Macos is the UNIX?

why，just beacuse that its the bottom layer uses a small amount of bsd code? In my opinion, macos and Unix are completely different. The directories are long directory structures. For example, /application, /system, /user, /volumes, etc. are completely different from the traditional /bin/ /sbin /etc/ /sys directories. The core uses a mixed kernel of mach and xnu, and is not a traditional monolithic kernel of Unix. The application uses older versions, such as sudo1.8.17, bash3.18. This is updated to sudo1.8.28 and bash5.0 under archlinux. You must also get the app store to install the program. Such an os I think it is more like windows

On the contrary, Linux I feel it more like Unix, keep the simple and stupid Unix style, and even some distributions do not provide gui, just shell mode. The directory follows the Unix traditional directory /bin /boot /etc/ /tmp /var and so on, not innovating alone. The core uses the traditional monolithic kernel written by linus. Installing the software needs to be done under the terminal, although different distributions have different command line styles. Give the user great freedom. In addition to the software you think it is not derived from the original code of at&t, but a cloned version of gnu. I really can't see where it is not Unix. Why do many people call it a class of Unix? What are they thinking about?

Is it only use "car"word call the car, Toyota and Mazuda and Ford do not call the car? ? Is it only use �airplanes�� call the aircraft, Airbus and Boeing are not called airplanes? ? Different motors, different design styles, different appearances. But their principles are the same. In my opinion, as long as the design philosophy of kernel, shell, and user space is followed, having the same directory structure, shell, and underlying c language design can be called Unix.

Therefore, Unix did not disappear, but changed a vest, with gnu/linux, freebsd mode continues to exist.

NAME

       README.macos - Perl under Mac OS (Classic)

SYNOPSIS

       This document briefly describes perl under Mac OS (Classic).  If you are running perl under Mac OS X, you don't want to be here (unless you
       are in the Classic environment under Mac OS X).

       When we say "Mac OS" below, we mean Mac OS 7, 8, and 9, and not Mac OS X.

DESCRIPTION

       The latest perl source itself builds on Mac OS, with some additional pieces. Support for Mac OS is now in the perl core, and MacPerl is
       kept in close sync with regular perl releases.

       To build perl for Mac OS (as an MPW tool), you will need the addition of the macos subdirectory, distributed separately.  It includes extra
       source files, config files, and make files.  It also includes extra Mac-specific modules.

       To build the MacPerl application, you will also need the macperl directory, which includes the source files for creating the application
       itself.

       All of this is available from the development site, via HTTP (in the MacPerl Installer, which includes all the source and binaries) and
       anonymous CVS.

	       http://dev.macperl.org/

       The source is also in the main perl repository in the macperl branch (the 5.6 source is in the maint-5.6/macperl branch).

       You will also need compilers and libraries, all of them freely available.  These are linked to from the SourceForge site. Go that site for
       all things having to do with MacPerl development.

       MacPerl 5.6.1 and later are supported on Mac OS 8.1 and later, for 68040 and PowerPC architectures.  The MPW tool may be used on Mac OS
       7.5.5 and 68030 computers.

       MacPerl 5.2.0r4 is also available, on the CPAN and on SourceForge.  It is based on perl 5.004, and works with Mac OS 7.5.5 and 68030 com-
       puters.
