Remove MySQL Binary Log with PURGE BINARY LOGS Statement

A while ago I had a problem whereby on a very busy mysql cluster,

I had a problem whereby mysql was filling up /var. 

To fixed the problem, I made use of Linux's find and its ability to find 

all mysqls binary logs older than a certain date. 

Ive now discovered 'PURGE BINARY LOGS'.  

Heres my examples:

mysql -u username -p
mysql>PURGE BINARY LOGS TO 'mysql-bin.000005';

shell> mysql -u username -p
mysql> PURGE BINARY LOGS BEFORE '2011-08-13 00:00:00';

For more information.
