Batch File Error Handling Tutorial
if error is detected after each step. 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': @ECHO OFFREM COPY all copy /Y D:\exe\appserver\release\appserver.exe" D:\AppServerDeployIF %ERRORLEVEL% NEQ 0 GOTO ERROR_HANDLER copy /Y "D:\exe\sokrates_spc\release

Bash Error Handling
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 http://www.mandrilo.com/index.php/mini-how-to-archive/149-windows-dos-batch-programming-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 https://coderanch.com/t/132733/gc/DOS-batch-file-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?

Checking and Running as Scheduled Tasks ★★★★★★★★★★★★★★★ Paul Adams (ex-MSFT)June 6, 201016 0 0 0 Batch files may be considered “old hat” by a lot of people (or a https://blogs.technet.microsoft.com/mrsnrub/2010/06/06/batch-files-basic-error-checking-and-running-as-scheduled-tasks/ complete mystery to the younger ones!) but they are sometimes still the easiest way to execute simple jobs as they have practically no requirements other than a command shell process to run within http://www.tomsguide.com/forum/242329-49-batch-programming-error-handling-start-command – yes there is a strong probability that a script could achieve an identical (or at least equivalent) result, but the fact is that it will be more complex and therefore longer to error handling create and administer. Something that trips up a fair number of people is the difference between double-clicking a .BAT file and scheduling it as a task to run at a certain time, on a trigger or on a schedule – it can seem that the batch file just simply does not run at all, and the return code sent back to the Task Scheduler is often 0x2, error handling bat “path not found”, even though the file most definitely is there. When you double-click a .BAT or .CMD file through Explorer, a cmd.exe process is started to provide the environment in which it will run. The credentials used are your own (or more correctly, inherited from the Explorer process). The “current working directory” is set to that where the batch file lives. When the Task Scheduler service starts the same batch file it actually invokes an instance of cmd.exe (as SYSTEM impersonating the user whose credentials are defined in the task) to carry out the process and waits for it to exit with a return code – the current working directory for this process is not that of the batch file, but that of cmd.exe itself. i.e. %windir%\system32 Now, if your batch file assumes that you launched it through Explorer or from an existing command prompt with the current working directory set to its own location, you can run into problems. One simple way to verify if your batch file should work as a scheduled task is to call it from an existing cmd.exe process from a different current working directory (such as your profil
