WP-CLI is a command line tool for interacting with and managing WordPress sites. WP-CLI is very similar in functionality to what drush provides Drupal.

The current stable release is version 2.0.1. For announcements, follow @wpcli on Twitter or sign up for email updates. Check out the roadmap for an overview of what’s planned for upcoming releases.

In this tutorial we’ll learn how to install wp-cli on a server and some basics. With WP-CLI you can speed up common WordPress maintenance, automate tasks etc.

Installing wp-cli for All Users

Installing a tool like wp-cli on a server globally means that any user will be able to use the application. With WordPress being one of the most common CMS’ it’s helpful to have wp-cli installed for all users.

Pre-flight Check:
Before installing WP-CLI, please make sure your environment meets the minimum requirements:
1. UNIX-like environment (OS X, Linux, FreeBSD, Cygwin); limited support in Windows environment.
2. PHP 5.4, or higher, will be required for wp-cli to function.
3. WordPress 3.7 or later. Versions older than the latest WordPress release may have degraded functionality.

Once you’ve verified requirements, download the wp-cli.phar  file using wget or curl:

/curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar

Next, check the Phar file to verify that it’s working:

php wp-cli.phar –info

To use WP-CLI from the command line by typing wp, make the file executable and move it to somewhere in your PATH. For example:

/chmod +x wp-cli.phar
/sudo mv wp-cli.phar /usr/local/bin/wp

If WP-CLI was installed successfully, you should see something like below:

[root@server ~]# wp –info
OS: Linux server.linux.com 3.10.0-514.10.2.el7.centos.plus.x86_64 #1 SMP Fri Mar 3 02:04:03 UTC 2017 x86_64

WP-CLI root dir: phar://wp-cli.phar/vendor/wp-cli/wp-cli
WP-CLI vendor dir: phar://wp-cli.phar/vendor
WP_CLI phar path: /root
WP-CLI packages dir:
WP-CLI global config:
WP-CLI project config:
WP-CLI version: 2.0.1

Updating wp-cli

You can update WP-CLI with wp cli update, or by repeating the installation steps.

Verify & Test wp-cli as a Site User

Now that wp-cli is installed globally you will want to test the tool from a user hosting a WordPress site. To do this you will log in as root via SSH then switch to a normal user (SSH access should be enabled for the user).

$ su – wordpress

By executing this command you will then be logged in as the ‘wordpress’ user. Do take note that you’ll enter the actual username where it says ‘wordpress’.

First, let’s get the current version of WP-CLI we’re running.

$ wp –version

Manage WordPress Plugins & Themes

WP-CLI can be used to manage WordPress plugins from the command line. This is useful for scripting or automating the management of your plugins. To get information about all the WP-CLI commands related to plugins, run the following

$ wp help plugin

NAME

wp plugin

DESCRIPTION

Manages plugins, including installs, activations, and updates.

If you wish to only upgrade a single plugin for some reason, you can do that with the command:

WP-CLI can be used to manage themes in a similar way it can be used to manage plugins – it can install, enable, update, and much more, all from the command line. To get information about all the WP-CLI commands related to themes, run the following:

Upgrade WordPress Core from the Command Line with WP-CLI

Get started by checking the version of WordPress you’re running:
$ wp core version

[wordpress@server public_html]$ wp core version 4.9.7

The WordPress community releases new versions many times a year, minor versions to fix bugs and vulnerabilities, and major versions when new features are added. Chances are, you need to upgrade the core WordPress files to enjoy performance enhancements, security fixes, and new features. The classic way is using the WordPress admin dashboard which requires you to start your browser and click around your site a couple of times. WP-CLI simplifies this task immensely:

$ wp core update

This will check for a newer version of WordPress, and install it if there is one.

[wordpress@server public_html]$ wp core update
Updating to version 4.9.8 (en_US)…
Downloading update from https://downloads.wordpress.org/release/wordpress-4.9.8-no-content.zip…
Unpacking the update…
Success: WordPress updated successfully.

If you need to downgrade WordPress for some reason, WP-CLI can do this as well. The following command will downgrade WordPress core to a version you specify:

$ wp core update –version=VERSION_NUMBER –force

The “–force” flag is required, as it is not recommended that you downgrade WordPress.

Manage WordPress Users

List Existing Users

You can enter the below command to see the list of all your WordPress users:

$ wp user list

The output will look similar to the following:

[wordpress@server public_html]$ wp user list
+—-+————+————–+—————+———————+—————+
| ID | user_login | display_name | user_email | user_registered | roles |
+—-+————+————–+—————+———————+—————+
| 1 | admin | admin | admin@wordpresstest.com | 2018-07-16 10:14:15 | administrator |
+—-+————+————–+—————+———————+—————+

This summarizes the information about your users: their usernames to log in to your site’s WordPress Dashboard, the names displayed on their posts, the dates they registered as users, and their roles.

Create a New User

To create a new administrator user, enter the below command, replacing “NEWUSERNAME” and “EMAILADDRESS” with your user’s information:

$ wp user create NEWUSERNAME EMAILADDRESS –role=administrator

[wordpress@server public_html]$ wp user create newadmnusr
adm@wordpresstest.com –role=administrator
Success: Created user 2.
Password: 4boBRcZscub9lMU4$HfL^yvS

You can set the password with the –user_pass command,replacing “MySecurePassword” with your password:
$ wp user create NEWUSERNAME EMAILADDRESS –role=administrator –user_pass=MySecurePassword

Change a User’s Password

To change a user password, enter the below command :
$ wp user update USERNAME –user_pass=MyNewSecurePassword

 

[wordpress@server public_html]$ wp user update newadmnusr –user_pass=’87gt[fdsd’
Success: Updated user 2.

Remove a User
If you wish to remove a user that does not have any posts you want to preserve, you can do so with this command, replacing “USERNAME” with the user:
$ wp user delete USERNAME
You’ll receive a prompt that the system will delete any posts for this user; press y if you wish to proceed.
If the user has posts you would like to save, you can select another user to assign them to by entering this command and substituting the appropriate usernames for the fields shown in ALL CAPS:
$ wp user delete USERNAME –reassign=ANOTHERUSER
