I guess my confusion comes from the fact that if you background ed,
you'll need to bring it back into the foreground to interact with it.
I suppose this makes sense if you're occasionally modifying a file
that's growing, and you want to keep your place as you go. From a
script, though, I'd generally use sed (or more likely perl).

I haven't used it much, but "expect" is designed to work with
interactive commands through scripts. You might also try telling ed
that stdin is coming from some other filehandle than the keyboard, say
a file descriptor, a pipe, a regular file, or a FIFO (named pipe).
