How can one batch file get the exit code of another?

I have two batch files, task.bat and runtask.bat. The runtask.batcalls task.batand I would like runtask.bat to get the exit code of task.bat into a variable. How could this be done?

task.bat:

@echo off
set errorlevel=1

runtask.bat

...
CMD /C task.bat
set taskexitcode=????

Just swap CMD /C for call.

task.bat:

@echo off
set errorlevel=15

runtask.bat

call task.bat
set taskexitcode=%errorlevel%
echo %taskexitcode%

Output

Worked like a charm, thanks. It also allows variables to be set in `task.bat` and read in `runtask.bat`. Thanks very much! – James Jan 11 '13 at 13:26
Great, no worries. I didn't actually know about the variables, nice :) – Bali C Jan 11 '13 at 14:32
The exit command has an `/B` switch for setting the exit code for a batch script. – William Bettridge-Radford Jan 11 '13 at 18:57

@william-bettridge-radford: `/B` determines whether `exit` terminates the script or `cmd.exe` also. It has nothing to do with the exit code. – Andreas Jan 12 '13 at 12:19

`EXIT /?` lists `EXIT /B [exitCode]`; it sets an exit code and returns from the subroutine or script. – William Bettridge-Radford Jan 12 '13 at 17:16

I had a batch script in Teamcity pipeline and it did not exit after it's child script did exit with code 1.

To fix the problem I added this string IF %ERRORLEVEL% NEQ 0 EXIT 1 after the child script call.

main-script.bat

...some code
call child-script.bat
IF %ERRORLEVEL% NEQ 0 EXIT 1
...some code

After the child script call, exit result is save to %ERRORLEVEL%. If it did exit with error the value would be not equal to 0. So we check this and if it is the case we exit with code 1 (error).

The accepted answer is correct, but if you are using call to call another batch script, and that second batch script is using SetLocal, you may need to use a parsing trick to accomplish this. If you are running into this, add the following code before your exit b:

ENDLOCAL&set myvariable=%myvariable%

Now the value of myvariable is made available to the calling context and you can see the value in the other script.
