# change the filter and grep to anything you want to search for. 
# This example shows searching for the name of machines beginning with "dev"
# You can sort by driver or swarm instance, just change the awk column as well
ALLHOSTS=$(docker-machine ls --filter name=dev* | grep dev* | awk '{print $1}')

for host in $ALLHOSTS
do
	echo "$host: Installing REX-Ray"
	docker-machine ssh $host "curl -sSL https://dl.bintray.com/emccode/rexray/install | sh -"
	echo "$host: Setting Permissions for REX-Ray Config File"
	docker-machine ssh $host "sudo chmod 777 /etc/rexray"
	echo "$host: SCPing REX-Ray Config File from $REXCONFIG"
	docker-machine scp $REXCONFIG $host:/etc/rexray/config.yml
	echo "$host: Starting REX-Ray Service"
	docker-machine ssh $host "sudo rexray start"
done

Would probably be best to set permissions to 700 on that directory after transferring.
