Removing and Deleting old git releases
There comes a time when you don’t need all your releases of your gitified app on your server. It just takes up way too much space. In this event, you can issue the following command for your capistrano deploy
This, of course, assumes you’ve already setup Capistrano to work with Git for your project.
cap deploy:cleanup
It might take a while to delete all those though so just be patient. I had 150 releases to delete and it took about 7 minutes.
