I've been Googling dos batch error handling a bit for a general error handling approach and can't find anything really useful. Basically if any thing goes wrong I want to stop and print out what went wrong. Can anyone give me any pointers? batch-file share|improve this question edited Apr 29 '14 at 11:28 John Saunders 138k20175321 asked Jul 22 '09 at 9:15 bplus 2,87494574 add a comment| 5 Answers 5 active oldest votes up vote 34 down vote I generally find the conditional command
Batch File Error Handling Tutorial
concatenation operators much more convenient than ERRORLEVEL. yourCommand && ( echo yourCommand was successful ) || ( echo yourCommand failed ) There is one complication you should be aware of. The error branch will fire if the last command in the success branch raises an error. yourCommand && ( someCommandThatMayFail ) || ( echo This will fire if yourCommand or someCommandThatMayFail raises an error ) The fix is to insert a harmless command that is guaranteed to succeed at the end of the success branch. I like to use (call ), which does nothing except set the ERRORLEVEL to 0. There is a corollary (call) that does nothing except set the ERRORLEVEL to 1. yourCommand && ( someCommandThatMayFail (call ) ) || ( echo This can only fire if yourCommand raises an error ) See Foolproof way to check for nonzero (error) return code in windows batch file for examples of the intricacies needed when using ERRORLEVEL to detect errors. share|improve this answer edited Apr 29 '14 at 11:24 answered Jun 13 '13 at 11:27 dbenham 78k11114180 Would u mind to provide a simple example with copy or del commands, pls? –Dimi Dec 17 '13 at 14:00 Much nicer than keeping track of ERRORLEVEL, thanks! –kaveman Oct 24 '14 at 18:20 add a comment| up vote 6 down vote Other than ERRORLEVEL, batch files ha

I'm trying to understand how the system handles Error Levels and how they can be used in error handling. I know there is a difference between the environment variable %ERRORLEVEL% and the Error Level of the system. If I understand this correctly, then the If ERRORLEVEL 1 code would check the environment variable before it checks the http://stackoverflow.com/questions/6498460/batch-programming-error-handling-and-start-command error level of the previous command. So, in my program I am trying to interface a startup/stop script that will start/stop all scripts of a given machine (for testing I'm just using one application notepad.exe as an example). I have two wrapper scripts that will either start up or stop the applications by passing arguments to the independent script. If there is an error in the independent script, it will set the errorlevel using the EXIT /B n command. Once control is returned to the calling script, it will go to an error handling script if the exit status is non-zero. At first I was setting the %ERRORLEVEL% to zero manually and then testing for an error after a START or TASKKILL command. But then I read that clearing %ERRORLEVEL% with SET ERRORLEVEL= is a better method. My issue comes in when I try to start the app with START "" notepad.exe Whenever I test the errorlevel after this command it is always greater than or equal to 1 unless I use SET ERRORLEVEL=0 before I run the start command. I have inserted the code for the four scripts below. Any insight and advice would be greatly appreciated. appstart.bat: @echo off :: Script fo

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\sok
