Answer 1

Though I am late to this post, just updating my findings. This answer is only for Mac OS X.

$ sed 's/new/
> /g' m1.json > m2.json
sed: 1: "s/new/
/g": unescaped newline inside substitute pattern

In the above command I tried with Shift+Enter to add new line which didn't work. So this time I tried with "escaping" the "unescaped newline" as told by the error.

$ sed 's/new/\
> /g' m1.json > m2.json 

Worked! (in Mac OS X 10.9.3)
