Append code into wp-config.php
<p>We have multiple wordpress sites and need to update the wp-config for w3 total cache. We have to append <code>define('WP_CACHE', true);</code> into the wp-config.php file. Is it possible to do this via ssh. I don't want to have to go in and open each config file and add it myself.</p>

<p>Your help will be much appreciated.</p>
