Drush or drupal shell is a command-line utility to help the site building and maintenance workflows.
Available Drush Commands:
For a list of available commands type drush help.
For a printable version use drush help --html
Extensions
Other modules provide new drush commands! These become available automatically and are listed when you run drush help.
Tips
Drush autodetects the appropriate site from directory context, and read its configs from there, so if your command shell is in {drupaldir}/sites/all or anywhere under {drupaldir} then drush commands will apply to your default install. If you move your shell session into {drupaldir}/sites/mysite, then drush commands will be run in the context of the mysite multisite instance. You can always run drush status to check the currently active context.
When updating with Drush, it is not necessary to put the site in maintenance mode.
Example Commands
drush dl cck zen- Download current recommended versions of CCK module and Zen theme.
drush en content- Enable the content (cck) module.
drush vset theme_default theme_name- make theme_name theme default theme
drush --uri=http://example.com status- Show status command for the example.com multi-site.
