The Portable Operating System Interface (POSIX; IPA: /ˈpɒz.ɪks/[1]) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems.[1] 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.[1][2] POSIX is also a trademark of the IEEE.[1] POSIX is intended to be used by both application and system developers.[3]
