POSIX: Standards, Conformance & Overview

The Portable Operating System Interface (POSIX; IPA: /ˈpɒz.ɪks/) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. In order to define a level of compatibility, POSIX specifies many aspects of functionality that can be classified as application programming interface (API), command-line…
