 In my opinion, unix is a description of the function of an operating system. I even say that unix is an Application Programmer'​s Interface (API). Any operating system which implements the unix API is a unix; it's an implementation of unix. Gnu/Linux is a unix.3.1 Gnu/Linux is often called Linux, but strictly speaking, Linux is a unix kernel, but not a whole unix operating system. There are many other implementations of unix. I can name original BSD, OpenBSD, FreeBSD, NetBSD, HP/UX, AIX, Minix, Apple Macintosh OS 10, NeXT STEP, QNX, & Lynx. There are probably others. In my opinion, unix is a description of the function of an operating system. I even say that unix is an Application Programmer'​s Interface (API).

-Now for some legal bullshit. ​``UNIX'' ​is a trademark of The Open Group. From what I can infer from their web site about their opinions of what unix is, they would agree with me that it's a description of the function of a family of operating systems, but they would also add ``that we have certified to be UNIX''​. So legally, it's not a UNIX unless The Open Group certifies it as a UNIX. So a lot of those operating systems I listed as unices are not UNIXes. It's a thoroughly sad case of legalities getting in the way of simplicity & sanity.+Now for some legal bullshit. ​<​nowiki>"</​nowiki>​UNIX<​nowiki>"</​nowiki> ​is a trademark of The Open Group.

 Anyway, I say that if an operating system behaves like unix, then it's a unix, though not necessarily a UNIX$^{(tm)}$. Anyway, I say that if an operating system behaves like unix, then it's a unix, though not necessarily a UNIX$^{(tm)}$.
