How to know current active installation profile like standard/minimal etc. on existing drupal site? I have installed minimal installation profile. Is there any entry in database where profile name is mentioned, current active profile.

I wanna get the profile name which is get installed in existing site.
If you go to /admin/reports/status, under Drupal if you see something written after Drupal version, that's your installation profile. If there is nothing, that means it is Standard profile.
