I’m going to explain how to create feature in drupal using drush commands. It is easy and recommended way to update codebase for configuration changes.
Here I’ve made example how to create , update or revert feature either from command line
We usually create new configuration, add fields through Drupal Admin UI,
For example: If you have page content type and you’ll need to add another field for meta description. You can easily go into Admin UI and add new field.
After adding through UI , we can include it in our code base by using drush commands and deploy to live site which will then automatically update without going and change into UI.
