If you are a system administrator and responsible for managing hundreds or thousands of WordPress websites then it is a very time-consuming process. You will need to log in to each WordPress control panel, install or update plugins and themes. This is the place where the WP-CLI comes into the picture. The

WP-CLI is a powerful command-line tool specifically designed to manage WordPress from the command line. You can manage multiple WordPress sites without log into the WordPress admin panel. With WP-CLI, you can perform several operations including, installing and updating plugins, themes, creating content, working with databases, and more.

In this post, I will show how to install and use WP-CLI to manage WordPress sites.

Prerequisites

  • A server running Ubuntu 20.04 with WordPress installed.
  • A root password is configured on the server.

Getting Started

First, you will need to update the APT package cache to your system. You can update it with the following command:

apt-get update -y

Once your system is updated, you can proceed to the next step.

Install WP-CLI

First, download the WP-CLI binary with the following command:

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

Once downloaded, set proper permission to the downloaded file:

chmod  x wp-cli.phar

Next, copy the downloaded binary to the system path with the following command:

cp wp-cli.phar /usr/bin/wp

Now, verify the WP-CLI version with the following command:

wp cli version --allow-root

You should see the following output:

WP-CLI 2.5.0

Manage Plugins with WP-CLI

In this section, we will learn how to search, install, update, and delete plugins on a WordPress site from the command line.
