FreeBSD Desktop – Part 3 – X11 Window System

macOS grep is from FreeBSD, at least as of macOS Mojave (10.14). (Source code for 10.14 might be at https://opensource.apple.com/source/text_cmds/text_cmds-99/g....) Not sure if it was ever GNU grep. Maybe before the big purge in 2011?

IME, most of the basic shell commands are either directly from FreeBSD or a project in the BSD universe. For example tar is from libarchive, a distinct project (see https://github.com/libarchive/libarchive) that DragonflyBSD, FreeBSD, NetBSD, and macOS import and track. (But oddly not OpenBSD, which has evolved the 4.4BSD-Lite implementation.)

According to a 2012 accounting at http://meta.ath0.com/2012/02/05/apples-great-gpl-purge/ (via https://news.ycombinator.com/item?id=3559990), macOS was down to 16 GPL packages in macOS 10.12 from 47 in macOS 10.5.

Yep, it still is. On Big Sur on M1:

    $ grep --version
    grep (BSD grep) 2.5.1-FreeBSD

Yeah, I'm just an idiot. I guess I was just thinking of GNU make.

On the other hand, it looks like (at least on Catalina?) it ships with GNU diffutils, so patch, cmp, diff are all GNU utilities. I'm going to sheepishly pretend like this proves my point somehow :-)
