Quick Start Edit

Congratulations! You’ve installed WP-CLI for the first time, and are ready to level-up your use of WordPress. This page contains a brief introduction to WP-CLIWP-CLI WP-CLI is the Command Line Interface for WordPress, used to do administrative and development tasks in a programmatic way. The project page is http://wp-cli.org/ https://make.wordpress.org/cli/ with some example usage.

Introduction Introduction

WP-CLI is a command line interface for WordPress. The project’s goal is to offer a complete alternative to the WordPress admin; for any action you might want to perform in the WordPress admin, there should be an equivalent WP-CLI command.

For instance, because you can install a pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party from the WordPress admin, you can also install a plugin with WP-CLI:

$ wp plugin install akismet
Installing Akismet (3.1.8)
Downloading install package from https://downloads.wordpress.org/plugin/akismet.3.1.8.zip...
Unpacking the package...
Installing the plugin...
Plugin installed successfully.

And, because you can also activate plugins from the WordPress admin, you can activate a plugin with WP-CLI:

$ wp plugin activate akismet
Success: Plugin 'akismet' activated.

One key difference between using the WordPress admin and WP-CLI: performing any action takes many fewer clicks. As you become more familiar with the command line, you’ll notice performing a given task with WP-CLI is generally much faster than performing the same task through the WordPress admin. Investing time upfront into learning how to better use WP-CLI pays dividends in the long term.

Common Terms Common Terms

Throughout your usage of WP-CLI, you’ll hear certain terms used over and over again.

For instance, a command is an atomic unit of WP-CLI functionality. wp plugin install is one such command, as is wp plugin activate. Commands represent a name (e.g. ‘plugin install’) and a callback, and are registered with WP_CLI::add_command() (doc).

The synopsis defines which positional and associative arguments a command accepts. Let’s take a look at the synopsis for wp plugin install:

$ wp plugin install
usage: wp plugin install <plugin|zip|url>... [--version=<version>] [--force] [--activate] [--activate-network]

In this example, <plugin|zip|url>... is the accepted positional argument. In fact, wp plugin install accepts the same positional argument (the slug, ZIP, or URLURL A specific web address of a website or web page on the Internet, such as a website’s URL www.wordpress.org of a plugin to install) multiple times. [--version=<version>] is one of the accepted associative arguments. It’s used to denote the version of the plugin to install. Notice, too, the square brackets around the argument definition; square brackets mean the argument is optional.

WP-CLI also has a series of global arguments which work with all commands. For instance, including --debug means your command execution will display all PHPPHP PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. http://php.net/manual/en/intro-whatis.php. errors, and add extra verbosity to the WP-CLI bootstrap process.
