The upgrade command upgrade all the sites (and their plugin) installed with VV.
There is a problem in this pr, the loop works but executing the vagrant command don't let the loop to wait to finish the execution (so only one sites is updated), at the same time I want that all the output of the command is not printed (print stuff about wrong bash locales, status of the update of wp with the errors about using in console etc.)
