Is there a way to clear cache on all sites in platform by using platform alias? For example, drush @platform_name cc all
? (its multisite setup via aegir).
The problem I am facing with is, when I run that command or the one with @sites, I get a message
Could not find a Drupal settings.php file at sites/default/settings.php.
So, I then copied default.settings.php as settings.php (which is by default fully commented out) in sites/default, and then it says
Drush was not able to start (bootstrap) the Drupal database.
Which is obvious, as default doesn't have database (Aegir creates all sites in platform as separately and never touches default).
I also tried to delete default folder but Drush is telling me it needs to have settings.php there (even after I cleared drush cache). Drush in question is 8.1.0.
