batchacha: sametime chatlog filer

i wrote this script to file previous month’s sametime chat logs (we used the reference chat logging dll which writes to text files). it places the chat logs in a directory hierarchy of year (4 digits) and month (2 digits with padding).

stcf.bat:

@ECHO OFF
CLS
:: SameTime Chatlog Filer (stcf)
:: purpose: Moves previous month's logs into sub dir e.g. Jan 2009 logs into
::          a directory called d:\chatlogs\2009\01
SETLOCAL EnableDelayedExpansion
SET chatLogsDir=D:\CHATLOGS\

SET DD=%date:~0,2%
SET MM=%date:~3,2%
:: Testing for first and last months of the year
::SET MM=01
::SET MM=12
SET YYYY=%date:~6,4%

:: Work out previous month's log file name, as we'll only be moving these log files
IF "%MM%" == "01" SET prevMon=DEC

IF "%MM%" == "01" (
	SET prevMM=12
