Override symfony2 console commands?

Question

Is it possible to override symfony2 app/console commands? For example, in the FOS UserBundle I\'d like to add a few more fields it asks when it creates a user with its cons

Answer 1

Symfony 4 has removed bundle inheritance, but you can still override commands by decorating them. It's cleaner and doesn't require a bundle. Just add this to services.yaml:

services:
    App\Command\MyCustomCommand:
        decorates: command_you_want_to_override

Note that command_you_want_to_override is a service name. For older, pre-Symfony 3.3 commands it will be something in lowercase with dots and underscores (eg. doctrine_migrations.diff_command), for newer ones it will be a class name. You can find this name by inspecting its bundle's service config or by searching through output of debug:container. On Linux or macOS it would be:

php bin/console debug:container | grep Command
