WP-CLI
Resources

We’ve seen your bumper sticker: real coders do it from the command line, eh? If you’d like to be able to manage your WordPress installs without opening a web browser, WP-CLI is for you. Did we mention it works with Multisite, too?
Created by Andreas Creten, and maintained by Cristi Burcă, WP-CLI is a set of command-line tools for managing WordPress installations. You can install and update plugins, set up multisite installs, manage posts, users, and themes — and we’re only scratching the surface. You can do much much more.
