WP CLI is a command line tool to interact with your WordPress installation. Its a way to configure and query WordPress websites without ever having to go to the admin interface.

I find to use it myself very often especially to add, remove and activating plugins but also to generate new users or just to run some simple queries to find out more about the installation. If you haven’t used at all visit wp-cli.org to get to know more about it. In this post however I would like to collect some of the most used commands. Here we go:

Common WP CLI commands

I will give you a few example commands, in some cases they are specific to your config and installation. In these cases I wrote these parameter in all CAPITAL letters. Replace all caps words with your own installs configuration. parameters. For instance replace PLUGINNAME with wordpress-seo if you would like to install the Yoast SEO plugin. Ok, here we go!

1. Downloading WordPress using WP CLI commands

Download an instance of WordPress using WP-CLI. Useful when you are trying to set up a new local instance of an exiting website on a server. If you already have a local DB and files and all you need to get is the WP core files.

wp core download

// To skip default themes and hello plugin etc.
wp core download --skip-content

// To override any existing files in directory
wp core download --force

2. Installing WordPress

Running the default installation process to create a DB user and password etc.

wp core install --url=EXAMPLE.COM --title=EXAMPLE --admin_user=USERNAME --admin_password=STRONGPASSWORD [email protected]

# Install WordPress without disclosing admin_password to bash history

wp core install --url=example.com --title=Example --admin_user=supervisor [email protected] --prompt=admin_password < admin_password.txt

2.1 Get Version ow your WP install

wp core version

2.2 Setting the Admin Email

WP email address where systems emails get sent to, through the user interface you can change this under Settings > General. But this may need to send an email for you to confirm etc.

You can do it with wp cli as well:

wp option update admin_email [email protected]

3. Update WP core using WP CLI

wp core update

# update to a specific version
wp core update --version=4.5.2 --force

# update DB only, for pending DB updates
wp core update-db

# check if update available
wp core check-update

# Re-generate all thumbnails that have IDs between 1000 and 2000.
$ seq 1000 2000 | xargs wp media regenerate

7. Creating or scaffolding new post types and Taxonomies

7.2 Scaffolding new taxonomies
