How to fix "return: can only `return' from a function or sourced script"

[nkshanky]

Do any one how to fix the following error.

return: can only `return' from a function or sourced script

I have 3 scripts

submit_a.ksh
a.ksh
function.ksh


The submit_a.ksh is just a submit script which submits a.ksh at specific time using at command.

Inside a.ksh I refer to function.ksh to calculate some values, if there is an issue with the calculation I use "return 1" to exit the function and send me a notification about the error. While executing the submit script I am receiving the above error.

Appreciate inputs.

Thanks

I am submitting the job using at command. While submitting it reports "warning: commands will be executed using /bin/sh". - (BASH)

Any one know how to change this so it picks /usr/bin/sh.

thanks

State it in the first line of the script. Instead of it saying this:

#! /bin/bash

have it say this:

#! /usr/bin/sh

At least I THINK that is what you need to do.
