That was the first thing I tried and sed gave me an error: sed: -e expression #1, char 18: unknown option to `s' I just went back and tried it again and it worked, so I have no idea what I did the first time that made it not work.
You can run into that sort of problem if your pattern to replace contains any forward slashes (/) in it. If you need to such an expansion, you probably want to do it in two passes, first doing a / to \/ substitution on your replacement strings, then inserting them into your final expression:
pata=`echo $1 | sed 's,/,\/,'` patb=`echo $2 | sed 's,/,\/,'` sed -e "s/PATTERN1/$pata/" -e "s/PATTERN2/$patb/" < input > output me
