Howto display currently used db name into mysql command prompt

For people like me, who uses mysql command prompt every day, knowing exaclty what db is currently in use  is sometimes crucial. Dealing with one or two is not a problem, but constantly switching between 15-20  ... Well thats another situation.

Hi all,

Yesterday tried to upgrade my funtoo box. The core package, sys-apps/shadow was upped at its current rev - sys-apps/shadow-4.1.5-r2 ... And the problems began.
