* Update the permalink structure.
*
* Sets the post permalink structure to the specified pattern.
*
* To regenerate a .htaccess file with WP-CLI, you'll need to add
* the mod_rewrite module to your [WP-CLI config](http://wp-cli.org/config/).
* For example:
*
* ```
* apache_modules:
* - mod_rewrite
* ```
*
* ## OPTIONS
*
* <permastruct>
* : The new permalink structure to apply.
*
* [--category-base=<base>]
* : Set the base for category permalinks, i.e. '/category/'.
*
* [--tag-base=<base>]
* : Set the base for tag permalinks, i.e. '/tag/'.
*
* [--hard]
* : Perform a hard flush - update `.htaccess` rules as well as rewrite rules in database.
*
* ## EXAMPLES
*
* $ wp rewrite structure '/%year%/%monthnum%/%postname%'
* Success: Rewrite structure set.
