Be aware if you are going to delve into history that grep is the source of much confusion, in part because exactly which program was grep on some systems has changed over the years. On FreeBSD, for example, some years ago grep was the GNU tool and the BSD tool was named "bsdgrep". They would both identify as the same version number.

> On FreeBSD, for example, some years ago grep was the GNU tool and the BSD tool was named "bsdgrep". They would both identify as the same version number. Neither of these statements are true. grep on FreeBSD is still GNU grep, and it has a distinct version text from bsdgrep: $ grep -V grep (GNU grep) 2.5.1-FreeBSD Copyright 1988, 1992-1999, 2000, 2001 Free Software Foundation, Inc.

    MacOS isn't FreeBSD. They're free to do whatever they want with the BSD-licensed software. Your comments made claims about FreeBSD that weren't factual. I would also emphasize that: strcmp("bsdgrep (BSD grep) 2.5.1-FreeBSD", "grep (GNU grep) 2.5.1-FreeBSD") != 0 Also, I'm personally in contact with Kyle Evans and am familiar with the general interest in making bsdgrep grep. But I also know that it hasn't happened yet.
