One of the most useful WordPress tricks is to use the WP-CLI interface to manage your WordPress site. The WP-CLI is a set of command-line tools for managing WordPress installations. You can use it to update your WordPress site, install and update plugins, manage users, and more.

To use the WP-CLI, you need to install it on your server. You can find instructions on how to do this at https://make.wordpress.org/cli/handbook/installing/.

Once you have the WP-CLI installed, you can use it to manage your WordPress site from the command line. For example, you can use the wp plugin install command to install a plugin:

wp plugin install bbpress

You can also use the wp plugin update command to update a plugin:

wp plugin update bbpress

There are many other commands that you can use to manage your WordPress site with the WP-CLI. To learn more about the WP-CLI, check out the documentation at https://make.wordpress.org/cli/handbook/.
