It isn’t always pretty, but, it gets the job done. i didn't try this out, but it should work : if %ERRORLEVEL% GEQ 1 EXIT /B %ERRORLEVEL%. –Viktor Fonic Jul 18 '14 at 11:24 1 At least in Windows, %ERRORLEVEL% otherwise .bat eats the errorlevel and app1 never knows. This was an issue I fought with a few months ago on an embedded system running DOS (real DOS, not CMD.EXE). http://jscience.net/batch-file/windows-command-script-return-code.html
To execute a follow-on command after sucess, we use the && operator: SomeCommand.exe && ECHO SomeCommand.exe succeeded! This type of compare ("%errorlevel%=="0") becomes dubious at best.B.bat can use the exit statement to pass a return code (errorlevel) back to a.bat.QuoteQuits the CMD.EXE program (command interpreter) or the current If executed from outside a batch script, it will quit CMD.EXE exitCode specifies a numeric number. if /B is specified, sets ERRORLEVEL that number.
SET /A ERROR_HELP_SCREEN=1 SET /A ERROR_FILE_NOT_FOUND=2 SET /A ERROR_FILE_READ_ONLY=4 SET /A ERROR_UNKNOWN=8 This gives me the flexibility to bitwise OR multiple error numbers together if I want to record numerous problems A word for something that used to be unique but is now so commonplace it is no longer noticed Implementing realloc in C How do I install Python 3.6 using apt-get? For example: myProgram.exe && echo Done! A very simple way to halt on error is to use the EXIT command with the /B switch (to exit the current batch script context, and not the command prompt process).
To close an interactive command prompt, the keyboard shortcut ALT + F4 is an alternative to typing EXIT. share|improve this answer answered Apr 19 '13 at 5:07 Sam Jones 4701718 3 it could be even better if you returned the same error back to app1. Thanks. –Dlongnecker Aug 10 '10 at 21:24 2 Oh, for posterity, to make it stop on error, after :somethingbad, use a "pause" command –Dlongnecker Aug 11 '10 at 20:08 2 Cmd Set Errorlevel Before posting on our computer help forum, you must register.
CMD.exe allows you to set it but then from that point on the variable is mostly meaningless. This type of compare ("%errorlevel%=="0") becomes dubious at best.B.bat can use the exit statement to pass a return code (errorlevel) back to a.bat.QuoteQuits the CMD.EXE program (command interpreter) or the current Jumping to EOF in this way will exit your current script with the return code of 1. If quitting CMD.EXE, sets the process exit code with that number.That's exactly what I was looking for!Thanks a lot!Works like a charm!Gabor Logged billrich Guest
