Overview
WordPress Command Line Interface (or, wp-cli ) is installed on all servers at DreamHost. This feature allows you to run WordPress commands from your Shell terminal. For example you can import a database, create a new user, update themes and plugins all using wp-cli.
This article is a quick overview of this service. View the following articles for information on how to create a Shell user and log into your server to run these commands.
Listing available commands
Log in to your server via SSH. Once logged in, make sure you’re in your WordPress site’s directory. In that directory run the following command to print a list of available options:
[server]$ wp
The following available commands display:

[server]$ wp plugin --help
This prints a list of available subcommands. For example:
SUBCOMMANDS activate Activate a plugin. deactivate Deactivate a plugin. delete Delete plugin files. get Get a plugin. install Install a plugin. is-installed Check if the plugin is installed. list Get a list of plugins. path Get the path to a plugin or to the plugin directory. search Search the wordpress.org plugin repository. status See the status of one or all plugins. toggle Toggle a plugin's activation state. uninstall Uninstall a plugin. update Update one or more plugins.
You can then combine these with the main command to perform an action. Here is how you’d install a plugin named hello-dolly:
[server]$ wp plugin install hello-dolly Installing Hello Dolly (1.6) Downloading install package from https://downloads.wordpress.org/plugin/hello-dolly.1.6.zip... Unpacking the package... Installing the plugin... Plugin installed successfully.
If you now run wp plugin list, all of your plugins appear:
[server]$ wp plugin list +--------------------+----------+--------+---------+ | name | status | update | version | +--------------------+----------+--------+---------+ | akismet | inactive | none | 3.1.1 | | dreamobjects | inactive | none | 3.5.2 | | hello-dolly | inactive | none | 1.6 | | hello | inactive | none | 1.6 | | jetpack | active | none | 3.5.3 | | varnish-http-purge | active | none | 3.7.2 | +--------------------+----------+--------+---------+
