On a local machine
drush features-revert-all
will convert all features to codebase definition. On a local machine ...
drush -y
will auto-yes any command. On a local machine
terminus -y command
will auto-yes as well.
But when combined, even
terminus -y drush -y yoursite.dev -y features-revert-all -y
... will still ask for a key-press.
How can it be forced to run non-interactively?
You need to add a -- separator to your command. The options for Terminus come before this marker, and the options for Drush come after.
In other words:
terminus -y drush site.dev -- features-revert-all -y
Explanation:
In programs that support it, -- means "all of the options that come after should be treated as arguements". The command terminus drush passes all of its arguments through to Drush.
