In the world of websites, keeping things fresh is a big deal. If you run a WordPress website, it has a central engine called the "WordPress core" that needs regular updates to run smoothly and stay secure. While there's an automatic update option, some of us want a bit more say in how things are done. That's where WP-CLI (WordPress Command Line Interface) comes in handy. Think of it as your tool for giving your website the exact care it needs.
