What is this?

A transcript of an editing session using ex.

ex?

If you’ve used Vim or vi, any time you type a command starting with “:”, you’re writing an ex command. ex is the command-line only editor, and vi was originally written to provide better editing on non-dumb terminals.

Why use ex?

This is an exercise in what editing used to be like before the advent of vi.
