It seems like the MS-DOS internal commands do not return an error code. Can someone confirm that? How does a script that uses http://stackoverflow.com/questions/6500314/do-ms-dos-built-in-commands-return-an-error-exit-code these commands know if the commands succeed or fail in order to decide the next step? The easiest way is to read their return code, if it is returned. Thanks in advance. batch-file dos ms-dos windows-scripting share|improve this question asked Jun 28 '11 at 0:08 Duat Le 3,37811218 I had a comment here stating DOS commands do return error codes, but I see now from the answers and my own testing that it's not an always thing for all commands (and I suppose that may relate to many "DOS commands" actually just calling external executables in the %PATH%, which executables apparently may differ in properly returning error codes. I wouldn't put it past cmd internal commands to be inconsistent with error codes, either, though ;) –Alex Hall Feb 7 at 19:31 add a comment| 4 Answers 4 active oldest votes up vote 16 down vote accepted No, it appears not to. If you echo %errorlevel% after either a successful or failed rmdir, you get 0 in both cases: c:\pax> mkdir qqq c:\pax> rmdir qqq c:\pax>

Let me try to explain it in a different way:a.bat calls b.bat and when b.bat completes, a.bat continues with steps depending on whether b.bat succeeded or failed.a.bat:Code: [Select]rem some code here
call b.bat
if "%errorlevel%=="0" goto success
:failure
rem do something
goto end
:success
rem do something else
:endWhat would b.bat look like for a.bat to work?Thanks again!Gabor Logged fireballsApprentice Code:TerminalThanked: 3 Re: How to return success/failure from a batch file? « Reply #3 on: September 09, 2008, 04:23:57 PM » If one of b.bat's commands fails because of an error then it will set errorlevel to 1 and exit the batch program, returning to a.bat.What is wrong with the code you provided below?FB Logged Next time google it.
