A collection of Drupal Drush one liners and commands

Some quick one-liners that can come in handy when using drush, Drupal’s command line interface.

Place all websites in Drupal maintenance mode

$ drush @sites vset site_offline 1

Place a specific multi-site website in maintenance mode

$ drush -l site_alias_name vset site_offline 1

Take all sites out of maintenance mode

$ drush @sites vset site_offline 0

Set the cache lifetime for all sites to 1800 seconds

$ drush @sites vset cache_lifetime 600
$ drush @sites vset page_cache_maximum_age 1800

List all sites in a multi-site drupal setup

$ drush @sites status
You are about to execute 'status' non-interactively (--yes forced) on all of the following targets:
  /var/www/html/site#multisite_A
  /var/www/html/site#multisite_B
Continue?  (y/n):
...

Flush all caches (varnish, memcached, …)

$ drush @sites cc all

Disable drupal’s cron

$ drush @sites vset cron_safe_threshold 0
