grep $DIR | wc -w`
#OVER=`quota -f rpc -v $IAM | grep $DIR | egrep -i "expired|days"
#if [ $? -ne 0]; then

# over quota
if [ $OVER -gt 7 ]; then
        RET=`quota -v $IAM | grep ${DIR} | awk -F" " '{print "2 "$2"
"$3" "$4" "$7" "$8" "$9}'`
else
# not over quota
        RET=`quota -v $IAM | grep ${DIR} | awk -F" " '{print "2 "$2"
"$3" "$4" "$5" "$6" "$7}'`
fi
# linux "quota" puts a * after the used blocks if the user is over quota
STRIPPED=`echo $RET | sed 's/*/ /g'`
echo $STRIPPED
