Streamlining Site Administration With Drush
In this lesson I show you how you can use the Drush script to streamline Drupal site administration. Drush is a command line interface for your site that allows you to enter short codes to perform a wide variety of site administration tasks including downloading and installing modules, updating modules, updating core, clearing the site cache and much more. Although I don't show you how to install Drush in this lesson you can see a good video on installing Drush at the Level Ten Design blog. The installation of Drush begins at about the five minute mark.
Access to the shell (or the command line) requires a user with appropriate permissions for your web server and a client to allow you to log in and execute commands. If you are on a Windows PC you can utilize the free PuTTY software to gain access to the command line. If you are on a Mac you can use the Terminal application that is included with OS X.
