Drush has been part of the Drupal community since Drupal 4.7 and is a custom-built command-line tool. The Drupal Console is a Symfony Console-based application used to interact with Drupal. The Drupal Console project provides a means for configuration management over the command line.
You can learn more about the Drupal Console in Chapter 13, Drupal CLI or at http://www.drupalconsole.com/.
The workflow is the same, except the naming of the command. The configuration export command is config:export, and it is automatically exported to your system's temporary folder until a directory is passed. You can then import the configuration using the config:import command.
