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
Batch File Error Handling Errorlevel
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\sokrates.exe" D:\SPCDeployIF %ERRORLEVEL% NEQ 0 GOTO ERROR_HANDLER copy /Y "D:\tool\AdminTool\release\db_actualize.dll" D:\SPCDeployIF %ERRORLEVEL% NEQ 0 GOTO ERROR_HANDLERecho.echo Sucess!!!GOTO QUIT:ERROR_HANDLERecho.echo Error occured!!!exit 1:QUITecho.

Programming Error Handling Best Practices
handling using ERRORLEVEL in Windows 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 http://www.mandrilo.com/index.php/mini-how-to-archive/149-windows-dos-batch-programming-error-handling 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 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 http://stackoverflow.com/questions/21485988/error-handling-using-errorlevel-in-windows-batch-script 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 1,680143770 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 oldest votes up vote 0 down vote accepted Batch is sensitive to spaces in a SET statement. SET FLAG = N sets a variable named "FLAGSpace" to a value of "SpaceN" IF ERRORLEVEL n is TRUE if errorlevel is n or greater than n. IF ERRORLEVEL 0 is therefore always true. IF NOT ERRORLEVEL 1 is a test for errorlevel=0. So is IF %ERRORLEVEL%==0, exept that the former can be used within a block but the latter cannot. share|improve this answer answered Jan 31 '14 at 17:17 Magoo 38.4k32649 Actually, the error level is treated as a signed quantity. So if errorlevel 0 is not always true, and if not e
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 https://blogs.technet.microsoft.com/mrsnrub/2010/06/06/batch-files-basic-error-checking-and-running-as-scheduled-tasks/ (or a 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 – 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 error handling and therefore longer to 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 batch file error to the Task Scheduler is often 0x2, “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 a
