Hi,

is it possible to return the errorlevel also if I pipe the output of a script into a logfile:

test1.bat:

 call test2.bat 2>&1 | tee log.txt
 echo ERRORLEVEL: %ERRORLEVEL%

test2.bat:

 exit /B 1

Output when calling test1.bat:

 ERRORLEVEL: 0

The errorlevel is always 0.

The problem is, I want to call another script inside my script where the output should be redirected synchronously with the output shown in the command line, therefore a simple > is not enough for me. I tried several ideas, but result is that the pipe always seems to destroy the given error-level... :(

Can you give me any further suggestions?

Thanks in advance... :)
