Is that all you want to do, or are you doing something else in your sed
script? I ask because I think it'll be expensive and slow (I haven't
used sed in awhile, but I think you'll end up having to load the entire
file into its memory). The "tr" utility can remove newlines much more
efficiently:

  tr -d '\012' <infile >outfile
