Download Different Versions of Drupal with Drush
Warning: This post is over a year old. I don't always update old posts with new information, so some of this information may be out of date.
If you use Drush, it's likely that you've used the
drush pm-download (or
drush dl for short) command to start a new project. This command downloads projects from Drupal.org, but if you don't specify a project or type "drush dl drupal", the command will download the current stable version of Drupal core. Currently, this will be Drupal 7 with that being the current stable version of core at the time of writing this post.
But what if you don't want Drupal 7?
I still maintain a number of Drupal 6 sites and occassionally need to download Drupal 6 core as opposed to Drupal 7. I'm also experimenting with Drupal 8 so I need to download that as well.
By declarding the core version of Drupal, such as "drupal-6", Drush will download that instead.
$ drush dl drupal-6
This downloads the most recent stable version of Drupal 6. If you don't want that, you can add the --select and additionally the --all options to be presented with an entire list to chose from.
$ drush dl drupal-6 --select $ drush dl drupal-6 --select --all
If you want the most recent development version, just type:
$ drush dl drupal-6.x
The same can be done for other core versions of Drupal, from Drupal 5 upwards.
# This will download Drupal 5 $ drush dl drupal-5 # This will download Drupal 8 $ drush dl drupal-8
For a full list of the available options, type "drush help pm-download" into a Terminal window or take a look at the entry on drush.ws.
