How do I use a new-line replacement in a BSD sed?

Question

Greetings, how do I perform the following in BSD sed?

sed 's/ /\n/g' 

From the man-page it states that \n will be treated literally within a replacement string, how do I avoid this behavior? Is there an alternate?

I'm using Mac OS Snow Leopard, I may install fink to get GNU sed.

Answer 1

In a shell, you can do:

    sed 's/ /\ /g' 

hitting the enter key after the backslash to insert a newline.

Answer 2

Another way:

sed -e 's/ /\'$'\n/g'
