Drush has integration with SVN which makes it easy to update a module and automatically commit the new version of the code to SVN.
In this example we use Drush to update a fictional module named "modulename" and then commit the changes to SVN along with a commit message for the SVN log:

drush up modulename --svnsync --svncommit --svnmessage="svn commit message."

To update all outdated Drupal core and contrib modules modules:

If you use Drush you will be delighted to learn that Subs integrates with Drush and exposes a number of useful commands:

• subs-cron
• subs-load
• subs-delete
• subs-status
• subs-pending
• subs-active
• subs-grace
• subs-expired
• subs-cancel

subs-cron

Executes subs cron script. Use this to execute the subs cron script independently from Drupal's cron:

drush subs-cron

Since Subs uses Drupal 7's Job Queue API, this can be useful, for example, if you want to make sure that all subscriptions get processed quickly.

subs-load

Load and view a subscription. This can be useful to quickly load and inspect a subscription. It accepts two parameters: the subscription's id and a boolean indicating if you want to load the full entity information (defaults to false):

drush subs-load 15

To download a specific version of a project, specify the project name, followed by a dash, then the version name. The -y argument answers "yes" to any and all prompts.

drush dl og-1.3 # shortcut for pm-download
drush -y en og # shortcut for pm-enable

alternatively, you can have a specific Drupal version's latest release

drush dl og-7.x

or you can specify a specific version:

To disable and re-enable a project:

drush -y dis PROJECTNAME; drush -y en PROJECTNAME

If you have Devel installed, there is an additional command available; devel-reinstall which will disable, uninstall, and install a list of projects.

drush -y devel-reinstall PROJECTNAME
