Typing vagrant from the command line will display a list of all available commands.
Be sure that you are in the same directory as the Vagrantfile when running these commands!
vagrant up -- starts vagrant environment (also provisions only on the FIRST vagrant up)
vagrant status -- outputs status of the vagrant machine
vagrant halt -- stops the vagrant machine
vagrant reload -- restarts vagrant machine, loads new Vagrantfile configuration
vagrant provision -- forces reprovisioning of the vagrant machine
