Getting errorlevel from a called batch file

Question

I have several batch files that I call from a parent batch file. I need to trap if there are any errors that occur in the child batch files. When a child batch file makes a call to an exe file, I am able to trap the error in the child batch file just fine. How do I surface it up to the parent batch file?

Answer 1

Exit with:

exit /b errorlevel

In your child batch script.
