ed goes back at least as far as the Bell Labs 6th Edition (PDP-11), where it was the only editor in the distribution. ex and vi (and termcap, without which there would be no vi) were written later, at UC Berkeley. > If you had a nice video terminal then you used vi.

More like, ed was the "original" Unix editor; ex and vi presumably were inspired, at least in part, by a desire to improve on ed's limitations. I doubt I'm the only one who muttered about the bother of horsing around with ed, back when there was nothing else. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
