WP-CLI is the command-line interface for WordPress. You can update plugins, configure multisite installations and much more, without using a web browser.
Using
WP-CLI provides a command-line interface for many actions you might perform in the WordPress admin. For instance, wp plugin install –activate (doc) lets you install and activate a WordPress plugin:
$ wp plugin install user-switching --activate
Installing User Switching (1.0.9)
Downloading installation package from https://downloads.wordpress.org/plugin/user-switching.1.0.9.zip...
Unpacking the package...
Installing the plugin...
Plugin installed successfully.
Activating 'user-switching'...
Plugin 'user-switching' activated.
Success: Installed 1 of 1 plugins.
WP-CLI also includes commands for many things you can’t do in the WordPress admin. For example, wp transient delete –all (doc) lets you delete one or all transients:
$ wp transient delete --all
Success: 34 transients deleted from the database.

Installing
Downloading the Phar file is our recommended installation method for most users. Should you need, see also our documentation on alternative installation methods (Composer, Homebrew, Docker).
Before installing WP-CLI, please make sure your environment meets the minimum requirements:
UNIX-like environment (OS X, Linux, FreeBSD, Cygwin); limited support in Windows environment
PHP 5.6 or later
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 u+x wp-cli.phar
sudo mv wp-cli.phar /usr/local/bin/wp
If WP-CLI was installed successfully, you should see something like this when you run wp –info:
$ wp --info
