Shell Script Error Handling
Batch Script up vote 0 down vote favorite We have some error handling setup in our scripts as shown: set ret = %ERRORLEVEL% if %ERRORLEVEL% == 0 GOTO PPCOK if not %ret% == 0 GOTO ERROR1 Someone else wrote the above, I however have a few concerns about it actually working properly. I have read that if you do a check for ERRORLEVEL = 0 it actually expect script error handling is checking if the errorlevel is 0 or higher. My assumption is that it would always go to the PPCOK label? Also, most examples on the web use "IF ERRORLEVEL 1" or some show "IF %ERRORLEVEL% EQU 1" and above uses "IF %ERRORLEVEL% == 0" I am wondering if there is a valid case for choosing which of these three methods should be used? On a side note I am not sure why they stored the errorlevel in another variable and used it on the second if statement rather than just doing another IF NOT %ERRORLEVEL% ... windows batch-file share|improve this question asked Jan 31 '14 at 17:11 Kairan 1,685143770 No, if %ERRORLEVEL% == 0 will only be true if the error level is actually zero. This method is usually preferable in my opinion, although it will fail in the pathological case where someone has created an environment variable named ERRORLEVEL. You are right in thinking that there is no need for the ret variable, in fact the second if statement is entirely redundant, you could just say GOTO ERROR1. –Harry Johnston Feb 4 '14 at 2:56 add a comment| 1 Answer 1 active old

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

Alan Wanwierd Ranch 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 error handling using the %ERRORLEVEL% variable to crudely trap my errors, but my outer calling batch 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 script error handling ...Completed Batch3, %ERRORLEVEL% goto end :failed echo ....ERROR Please check logs 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?
