Here's how to automatically rotate Abyss web server logs by month in 32-bit Windows.

Assumptions:

1. The Abyss web server log file is in C:\Program Files\Abyss Web Server\log\access.log.
2. Windows has a yyyy/mm/dd date format from its Date and Time Control Panel applet.
3. Windows has a fully functioning Task Scheduler (all related services are running).

Steps:

1. Create a batch file with the following contents.

   for /f "tokens=1-3 delims=/ " %%a in ("%DATE%") do (
   set yyyy=%%a
   set mm=%%b
   set dd=%%c)
   
   rem the order of %%a, %%b and %%c are system dependent! (control-panel, date/time settings)
   
   echo %dd%
   echo %mm%
   echo %yyyy%
   
   if not exist "ac%yyyy%%mm%.log" (
   net stop AbyssWebServer
   rem (move the log file in another folder, example: access.22.11.2005.log)
   ren "access.log" "ac%yyyy%%mm%.log"
   rem (Abyss start and create a new log file)
   net start AbyssWebServer
   )
   pause

2. Create a multiple time scheduled task (or make it run daily) to run the above batch file.
3. Test the damn thing and smile to the world around you to make it a little better.
