Drush Commands Chapter 15 ■ Using Drush Executing Drush commands is relatively simple and straightforward. From a terminal window or other tool that allows you to access the command line of your operating system, navigate to the document root directory of your Drupal site. To give Drush a try, from the command prompt type drush status and press Return. The output returned by Drush should look something like the following: Drupal version : 8.0-dev Site URI : http://default Database driver : mysql Database username : d8 Database name : d8 Database : Connected Drupal bootstrap : Successful Drupal user : Anonymous Default theme : bartik Administration : seven theme PHP executable : /usr/bin/php PHP configuration : PHP OS : Darwin Drush version : 7.0-dev Drush configuration : Drush alias files : Drupal root : /Applications/MAMP/htdocs/d8 Site path : sites/default File directory path : sites/default/files Temporary file : /Applications/MAMP/tmp/php directory path Active config path : sites/default/files/config_lFEpXnCuJgRcTN0kwUlVqp7FAr JU7Cj4s2AbZN9Fg6W22BksQHWkPzhJGqU4cfs0Ix2UD7YEqg/active Staging config path : sites/default/files/config_lFEpXnCuJgRcTN0kwUlVqp7FAr JU7Cj4s2AbZN9Fg6W22BksQHWkPzhJGqU4cfs0Ix2UD7YEqg/staging The status command returns a list of helpful information about your current Drupal 8 installation. Another key example is to download a module or theme using the drush pm-download command: drush pm-download calendar This command would download the latest production version of the Calendar module to your site. There is also a shortened version of the command, drush dl calendar. To enable the Calendar module (for example) from the command line, you would execute drush pm-enable calendar or the shortened version, drush en calendar. 171
Chapter 15 ■ Using Drush To disable the Calendar module, use drush pm-disable calendar or the shortened version, drush pm calendar. If a new version or security patch for the calendar module is released and you’re ready to apply the update, run drush pm-update calendar or the shortened version, drush up calendar. As you can see, what may take several clicks through the administrative interface can be done through simple and quick command-line tools. Table 15-1 represents a comprehensive list of common Drush commands. For a more complete description, visit http://drush.org. Table 15-1. Core Drush Commands Command archive-dump archive-restore cache-clear cache-get cache-set core-config core-cron core-execute core-quick-drupal core-requirements core-rsync core-status core-topic drupal-directory help image-flush php-eval php-script queue-list queue-run Description Back up your code, files, and database into a single file.
