This is a fish shell lang. I put this stuff to ~/.config/fish/config.fish to have boot2docker automatically started

boot2docker-auto-startup.fish

if [ (boot2docker status) != "running" ]

	# start boot2docker
	boot2docker start

	# put VM ip into /etc/hosts
	sudo sed -i '' '/docker/ d' /etc/hosts
	set boot2docker_vm_ip (boot2docker ip) 
	echo "$boot2docker_vm_ip docker" | sudo tee -a /etc/hosts 
end;

# set all env variables
set shinit (boot2docker shellinit)
for i in (seq (count $shinit))
        eval $shinit[$i]
end
