Ask HN: Ergonomy of line-oriented programs (like ed)

I am currently asking myself besides `ed`[1] what are the CLI/line-oriented program existing and their ergonomic usage?

I know that may see weird at the time of extra big screens to look at teletype oriented programs but playing around with `ed` and also the `cmd` module of python's standard library [2] made me look around. I remembered turtle/Logo [3][4] also :)

Any other example to share? How different of a REPL those programs were at the end? A better name would be : Command Line-oriented interpreters?
