I have a program that creates daily log files that are a lot larger than I would like them to be. I would like to have this so there would be 3 or 4 log files daily. The logs are named logMMDD.txt. I would like to create a batch file to simply rename the log file so that the program creates a new log file and run this 2 or 3 times daily. Can someone help me out as to how to go about grabing the latest file name and renaming it?

Thanks,
Brian

Why don't you try to put a unique sign on the new files, so you can find the file without the sign (the last file) and do whatever you want with it.

Hi Brian,

I'm working on it.

If at first you don't succeed, you're about average.

Try this.

I know it's messy.

::== renLOGS.bat
@ echo off

if not exist logs\*.txt echo nothing to do && goto :eof
set gotEXT=N
dir /b /o-d logs\log????.* | find /i /v "txt">logLIST
for /f %%N in (logLIST) do call :sub1 %%N
dir /b logs\log????.* | find /i "txt">logTXT
set /p currLOG=<logTXT
set currNAME=%currLOG:~0,7%
ren logs\%currNAME%.txt %currNAME%.%nextEXT%
goto :eof

:sub1

if %gotEXT%==Y goto :doneHERE
set last=%1
set lastEXT=%~x1
set lastEXT2=%lastEXT:~1,3%
set /a nextEXT=%lastEXT2%+1
set gotEXT=Y
:doneHERE
goto :eof
:: DONE

If at first you don't succeed, you're about average.

how about appending them to one log file?

this is a log of the contents of c:\

@echo off
cd \
echo %date% >> log.txt && echo dir >> log.txt || echo error
:eof
