Rewrite
Rewrite Flush
wp rewrite flush
Flushes rewrite rules.
Resets WordPress' rewrite rules based on registered post types, etc.
To regenerate a .htaccess file with WP-CLI, you'll need to add the mod_rewrite module to your wp-cli.yml or config.yml. For example:
apache_modules:
  - mod_rewrite
OPTIONS
[--hard] : Perform a hard flush - update .htaccess rules as well as rewrite rules in database. Works only on single site installs.
EXAMPLES
$ wp rewrite flush
Success: Rewrite rules flushed.
