From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

no, it's not
I think this is a Ship of Theseus thing here that we're going to argue about because at what point is it just UNIX-like and not UNIX?
UNIX-like is definitely a descriptor currently used for Linux.
Even the Wikipedia entry starts that way.
It's Unix if you pay to have it certified (assuming it's compatible to begin with). That's basically it.
Yes, but it's not Unix. That's literally part of GNU/Linux' name.
Mac OS is more Unix than Linux.
