#!/bin/bash

function return_func () {
echo “I’m returning, but not exiting . . .”
return 1
echo “This will not be displayed :-)”
}

function exit_func () {
echo “I’m exiting . . .”
exit 0
echo “This will not be displayed :-)”
}

echo
echo “Before returning.”
echo
return_func
if [ $? -eq 1 ]; then
echo
echo “Before exiting.”
echo
exit_func
fi
echo
echo “And you will not see this on execution”
exit 2

Check the output status using $? immediately after the execution of the above script. I hope that’s clear.

Could you explain with some brief examples.
