Contents

How is Unix different from Linux?

Linux is a UNIX Clone.

But if you consider Portable Operating System Interface (POSIX) standards then Linux can be considered as UNIX.

To quote from Official Linux kernel README file: Linux is a Unix clone written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net.

Is Linux a version of Unix?

Linux has been termed as Unix-like, a term which means an operating system that resembles a Unix system. It may not qualify as one or be certified to any particular version of the Single Unix Specification. Linux is also a kernel designed by Torvalds.
