To get information about the currently connected user and more MySQL status information, you can call the following command if you are already logged in:

mysql> STATUS;

This will give you an output like that:

--------------

As you can see, you got a lot more information like operation system data, MysSQL version or the number of slow queries.

If you’re only interested in the current versions, you can also use the following command as well:

mysql> SHOW VARIABLES LIKE "%version%";

You’ll get something like that:
