Hm, my suggestion was wrong... sed is a bit cryptic to learn from the
manual page. The manual can be used as a reference, if you alread know
So, ba is:
branch to the a label
My points are:
If you want to learn sed, you have to invest some time.
If you want to ask for an one-liner that does what you want,
that's fine too.
sed isn't only s/foo/bar/. There is a dc(1) clone in sed,
which is at least an amazing accomplishment for sed. You
might want (or not) to learn more things about it.

I think this version of sed is different too, since it's part
of BSD since 4.4BSD. It may be compatible with the older BSD
one. The in-place replacement is a non-standard extension which
both BSD and GNU sed share.
