One edits files in place, interactively. The other edits streams i.e.batch processing.

You want sed -i -f -

ed is also the precursor of sed, and of some other dozen of commands.

Yes ed begat sed, but sed works differently. It didn't replace ed. It did a different job.

Ed loads the file into a buffer which you edit in a random access fashion and then save. Sed collects a list of commands and then streams the file line by line, executing the commands as they match lines. In your example nothing happens until you've entered the whole editing script.
