WP-CLI

WP-CLI is a set of command-line tools for managing WordPress websites. With just a few simple commands, you can manage WordPress from the command line without the need to login to the Admin Dashboard and navigate the pages. You can install, update and delete plugins and themes, perform backups, configure standard and multisite installs and much more — all without ever using a web browser.
