Developers and users of WordPress are all too familiar with the
/wp-admin administration panel and how it works.
This guide is for users and admin alike. I’ve heard them many times complaining (system admins in particular) about WordPress, and how due to the plethora of configuration options in the WordPress admin panel it can often become fiddly and confusing finding where to click or remembering where a certain feature is residing. As it is all down to the plugin creators, there is no centralised way to interact with WordPress as an actual direct command interface.
Well, those days are truly over because WordPress has a command-line tool, and it’s a serious timesaver!
Get the Tool
WP-CLI with the following at the terminal prompt:
$ curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
Check it worked with:
php wp-cli.phar --info
Now to set this as just a
wp command available anywhere, run the following:
chmod +x wp-cli.phar sudo mv wp-cli.phar /usr/local/bin/wp
This will require your root password for completion of the
For the official guide, go to the WP-CLI website to get more detailed instructions and information about the
WP-CLI project (such as MAMP configuration issues and other useful support topics)
To use the
WP-CLI tool, just
cd to your WordPress installation directory and run
Working with the
wp tool is very self-explanatory. You can perform any of the functions from the browser-based tool now on the command line. Blog creation, code execution, plugin support—it’s all here.
To learn more about the functionality of
wp, just run
wp help <command>, e.g.:
$ wp help cli DESCRIPTION Get information about WP-CLI itself. SYNOPSIS wp cli
SUBCOMMANDS check-update Check for update via Github API.

From here, you can perform an update of WordPress with
update or just check if one is needed with
To back up your WordPress with the CLI, just run:
$ wp db export
This will give you an uncompressed backup and a .SQL file which you can then create a tarball from as so:
$ tar -vczf yourbackupfilename.gz .
Restoring From a Backup
Set the webroot of your server to the directory created by the
wp db export command and import the
mysql as so:
$ mysql -u<username> -p<password> wordpress < backup.sql
Installing a Plugin
To install a plugin, you can simply run:
$ wp plugin install <plugin name>
You can see what plugins are installed with
wp plugin list:
$ wp plugin list +-------------+--------+-----------+---------+ | name | status | update | version | +-------------+--------+-----------+---------+ | jetpack | active | none | 3.7.2 | | woocommerce | active | available | 2.4.7 | +-------------+--------+-----------+---------+
You can turn these plugins on and off with the
deactivate arguments as so:
$ wp plugin activate jetpack Success: Plugin 'jetpack' activated.
To make your
wp work with a multisite WordPress installation, you just need to pass the
--url argument as so:
$ wp theme status --url=localhost/wp/test # For a subdomain just specify the url $ wp theme status --url=subdomain.my-wordpress-site.com
If you want
wp to remember your
--url configuration, you can specify it in a
wp-cli.yml, which must be located inside your WordPress root.
Add the following to your
You will now be able to omit the
--url argument from your
wp commands, e.g.:
$ wp theme status
This will read the configuration from the
wp-cli.yml and pass the
--url test.example.com for you.
To check for updates, back up your WordPress, add or remove plugins, or change themes, you can do it all now without leaving the command prompt. This makes wp-cli a very powerful tool indeed.
