Debugging Challenge

Remember batch? (Batch)

Previously on Dr. Lambda’s blog: I have devised a series of debugging challenges, some are easy, some are really hard, all come from real live systems. Good luck!

The Challenge

• 1 point if you can spot where the error is.
• +1 point if you can explain why.
• +2 points if you can explain how to fix it.

@Echo off

set direct=1
echo %cmdcmdline% | find /i "%~n0" >nul
if not %errorlevel% == 1 set direct=0

REM powershell.exe -file .\AdHocScripts\FlushBlobCache.ps1
Set e=%errorlevel%
if not %e% == 0 goto error

powershell.exe -Version 2 -file .\AdHocScripts\FarmIISReset.ps1
Set e=%errorlevel%
if not %e% == 0 goto error

goto success

:error
    Echo ERROR, errorlevel %e%
    if %direct% == 0 pause else exit %e%
    goto end
:success
    Echo done
    if %direct% == 0 pause
:end
