Drupal Shell (Drush) is a command-line shell that can also be used as a scripting interface for Drupal websites. Drush is more flexible, more precise, faster, and uses less system resources than does the administration functions built into Drupal's GUI web-interface. Drush provides many useful utilities for site administrators and developers. Drush was created by Arto Bendiken in 2006 and evolved into a fully maintained Drupal project. Documentation for drush can be found at drush.org and drupal.org/project/drush.
Drush typically resides on the same web hosting environment as it manages. Drush was designed for Linux, however a lesser version for Windows and Mac are available. Access to the command line shell (e.g. SSH) in the location of the Drupal site installation is required for Drush. The recommended host environment for Drush is:
- Apache 2+
- PHP 5.3+
A Drush Windows installer is available at drush.org. It supports the shells minsw, msysgit, PowerShell and the command prompt. Download the Drush Windows installer and execute the program.
Verify Drush was installed by clicking on the Drush icon and entering the command "drush". The Drush help screen should be displayed.
