If FILENAME.9 exists, it is deleted. Can be used to keep log files small and managable, and delete old ones. The code is not pretty, I could not get it work with loops. If anyone has a better way of doing this, please let me know! :-)

Usage:

rollLog LOGDIRECTORY LOGFILENAME

For instance, if you have a log at c:\log\at.log, you can run:

rollLog c:\logs at.log

Afterwards, you have one file named c:\logs\at.log.0. The next time you run it (and there has been something written to at.log) you get two files, at.log.0 and at.log.1.

The rollLog.cmd file is here!
