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 17.4k154857 6 Is there a way to state it once for the entire file?

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\sokrates.exe" D:\SPCDeployIF %ERRORLEVEL% NEQ 0 GOTO ERROR_H
don't make any sense. I'm sure they made perfect sense to me http://armillz.blogspot.com/2011/10/common-dos-batch-file-error-handling.html at the time. ;-) Wednesday, October 5, 2011 Common DOS batch file error handling mistakes I make I write a decent amount of batch scripts now days to automate http://www.tomshardware.com/forum/263353-45-batch-file-error-trapping 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 error handling handling. These are the things I commonly need to deal with. I found this page (and site) very helpful for all DOS related stuff: 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 batch error handling 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 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_E
