In a post to his site Stefan Koopmanschap takes a look at the technical term "command" and tries to clear up some of the confusion around its use and how it differs from the idea of a "controller".

A couple of weeks ago while walking towards lunch with Jelrik we were having a bit of a discussion about the use of the term Command. Not long before that, Jelrik had asked a question about naming of Commands in our Slack channel, which led to some confusion.

He starts off by defining what a command is and why it's called a "command" instead of a controller (hint: it "just works" with the Symfony Console). He then gives an example of a command in a Symfony bundle structure and how a CLI "controller" can extend the Command and automatically be integrated into the command structure.
