Introduction

If you are a WordPress developer you need to be using WP-CLI. I honestly can't imagine not having WP-CLI in my arsenal. It simplifies a lot of common WordPress tasks, allowing you to perform them right from your terminal. Here is a list of some of the commands I use most frequently.

Download WordPress core files

This is something you'll usually run at the start of a project when you're getting WordPress all setup. It's also helpful when you're setting up an existing WordPress website on a new environment (staging, production, etc.).

bash

You can specify a certain version by adding the --version flag.

bash

Update WordPress core files

This is really handy when performing any kind of maintenance. You can update WordPress to the latest version without having to leave your developer tools.

It can also be super helpful if you ever need to revert WordPress to a previous version for whatever reason. For example, maybe you updated WordPress to the latest version and something in the new update conflicts with a plugin or something in your code. This is a great way to quickly revert to a previous version while you figure out what's going on.

bash

undefined

You can specify a certain version by adding the --version flag.

If you are downgrading versions you will also need to add the --force flag.

Create a new user

Quickly create a new user from the command line. This is really handy when you're working on a site where you may have been given access to the server, but you haven't been given an account yet. Instead of having to contact someone and waiting for them to create you an account for you, you can easily create one from the command line.

Possible user roles include ‘administrator’, ‘editor’, ‘author’, ‘contributor’, ‘subscriber’.

bash

Update a user's password

If you've ever forgotten your password, or maybe you didn't write it down when you created your user, you can easily update your password with this command. In the command below you would replace 123 with the id of the user whose password you are updating.

bash

undefined

Change your active theme

This command allows you to quickly switch to a different theme. Maybe something is messed up on your website and you want to check if the issue is related to your theme or something else, like possibly a plugin. You can quickly switch to a different theme with this command and see if the issue is present on that theme as well. Then you can quickly switch back.

bash

Plugins

Install a plugin

The easiest way to install plugins you find on wordpress.org. Find the plugin you want, copy the name from the end of the url, and download it from the command line.

You can add the --activate flag to activate the plugin once it's installed.

bash

undefined

See a list of all installed plugins

This will show you all the plugins you have installed on your website. It will show you which plugins are active and inactive. It will also tell what version each plugin is on, and whether or not there are any updates available.

bash

undefined

Update plugins

Quickly update plugins from the command line.

You can update a specific plugin by running the following:

bash

undefined

You can update all plugins with available updates by running the following. Be aware that this may not update all plugins. Some premium plugins may still need to be updated manually.

bash

undefined

Generate a wp-config file

This one can be really helpful when you're automating stuff. I use Gitpod as part of my development workflow, and this is really handy to quickly spin up a fresh copy of any WordPress website I work on. This will create a fresh wp-config.php file using the info you provide it.

bash

undefined

Setup a starter database

This is another one that's really useful when automating your workflow. It can also be really helpful when creating a new WordPress build. This allows you to quickly set up the database tables with information you provide.

bash

undefined

Delete transients

The following command will fix the Function WP_Block_Patterns_Registry::register was called incorrectly error you might encounter after syncing your WordPress database.

If you have Woocommerce installed, you may need to remove it prior to running the command and then add it back after running it.

bash
