OLD_MACHINE_NAME=${1:-default};

STORE_PATH=$(docker-machine inspect ${OLD_MACHINE_NAME} | sed -n 's/^ *"StorePath": "\(.*\)",/\1/p')

# 1. rename the directory of your docker-machine from docker machine store
mv "$STORE_PATH/machines/$OLD_MACHINE_NAME" "$STORE_PATH/machines/$NEW_MACHINE_NAME";

# 2. update config.json with the new name and new path (always backup your configs)
sed -i.bak "s/${OLD_MACHINE_NAME}/${NEW_MACHINE_NAME}/g" ${STORE_PATH}/machines/${NEW_MACHINE_NAME}/config.json

# 3. rename machine in the virtual machine provider
vboxmanage modifyvm "$OLD_MACHINE_NAME" --name "$NEW_MACHINE_NAME"

@eurythmia nice!
