Question

how to replace a match with multiple lines in emacs.

Example:- replacing "Dog" with barking animal

as shown below

The Dog 

with

The Barking
animal

I tried \n in the command replace-regexp, for which emacs throws error saying Invalid use of `\' in replacement text

Answer 1

As documented in this article, the answer is to use C-qC-j to enter your newline if you're using M-x replace-string

So for you:

M-x replace-string RET Dog RET Barking C-qC-j animal RET
