General assumptions ๏ Who will get the most out of this presentation: ๏ You are reasonably comfortable using command-line utilities. ๏ You know the general concepts of Drupal. ๏ See what Drush can do and how to use it. 3

What is Drush? ๏ Drupal shell ๏ Not a module ๏ Collection of scripts that allow you to perform Drupal tasks from the command line on your web server. 4

So why should I care? ๏ Do you spend a lot of time at a command prompt? ๏ Accomplish admin tasks quicker than via the web interface. ๏ Scriptability of common tasks. ๏ Keeping up to date. 5

All that, and smart, too ๏ Drush knows what site you’re working on. ๏ Drush knows what version of Drupal you are using. 6

Requirements ๏ To be run alongside your Drupal installations (i.e. on a server). ๏ Requires command-line access to PHP 5.2. 7

Getting Drush ๏ http://drupal.org/project/drush ๏ Current release is 3.3. ๏ Download and extract on your server. 8

Installing Drush ๏ See README.txt ๏ Make the Drush script executable. ๏ Create a symlink in /usr/local/bin or create an alias. 9

Configuration ๏ Global and site specific drushrc.php files ๏ Configures path locations, site aliases, checkout handling, database dump options, command-specific options, and variable overrides. ๏ example.drushrc.php is included. 10

Using Drush ๏ $ drush [options] <command> 11

Did I say all versions? ๏ Not all commands are available to all Drupal versions. ๏ site-install requires Drupal 7, several other commands require at least Drupal 6. 12

Package management ๏ pm-disable (dis) ๏ pm-download (dl) ๏ pm-enable (en) ๏ pm-info ๏ pm-list (sm) ๏ pm-refresh (rf) ๏ pm-releases ๏ pm-uninstall ๏ pm-update (up) ๏ pm-updatecode 16

A Drush makefile ๏ From www.openatrium.com/node/35 core="6.x" projects[] = "drupal" projects[openatrium][type] = "profile" projects[openatrium][download][type] = "cvs" projects[openatrium][download][module] = "contributions/profiles/openatrium" projects[openatrium][download][revision] = "DRUPAL-6--1-0-BETA4" 24
