All Unix, Linux and other Unix-like operating systems are families of computer operating systems derived from the original Unix System from AT&T Bell Laboratories. Today, the largest Unix descendent directly certified as UNIX is macOS by Apple. The original commercial Unix derivatives included HP-UX, AIX and SunOS, to name a few.
