Get the application exit code from a Windows command line?

rajeshkumar created the topic: get the application exit code from a Windows command line?

Two ways…

(1) The results are stored in a pseudo environment variable named errorlevel so…

echo Exit Code is %errorlevel%
(2) and a special syntax of the if command:

if errorlevel
see if /? for details.

For Example

@echo off
my_nify_exe.exe
if errorlevel 1 (
echo Failure Reason Given is %errorlevel%
exit /b %errorlevel%
)

:: Exit if a required file is missing
@echo off
If not exist MyimportantFile.txt Exit /b
Echo If we get this far the file was found

:: Set the error level to 5
@echo off
call :setError
echo %errorlevel%
goto :eof

:setError
Exit /B 5

To make this more flexible you can change the subroutine to set any errorlevel like this:

:setError
Exit /B %1

Now you can call the subroutine: call :setError 6 replacing 6 with whatever value you need the errorlevel to be set to.

EXIT is an internal command.
