Do you use the WordPress dashboard to update plugins and themes? How do you back up your database? If you have not used it yet, WP-CLI is an efficient way to manage your WordPress installation using a command line interface, meaning you type text commands like these two:
wp core update wp plugin update-all
You type these lines into a Secure Shell (SSH) window that is connected to your website server. If you are new to using command line interfaces, this is a great place to start learning. Beginners will feel like masters of the Matrix in no time.
