I have drupal 7.54 that are placed in /var/www/html which I use as main site. Also I have drupal 8 (for testing) that are placed in /var/www/html/drupal8 where I have drush.
And there is some problem. When I tried to launch command "drush status" it gives me information about drupal 7. And it happens regardless directory of drush.
How to specify version of drupal on which drush must operate?
And I want to notice that I installed drush not via composer but just downloaded and unzipped it.
