Shortcode fbshare

Hi,

I would like to use the shortcode fbshare but there seems to be a problem. This is my code:
<?php echo do_shortcode('[fbshare]'); ?>

It just displays [fbshare] on the front-end, just as plain text.
Does anyone has an idee?
Do i have to install a plugin to use these shortcodes?

Thanks.
