I've been Googling 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.

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 Fool

Join them; it only takes http://stackoverflow.com/questions/1164049/batch-files-error-handling a minute: Sign up Does Windows batch support exception handling? up vote 13 down vote favorite 7 Does Windows batch programming support exception handling? If not, is there any way to effectively emulate exception handling within batch files? I would like to be able to "throw an exception" anywhere within a batch script, at any CALL level, and have the CALL http://stackoverflow.com/questions/31445330/does-windows-batch-support-exception-handling stack popped repeatedly until it finds an active "TRY block", whereupon a "CATCH block" can handle the exception fully and carry on, or do some cleanup and continue popping the CALL stack. If the exception is never handled, then batch processing is terminated and control returns to the command line context with an error message. There are already couple posted ways to terminate batch processing at any CALL depth, but none of those techniques allow for any structured cleanup activity that would normally be provided within other languages via exception handling.

Never in my wildest dreams did I ever think effective exception handling could be hacke
Checking and Running as Scheduled Tasks ★★★★★★★★★★★★★★★ Paul Adams (ex-MSFT)June 6, 201016 0 0 0 Batch files may be considered “old https://blogs.technet.microsoft.com/mrsnrub/2010/06/06/batch-files-basic-error-checking-and-running-as-scheduled-tasks/ hat” by a lot of people (or a complete mystery to the https://coderanch.com/t/132733/gc/DOS-batch-file-error-handling younger ones!) but they are sometimes still the easiest way to execute simple jobs as they have practically no requirements other than a command shell process to run within – yes there is a strong probability that a script could achieve an identical (or at least error handling equivalent) result, but the fact is that it will be more complex and therefore longer to create and administer. Something that trips up a fair number of people is the difference between double-clicking a .BAT file and scheduling it as a task to run at a certain time, on a trigger or on a schedule – it can seem batch file error that the batch file just simply does not run at all, and the return code sent back to the Task Scheduler is often 0x2, “path not found”, even though the file most definitely is there. When you double-click a .BAT or .CMD file through Explorer, a cmd.exe process is started to provide the environment in which it will run. The credentials used are your own (or more correctly, inherited from the Explorer process). The “current working directory” is set to that where the batch file lives. When the Task Scheduler service starts the same batch file it actually invokes an instance of cmd.exe (as SYSTEM impersonating the user whose credentials are defined in the task) to carry out the process and waits for it to exit with a return code – the current working directory for this process is not that of the batch file, but that of cmd.exe itself. i.e. %windir%\system32 Now, if your batch file assumes that you launched it through Explorer or from an existing command prompt wit
This Site Careers Other all forums Forum: General Computing DOS batch file error handling? Alan Wanwierd Ranch Hand Posts: 624 posted 8 years ago I'm writing a batch file to join together a bunch of processes triggered by batch files... When everything works its great, but my error handling sucks. I've tried using the %ERRORLEVEL% variable to crudely trap my errors, but my outer calling batch file never goes into error: call Batch1.bat if %ERRORLEVEL% NEQ 0 goto failed echo ...Completed Batch1, %ERRORLEVEL% call Batch2.bat if %ERRORLEVEL% NEQ 0 goto failed echo ...Completed Batch2, %ERRORLEVEL% Call Batch3.bat if %ERRORLEVEL% NEQ 0 goto failed echo ...Completed Batch3, %ERRORLEVEL% goto end :failed echo ....ERROR Please check logs for further details, %ERRORLEVEL% :end endlocal The output I end up with is: ...Completed Batch1, 0 .......BATCH2 ERRROR, Please check logs for details ...Completed Batch2, 0 ...Completed Batch3, 0 Obviously the Batch2.bat file is erroring - but the error is not being passed back. Is there a way around this?
