I'm confused. The return 1 statement can only be used in a function or a sourced shell script. This doesn't apply here?
Are you sure you are using bash for this? If you do not specify:
as the very first line of test.sh then you are using
which is a POSIX shell, not necessarily bash.
will tell you ( inside test.sh) what shell you are using.
So help us to help you with some more information.
PLUS
a return code of zero means success in the shell, any other number is a fail.

Sorry I left out the bash header. I am using Bash.
I have several load.sh scripts, and want to call them all from one test.sh script.
Each load.sh script calls a C++ function that returns an error code (0 means EXIT_SUCCESS).
Is there a way to pass the error code from C++ function, to load.sh, to test.sh?
And then test.sh use the returned error code in a conditional statement?
Thanks.
tests.sh:
load.sh:
from command line:
I was expecting it to output "1".
The bash shell script:
does not make any attempt to run the utility named main. And, as jim mcnamara already said, you don't use return to exit from a bash shell script. According to the standards, using return when you are not inside a function or inside a script invoked by the . command produces unspecified results. Running that script with bash prints two diagnostic messages:
and exits with exit code 1. Running that same script with ksh produces no diagnostics and exits with exit code 0.
If you just want a shell script that invokes a utility named main and exits with an exit code matching that returned by main, you can use any of the following:
or:
or:
or:
or, more simply, just:

I tried the scripts you suggested in my load.sh file, but get the same result.
load.sh:
From command line:
Bash is not giving may any messages when I run tests.sh. Yet jim mcnamara and you are seeing messages.
Is that something I can turn on?
However, I do get a message when I run load.sh directly: ---------- Post updated at 03:20 AM ---------- Previous update was at 03:15 AM ----------
Update:
Adding "./" to load.sh fixed load.sh:
From terminal:
But tests.sh still prints 0:
