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\releas

How do I make it terminate immediately if one of the calls returns an error code of any level? Basically, I want the equivalent of MSBuild's ContinueOnError=false. batch-file share|improve this question edited Sep 19 '14 at 10:13 Nakilon 19.5k86187 asked Apr 9 '09 at 14:56 Josh Kodroff 10.2k2172125 1 What command shell will be running your script? DOS/Win9x's command.com or Win2k+'s cmd.exe? Since that makes a world of difference, could you please clarify that in an edit of http://stackoverflow.com/questions/734598/how-do-i-make-a-batch-file-terminate-upon-encountering-an-error your question? –Mihai Limbășan Apr 9 '09 at 14:58 add a comment| 6 Answers 6 active oldest votes up vote 182 down vote accepted Check the errorlevel in an if statement, and then exit /b (exit the batch file only, not the entire cmd.exe process) for values other than 0. same-executable-over-and-over.exe /with different "parameters" if %errorlevel% neq 0 exit /b %errorlevel% If you want the value of the errorlevel to propagate outside of your batch file if %errorlevel% neq 0 exit /b %errorlevel% but if this is inside a for it gets a bit tricky. You'll need something more like: setlocal enabledelayedexpansion for %%f in (C:\Windows\*) do ( same-executable-over-and-over.exe /with different "parameters" if !errorlevel! neq 0 exit /b !errorlevel! ) Edit: You have to check the error after each command. There's no global "on error goto" type of construct in cmd.exe/command.com batch. I've also updated my code per CodeMonkey, although I've never encountered a negative errorlevel in any of my batch-hacking on XP or Vista. share|improve this answer edited Apr 4 at 16:06 DangerZone 9411821 answered Apr 9 '09 at 15:03 system PAUSE 17.5k154857 6 Is there a way to state it once for the entire file? "On error goto" or something similar? –Josh Kodroff Apr 9 '09 at 15:29 3 +1 for the negative errorlevel check. Had a script silently fail because of a negative result. –devstuff Sep 16 '10 at 4:37 Carefu
don't make any sense. I'm sure they made perfect sense to me at the time. ;-) Wednesday, October 5, 2011 Common DOS batch file http://armillz.blogspot.com/2011/10/common-dos-batch-file-error-handling.html error handling mistakes I make I write a decent amount of batch scripts now http://www.robvanderwoude.com/errorlevel.php days to automate things on windows server boxes. Unfortunately, I don't do it quite frequently enough to remember all the crazy syntax of DOS commands. One of these errors is error handling. These are the things I commonly need to deal with. I found this page (and site) very helpful for all DOS related stuff: error handling http://www.robvanderwoude.com/errorlevel.php Use "IF %ERRORLEVEL% NEQ 0 SET MYERROR=1" to record whether the previous command resulted in an error code. Alternately, you can check for "IF ERRORLEVEL 1 ..." if you want to look for a specific error level. Be cautious of manipulations with ERRORLEVEL. It's not really an environment variable like other variables. In particular, do NOT ever use "set ERRORLEVEL=5" or similar. It will corrupt any further error checking in use of %ERRORLEVEL% syntax by fixing it at a value. Use "CALL FOO.BAT" instead of just "FOO.BAT" when calling subscripts. Otherwise, when that script completes it will not return to the current script. Use "EXIT /B 1" to return an exit code from your script. If you use "EXIT 1" it will exit the entire command shell, including closing your current window if it's running in one. Consider using SETLOCAL and ENDLOCAL within your script to prevent temporary environment variables from carrying through to outer shells. Below is an example script. :: Sample script with some error handling SETLOCAL SET MYPARAM=%1 if "%MYPARAM%"=="" goto :USAGE CALL .\childscript.bat %MYPARAM% if %ERRORLEVEL% NEQ 0 set MYERROR=1 echo. echo Finished child script. Handling errors now... if %MYERROR%==1 GOTO :ERROR echo It worked! ENDLOCAL set SOME_EXTERNAL_VARIABLE=1 GOTO :EOF :USAGE echo Please provide a command line parameter. EXIT /B 2 :ERROR echo It didn't work, dude. EXIT /B 1 Update: I was wrong about the ERRORLEVEL syntax earlier, so I updated after some testing.

Contact Failed Mail Donate Errorlevels The correct name for errorlevels would be return codes. But since the DOS command to determine the return code is IF ERRORLEVEL, most people use the name errorlevel. Errorlevels are not a standard feature of every command. A certain errorlevel may mean anything the programmer wanted it to. Most programmers agree that an errorlevel 0 means the command executed successfully, and an errorlevel 1 or higher usually spells trouble. But there are many exceptions to this general rule. IF ERRORLEVEL construction has one strange feature, that can be used to our advantage: it returns TRUE if the return code was equal to or higher than the specified errorlevel. This means most of the time we only n
