Help:
  The list command lists all commands:

    php bin/console list

  You can also display the commands for a specific namespace:

    php bin/console list test

  You can also output the information in other formats by using the --format option:

    php bin/console list --format=xml

  It's also possible to get raw list of commands (useful for embedding command runner):

    php bin/console list --raw
