Can I flush W3TC’s cache in a capistrano deploy? [closed]

As @andreascreten, wp-cli will do the job for you.

wp-cli includes commands for W3TC (located in the src/php/wp-cli/commands/community/total-cache.php file), so you can flush the cache by running:

$ wp total-cache flush <type>

Where <type> is one of ‘db’, ‘minify’, ‘object’, ‘page’ or ‘post’.

(Note: If you use ‘post’, you’ll need to pass in --post_id= or --permalink= as well)
