An operating system is said to be Unix-based or Unix-like if it’s designed to function and behave similar to the Unix operating system. Examples of proprietary Unix-like operating systems include AIX, HP-UX, Solaris, and Tru64.
What is the difference between Unix and Unix-like operating system?
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, while not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell.
