Getting return value of main()

I'm calling a program from a bash script and was just wondering
how I could get the return value from the program and put it into a variable in my script.

Thanks

I think (meaning I could be wrong) that the last program to execute's return value is in the environment variable $?

you probably can use it as is...

Hi.

The return value of a application run from a script is stored in the special return value '$?'

Example:

#!/bin/sh
someapp
echo "return value of someapp was: " $?
