Batch Script If Statement
Batch Programming, Error Handling, and Start Command up vote 6 down vote favorite I am just starting to learn how to script. I'm trying to understand how the system handles Error Levels and how they can be used in error handling. I know there is a difference between the environment variable %ERRORLEVEL% and the Error Level of the system. If I understand this dos batch error handling correctly, then the If ERRORLEVEL 1 code would check the environment variable before it checks the error level of the previous command. So, in my program I am trying to interface a startup/stop script that will start/stop all scripts of a given machine (for testing I'm just using one application notepad.exe as an example). I have two wrapper scripts that will either start up or stop the applications by passing arguments to the independent script. If there is an error in the independent script, it will set the errorlevel using the EXIT /B n command. Once control is returned to the calling script, it will go to an error handling script if the exit status is non-zero. At first I was setting the %ERRORLEVEL% to zero manually and then testing for an error after a START or TASKKILL command. But then I read that clearing %ERRORLEVEL% with SET ERRORLEVEL= is a better method. My issue comes in when I try to start the app with START "" notepad.exe Whenever I test the errorlevel after this command it is always greater than or equal to 1 unless I us

For safety reasons each script must return non zero value if error detected (to enable error detection if bat script is executed from other program as separate process). To check if error occured after execution of DOS command or after call of external program use this (tested on Windows XP): IF %ERRORLEVEL% NEQ 0 GOTO ERROR_HANDLER where ERROR_HANDLER is label (jump point) in your bat script which contains error handling part of code. Complete example: copy N files from location A to the B and after each step check for error, if error occured print 'Error' otherwise 'Sucess'. Note: 'exit 1' will cause command prompt to close, to avoid this, remove command 'exit 1':
This Site Careers Other all forums Forum: General Computing DOS batch file error handling? Alan Wanwierd Ranch https://coderanch.com/t/132733/gc/DOS-batch-file-error-handling Hand Posts: 624 posted 8 years ago I'm writing a batch file to join together a bunch of processes triggered by batch files... When everything works its great, but my error handling sucks. I've tried using the %ERRORLEVEL% variable to crudely trap my errors, but my outer calling batch error handling file never goes into error: call Batch1.bat if %ERRORLEVEL% NEQ 0 goto failed echo ...Completed Batch1, %ERRORLEVEL% call Batch2.bat if %ERRORLEVEL% NEQ 0 goto failed echo ...Completed Batch2, %ERRORLEVEL% Call Batch3.bat if %ERRORLEVEL% NEQ 0 goto failed echo ...Completed Batch3, %ERRORLEVEL% goto end :failed echo ....ERROR Please check logs script error handling for further details, %ERRORLEVEL% :end endlocal The output I end up with is: ...Completed Batch1, 0 .......BATCH2 ERRROR, Please check logs for details ...Completed Batch2, 0 ...Completed Batch3, 0 Obviously the Batch2.bat file is erroring - but the error is not being passed back. Is there a way around this?
