Vagrant plugin update *

From time to time, you should update your Vagrant plugins.

This one-liner makes it very easy to ensure that the latest versions are installed.

for plugin in `vagrant plugin list | awk '{print $1}'`; do vagrant plugin update $plugin; done

Just copy&paste it, hit return and grab a cup of coffee.

Among others, I highly recommend the following plugins:

vagrant-cachier

vagrant-vbguest
