Hi Karl, I tried your script and I couldn't get it to output anything to 
a temp file until I altered it to this:

#!/bin/bash
# /usr/local/bin/query_quota.sh

PATH=/usr/bin:/usr/sbin:/bin

IAM=`id -un`

# find the user's home file system.
DIR="home"

#check and see if they're over quota, as it will affect output
# user with reached quota has 9 fields in row, 'ok' user only 8
OVER=$(/usr/sbin/repquota /$DIR | grep -w $IAM | wc -w)

# over quota
if [ "$OVER" = "9" ]; then
     RET=$(/usr/sbin/repquota /$DIR | grep -w $IAM  | awk -F" " '{print 
"2 "$3" "$4" "$5" "$7" "$8" "$9}')
else
     # not over quota
     RET=$(/usr/sbin/repquota /$DIR | grep -w $IAM  | awk -F" " '{print 
"2 "$3" "$4" "$5" "$6" "$7" "$8}')
fi

echo "$RET"
echo "$RET" > /tmp/results.txt

exit 0

I also ran these two commands:

chmod +r /home/aquota.group
chmod +r /home/aquota.user

With the above alterations, I get this in /tmp/results.txt:

2 157536380 0 0 134072 0 0

Which I think is what you require ;-)
