> pip just makes more sense than copy.

PIP was a stock tool on DEC OS-8 and other OSes of which CP/M was basically a cheapo cut-down Intel version.

It also has an “ed” that will make you miss UNIX’s “ed”. I’ve used it to write programs and it is not fun!

Wasn't that abbreviation from "pipe"? As in - this is a pipe that you can use to connect terminal to a file, file to a printer... and yes, file to a file (that's cp/copy).
