Re-opening files in Batch

For definitely not malicious reasons, I need to have a batch file always open. I have some base code: 

:b

echo off

tasklist /fi "imagename eq cmd.exe" |find ":" > nul

if errorlevel 1 taskkill /f /im "game.bat"&start game.bat

goto b

And it works fine if want notepad.exe or blah.txt and etc. Except for batch files, as the program itself is a batch file, the system sees cmd.exe is already open.

It works except for batch files, as the system sees cmd.exe is already open.

  1. Give your batch file a Title by adding the following command to game.bat:

    title %~nx0

  2. Check if game.bat is running by using tasklist with /v option:

    :b
@echo off
tasklist /v | find "game.bat" > nul
rem errorlevel 1 means game.bat is not running, so start it
if errorlevel 1 start game.bat
rem timeout to avoid excessive processor load
timeout 60
goto b
