Once was and still is too.  The GNU ed is available.

When I was at university I wrote thousands of lines of code using qed
(a precurser to ed on the old Honeywell GCOS system) and paper
terminals over acoustic coupled modems.  If nothing else it will teach
you how to use regular expressions at a very deep level!  Editors like
ed are actually very efficient if you know how to use them.

Agreed.  Very painful.  From first hand experience.

Here is a funny modern day ed story.  Well it is funny to me anyway.
At one time I and another buddy George were helping someone with a
problem he was working on.  It came time to edit a file.  I told him
"Edit the file by your favorite method."  I usually avoid saying
"emacs the file" or "vi(m) the file".  Everyone prefers a different
editor.  Use whatever editor you normally use.

For whatever reason this person typed in "ed thefilename" and then
looked up at me.  I knew it was a typing mistake.  I should have said,
"Do you really mean to use ed on that file?"  But instead I looked at
George.  George looked at me.  We had both used ed a lot in the past.
Out of a sense of perversity we both said together, "Okay.  Let's do
it!"  And then we began to give him 'ed' editing instructions for the
file.  It was a short file so "1,$p" to see it all and then
"3s/foo/bar/p", "g/baz/s//foo/" and so forth to make the needed
changes.  Editing went pretty quick.  "wq" writes the file and quits.

Afterward this person asked George and myself why had we used ed?  I
said that we didn't have anything to do with that choice.  He was
driving the keyboard.  The choice of editor was his!  I am still
chuckling about it.  But I guess this is one of those where you had to
be there...

I still prefer emacs however.
