Unix was selected as the basis for a standard system interface partly because it was 'manufacturer-neutral'. The committee found it more easily pronounceable and memorable, and thus adopted it. Richard Stallman suggested the name POSIX to the IEEE instead of former IEEE-IX. The standards emerged from a project that began in 1984 building on work from related activity in the /usr/group association. The family of POSIX standards is formally designated as IEEE 1003 and the ISO/IEC standard number is ISO/ IEC 9945. Originally, the name 'POSIX' referred to IEEE Std 1003.1-1988, released in 1988. POSIX is intended to be used by both application and system developers. POSIX defines both the system and user-level application programming interfaces (APIs), along with command line shells and utility interfaces, for software compatibility (portability) with variants of Unix and other operating systems.

The Portable Operating System Interface ( POSIX, with pos pronounced as in positive, not as in pose ) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems.
