I was working on a project that runs on Apache server that has around 25 + subdomains and run from a single codebase with different databases using Drupal CMS. I needed to clear the inbuilt cache of all subdomains without restarting the server.After searching around. I found a solutions on how to solve this, there is a utility tool named as Drush. It is a command line shell scripting specially built for Drupal. If you do not have drush installed, you can download it from here.
