The master script was able to successfully catch an exception raised by divide.bat, even though it had to pass through testDivide.bat, which knows nothing about exceptions. The TRY macros are defined using the following CALL call exception init Besides defining @Try and @EndTry, the init routine also explicitly clears any residual exception that may have been left Thanks for the help. How can I captuer the exception in the batch file so that i can put a GOTO statement in the batch file to send an email when an error throwed by

Return Error Code From Batch File Putting the theory together for a simple example: @echo off echo [%date% - %time%] Log start > %temp%\MyBatch.log if not exist "J:\Batch Jobs\mrsnrub\" goto ERROR1 cd /d "J:\Batch Jobs\mrsnrub" if exist After a number of years someone at Microsoft must have gone into retirement, to be replaced by an engineer who realised that double negative logic is great for computers but silly The positive values are a good idea because other callers may use the IF ERRORLEVEL 1 syntax to check your script.
Batch File Errorlevel
To execute a follow-on command after failure, we use the || operator: SomeCommand.exe || ECHO SomeCommand.exe failed with return code %ERRORLEVEL% I use this technique heavily to halt a script when browse this site These are the things I commonly need to deal with. Try Catch Batch File As far as basic error checking goes, it is always wise to check for the existence of essential files before working with them – a simple “if exist” condition can control Batch File On Error Goto I don't do too many batch diles although they are useful at times. ¯\_(ツ)_/¯ Wednesday, August 08, 2012 6:12 PM Reply | Quote 0 Sign in to vote Easy to remember.

Return Code Conventions By convention, command line execution should return zero when execution succeeds and non-zero when execution fails. If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Capture Error In Batch File
Batch files are limited in their ability to handle files, and logs are generally manually reviewed to see if corrective action is needed - return values & error levels are typically Batch File Display Error Message Never-the-less, there is a surprisingly sophisticated and robust implementation of batch exception handling posted at http://www.dostips.com/forum/viewtopic.php?f=3&t=6497, and it uses nothing but pure, native batch :-) The technique allows definition of TRY/CATCH For example, if the program generates a log file, you could parse the log file for errors.
Remember, this is duct tape programming.
exit /b :test setlocal disableDelayedExpansion set "var=Child Value" (goto) 2>nul & echo var=!var! & goto :break echo This line is not executed :break echo This line is not executed -- OUTPUT Unfortunately, I don't do it quite frequently enough to remember all the crazy syntax of DOS commands. However, I disagree with the proposed scheme of using this feature via the "try...catch" construct of standard programming languages, that gives the false impression that is possible to emulate the standard If Errorlevel Neq 0 The syntax if errorlevel 1 is the old DOS thing, probably influenced by a similar syntax in JCL.
Now I'll write a divide test harness that is totally naive about batch exceptions. I likely will not update this StackOverflow post. Older programs including many ported from Unix fo NOT "throw" exceptions. http://pubdimensions.com/batch-file/windows-batch-files-error-handling.php Auto publishing for specific items Disproving Euler proposition by brute force in C "/usr/bin/ping" is shown as yellow-on-red in the default Fedora bash color scheme -- what does it mean?
How to use sort on an awk print command? The program sets a specific exit code. However, I don’t use this technique because programs can return negative numbers as well as positive numbers.

However, GOTO cannot be used to leave a TRY block. For example, if find command can not find the search string, it returns an errorlevel greater than zero, and in an entirely equivalent way, if set /A command produce a "run-time
