Getting Services from the Service Container
-------------------------------------------

By using :class:`Symfony\\Bundle\\FrameworkBundle\\Command\\ContainerAwareCommand`
as the base class for the command (instead of the more basic
:class:`Symfony\\Component\\Console\\Command\\Command`), you have access to the
service container. In other words, you have access to any configured service.
For example, you could easily extend the task to be translatable::

protected function execute(InputInterface $input, OutputInterface $output)
{
$name = $input->getArgument('name');
$translator = $this->getContainer()->get('translator');
if ($name) {
$output->writeln($translator->trans('Hello %name%!', array('%name%' => $name)));
} else {
$output->writeln($translator->trans('Hello!'));
}
}
