@CharlesB You do need the quotes for echo. What makes you think otherwise?

I don't need them, I can echo $test and it works (it outputs the value of $test)

@CharlesB It only outputs the value of $test if that does not contain multiple spaces anywhere. Try the program in my answer for an illustration of the reason.
