> However, this is not due to old tools. Those differences are just how up current (up to date) BSD commands work. They are just a different unix lineage than Linux. What up-to-date BSD are you referring to? The commands on different forks of BSD like FreeBSD vs OpenBSD are not the same. And quickly looking at the man pages of latest FreeBSD vs MacOS versions of ls, for example - they are not the same. > These days, even if Apple decided it's worth the technical fallout of switching from BSD command line tools to GNU, they wouldn't do it for the same legal reason as what keeps Bash at 3.2: The current GNU tools are licensed as GPLv3. What actually prevents them from including GPLv3 software?
