Based on rick's suggestion (may 29, 08),

http://code.google.com/p/gnizr/wiki/SetupGnizrDatabase

I modified his script and added the following:

rows=`mysql -u $USER -p${PASS} -e "show tables" $DB |wc -l`
if [ $rows -gt 0 ]
then echo "Looks like the gnizr has already been installed."
echo "Enter YES to continue (ALL EXISTING DATA WILL BE LOST!): "
read input
if [ "$input" != "YES" ]
then echo "Quit! No changes are made."
exit 1
