What is WordPress CLI?
If you use WordPress and are into WordPress development, you need to know about WP-CLI or WordPress Command Line Interface. It helps in managing WordPress installation using the command line interface. In this detailed article, I will explain WP-CLI, WP-CLI installation, and WP-CLI commands.
WP-CLI (WordPress Command Line Interface) is a command-line tool for managing and interacting with WordPress installations. It allows developers, site administrators, and advanced users to perform various WordPress-related tasks directly from the command line, without the need to use a web browser or access the WordPress admin dashboard.
