MySQL Command Line Client

Install Wordpress, Joomla, Gallery2, Moodle on my laptop, and try to sync users among these applications by Jfusions plugin for Joomla, then make a mess. After unssuccessfully reinstall Gallery2 several times, I have strong desire to look into the MySQL database, the only client available is "MySQL Command Line Client". So here we go:
