I believe the actual behavior here would be printing “dong” as the shell interpreter is greedy in its evaluation of variables.

the actual behavior here is to echo the literal string "$foobar", because the $ sign is escaped. so no variable expansion will take place at all.

Oh lol. It doesn't show the $ at all on my mobile app till I escaped it
