\part{Removing User Data}
Starting with version 5.1.5, Horde includes a \texttt{horde-remove-user-data} script that can be run on the command line.

\section{Modifying the default script to remove interactivity}
You may want to call the \texttt{horde-remove-user-data} script from another script, providing a user to delete as an argument.<br />
In order to do this, you need to use a modified version of the script.

<pre><code>\#!/usr/bin/env php
<?php
/**
 * This script will delete all user data for a given user.

    \$cli->message('Data removed.', 'cli.success');

You would call the script like this:<br />
\texttt{horde-remove-user-data user@domain.com}

The examples below are for older Horde versions.
