Add this to your bash script to avoid docker-machine env dev blocking your bash if dev isn't running

.bash_profile

docker_running=$(docker-machine ls | grep dev)
if [[ "$docker_running" == *"Stopped"* ]]
then
	echo "fyi - docker not running"
elif [[ "$docker_running" == *"Running"* ]]
then
	eval "$(docker-machine env dev)"
fi

I was seeing a situation where my bash console wasn't loading because docker-machine env dev wasn't returning because dev wasn't running, so I did a conditional check on the state of whether dev docker-machine was running, before doing the eval.

The fyi statement isn't vital, I just found it informative for me.

now I use something like this

docker_running=$(docker-machine ls | grep dev)
if [[ "$docker_running" == *"Stopped"* ]]
then
    docker-machine start dev
    eval "$(docker-machine env dev)"
    env | grep "DOCKER_HOST"
elif [[ "$docker_running" == *"Running"* ]]
then
    eval "$(docker-machine env dev)"
fi
