Answer 1

This works on MacOS Mountain Lion (10.8), Solaris 10 (SunOS 5.10) and RHE Linux (Red Hat Enterprise Linux Server release 5.3, Tikanga)...

$ sed 's/{pattern}/\^J/g' foo.txt > foo2.txt

... where the ^J is done by doing ctrl+v+j. Do mind the \ before the ^J.

PS, I know the sed in RHEL is GNU, the MacOS sed is FreeBSD based, and although I'm not sure about the Solaris sed, I believe this will work pretty much with any sed. YMMV tho'...
