I've been Googling a bit dos script variables 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 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 77.9k11114179 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 have no error handling.

Though there is nothing wrong with that, it might be a nice challenge to display error messages in the local system language. You don't need to learn new languages to do so, nor will your scripts need to contain megabytes of error messages in several languages. In Windows (and OS/2) there is a simple solution: NET HELPMSG (or NET HELP in OS/2). The following Windows batch file will generate a tab delimited list of all available help and error messages in your local system language: @ECHO OFF TYPE NUL > ErrorMsgAll.txt FOR /L %%A in (0,1,0x4000) DO ( TITLE Trying: NET HELPMSG %%A FOR /F "tokens=*" %%B IN ('NET HelpMsg %%A 2^>NUL') DO ( >> ErrorMsgAll.txt ECHO.%%A %%B ) ) To insert an error message in your batch file, just find a matching message text in the list (AllHelpMsg.txt), write down the number, and insert the following command in your batch file: NET HELPMSG nnnn where nnnn is the error message number you just wrote down.
