20 essential WP-CLI commands for managing WordPress sites in 2026

WP-CLI is WordPress's official command-line interface, enabling developers and administrators to perform bulk operations, automate repetitive tasks, and manage sites that are inaccessible via a browser. In 2026, proficiency with WP-CLI has become a core skill for professional WordPress management, particularly for agencies overseeing multiple sites or teams working across staging and production environments. The tool can be installed on Linux servers by downloading the official Phar binary from GitHub and placing it in the system path, while hosts like Kinsta and WP Engine offer it pre-installed via SSH. Advanced configuration is handled through a wp-cli.yml file at the project root, which supports SSH aliases that allow remote commands to be run as if executed locally. Key commands covered include core updates via wp core update, database schema updates with wp core update-db, and bulk plugin updates using wp plugin update --all.
