I need a DOS batch script which calls another batch script, but need conditions in the script to make sure:-

1) the script calls the other batch script successfully
2) the script exists if the script fails

Thanks

Try something like this... is that what you mean?

Steve

@echo off
REM change to current directory of this batch file, mapping drive if needed for a UNC
pushd "%~dp0"
  if not exist 2.cmd (
    echo The batch file was not found, exiting
    exit /b
  )

  call 2.cmd 2>NUL

  if errorlevel 1 (
    echo The other batch file was found OK and the error level was %errorlevel%
    exit /b
  ) ELSE (
    echo The other batch file was found OK and showed no error
  )

popd

Open in new window


and the second batch file then you can return the error code to the first with exit /b 1 etc., i.e.

exit /b 0 = OK
exit /b 1 = returns 1
exit /b 2 = returns 2
exit /b %errorlevel% = returns the errorlevel of the command before it

@echo off
echo Do your stuff here in batch 2
echo An error level returned on the exit statement as you need:

exit /b 1

Open in new window

Crossed posts there with Qlemo of course... basically the same difference but I laid mine out a bit more wordily to show you other options.

Why only Steve got points (and why a "B" grade only)? Both solutions are comparable and without much of a difference.
