If you execute a script via sh script.sh or ./script.sh it is executed
in a sub shell. So every exported variable is only set in all sub-sub
shells.

Try this script to see what I mean

#!/bin/sh

export V=Test
echo $V



Now execute it in a sub shell:

sh script.sh
echo $V

and execute it in the current shell (via sourcing it)

. ./script.sh
echo $V

or

source script.sh
echo $V



Best regards,

Henry
