Batch editing files with ed

Nice article, good to hear ed is not dead. =)

You could also just add the text after the matching line. A little simpler and more straight forward.

    $ cat > /tmp/ed-script
    /baz
    a
      - elephants
    .
    w
    q
    $ cat /tmp/2
    foo:
      - bar
      - baz
      - bananas
    $ cat /tmp/ed-script | ed /tmp/2
    33
      - baz
    47
    $ cat /tmp/2
    foo:
      - bar
      - baz
      - elephants
      - bananas
    $·

I don’t think matches the spec that the new line has the same number of leading spaces as the surrounding lines

Weird, after rereading the article, it seems like I may have imagined that part.

An older version of the article contained the following:

> I had one extra weird requirement which was that some of the lines were indented with 2 spaces, and some with 4 spaces. The - elephant line needed to have the same indentation as the previous line.

My guess is that the - is replacing something like an org-mode cookie, which could be in a few states that one might want to preserve.
