f you’ve ever shopped around for WordPress hosting, you’ve probably seen this weird little acronym that shows up on many hosts’ features lists:


Are you familiar? Most managed WordPress hosts offer it nowadays.

Impressively, it manages to pack two different acronyms into a name that’s the perfect storm for confusing beginners. So what does this acronym mean? And why should you care about it?

If you’re a WordPress developer, you’re probably already familiar with WP-CLI, or at least the concept of command line interfaces. Which is why this post isn’t really for you.

Instead, this post is focused on giving regular WordPress users a basic understanding of WP-CLI. I’m not going to argue that every WordPress user should start using WP-CLI – this post is just a fun way for regular ‘ole WordPress users to learn more about the WordPress ecosystem.


Ok, I already told you that this is two acronyms jammed into one. The WP stands for, unsurprisingly, “WordPress”. And the CLI stands for “command line interface.

Put it all together and you get…WordPress command line interface.

Ok, great. It’s a command line interface for WordPress…what the heck is a command line interface?

Command line interfaces are what you normally see super smart “hackers” typing away at in popular TV shows. That is, they look like this:


And if you used a computer before the, oh…1970s, that’s the only way you could interact with it.

With command line interface, you basically “speak” to the computer in a series of text commands, rather than using your mouse to click buttons on your screen (or some other type of input).

For casual users, command line interfaces aren’t exactly user friendly (to say the least). But if you know your way around the commands, it can actually save you time. Which was why WP-CLI was born.


Basically, WP-CLI lets you manage most aspects of your WordPress site without needing to log into your dashboard. If you’re only managing a single WordPress site, this might not be a huge draw. But if you need to work with multiple sites, you can start to see the appeal of that.

Or, it can also help out if you need to do other things for testing like programmatically generating a few hundred posts. And lots more!

Here’s some of what you can do with WP-CLI:

  • Install a plugin or theme
  • Delete a plugin or theme
  • Update a plugin or theme
  • Run a backup
  • Delete a post (or lots of posts)
  • Clear your transients cache
  • Create an export file
  • Back up your database
  • Lots, lots more

You can even write a post directly from WP-CLI! Though, to be fair, it’s probably a bit easier to use the WordPress Editor for that.


Unfortunately, you can’t just hop into cPanel and start playing around with WP-CLI. You’ll need something called SSH access, or Secure Shell access.

Depending on your host, you:

  • May already have SSH access
  • Might need to enable SSH access through cPanel
  • Might need to ask your host to enable it for you
  • Won’t be able to get SSH access (for some shared hosts)

If you want to really go ahead and use WP-CLI – it’s probably best to ask your host for help getting set up.

Once you’ve got that, you’re ready to start firing off some WP-CLI commands (assuming your host supports WP-CLI – otherwise you might need to install it first). I’ll show you these using PowerShell for dramatic effect, though I’m not actually connected to anything right now.


WP-CLI lets you install any theme at the WordPress.org directory with a command that’s shorter than this sentence is.

For example, if you wanted to install the Twenty Seventeen WordPress theme with WP-CLI, all you’d need to do is use the command:


wp theme install twentyseventeen

Want Twenty Sixteen instead? You guessed it:

wp theme install twentysixteen



It’s pretty much the same deal for WordPress plugins. If you wanted to install the Akismet plugin (or any other plugin from WordPress.org), you’d just use this short command:

wp plugin install akismet

Then, to activate your plugin, you could just type:


wp plugin activate akismet

And if you changed your mind about comment spam because you missed all of those kind people complimenting your blog posts with spun comments, then you could go ahead and deactivate Akismet by using:

wp plugin deactivate akismet

Simple enough, right? No weird computer language – the commands are pretty much written in plain English.

In conclusion

If you master it, WP-CLI is a powerful tool to help you manage all of your WordPress sites. Nowadays, many WordPress focused hosts offer WP-CLI by default, which is making it more accessible (you can even find a full list of all those hosts here).

But if you’re a beginner, you’re still better off leaving WP-CLI to the professionals. But now, you’ll at least know what you’re paying for the next time you see WP-CLI on a WordPress host’s feature list!

Now over to you – if you do use WP-CLI, I’d love to hear more about how it helps streamline your WordPress experience.
