What is the difference between UNIX and Linux?
Invented at AT&T Bell Labs in 1969, UNIX (the name is a play on the
earlier "Multics" operating system) is a robust, flexible, and
developer-friendly computing environment. Written originally for the
Digital Equipment Corporation (DEC) family of PDP microcomputers, this
most popular of multi-user, general-purpose operating systems has taken
over roles in all areas of computing -- even those once held by
mainframes.

Some twenty-odd years into its history, UNIX began to be eclipsed -- in
some of its roles, anyway -- by Linux. Linux is not UNIX; it is merely
very UNIX-like. For some jobs, you want Linux -- for others, you still
want UNIX. UNIX and Linux play very well together, and well-written
programs are extremely easy to port between the two systems. For more
information about UNIX at IBM, please see some of the following sites.
