using sed to sub a new line

[mbrohm]

I am trying to change a file to add information at certain points, but I also need to a new line like add:

test = true
metadata = false

so i did a sed 's/end/^M test = true ^M metadata = false/' tmp > tmp2

but in tmp2 i see end^M test = true^M metadata = false.

I have also tried \n instead of ^M but i get n in the file and I have tried \\n which gives me \n in the file. Any ideas of what I am doing wrong??

Thanks

append lines after matching pattern:
/pattern/ahkjhkjhkjhkjhkjhkh
opipoppipoippipoip
lkjlkjlkjljlkjl
<here-is-an-empty-line>

insert lines before matching pattern:
/pattern/ihkjhkjhkjhkjhkjhkh
opipoppipoippipoip
lkjlkjlkjljlkjl
<here-is-an-empty-line>
