keystone_user_add.sh

#!/bin/bash
source ~/openrc

echo Argv: $#

if [[ $# -lt 3 ]]
  then
	echo -e "Usage:\n${0} user password e-mail@address [tenant=openstack]"
else
	user_id=`keystone user-list | grep ${1} | awk -F' ' '{print $2}'`
	if [ ! -z ${user_id} ]
	then
		echo "error! username already exists"
		exit 1
	fi
	if [[ $# -eq 3 ]] 
	then
		tenant_id=`keystone tenant-list | grep openstack | awk -F' ' '{print $2}'`
		keystone user-create --name=${1} --pass=${2} --email=${3} --tenant-id=${tenant_id}
