How to debug a bash function that returns a value, and how to add newlines to a variable?

Question

I\'m in a bash crash course today.

This is a bash function that returns a value, via echo:

#!/bin/bash
get_hello_name() {
  echo \'Hello $1!\'
}
msg=

You might want to call it with a double quote echo "$x" However if you would want to explicitly show what you typed inside, also known as literal expression use a single quote echo '$x'
