manage mysql-bin.xxxxxx files on mac

[Elim Qiu]

I don't really know how to use those files and so like to know how to
stop populating them. or at least control the number and size of them.

I'm running os x 10.6.8, mysql Server version: 5.1.61-log MySQL
Community Server (GPL)

I tried comment out the line "log-bin=mysql-bin" and those
mysql-bin.xxxxxx files in the data directory. It causes mysql server
starting failure.

So what's advise here? Thanks
