本文介绍了POSIX标准，它是IEEE制定的一系列与Unix兼容的操作系统应用编程接口(API)、Shell及实用程序接口规范。POSIX合规性意味着产品提供了部分或全部POSIX支持，并详细列出了支持的特性。

POSIX (pronounced /ˈpɒzɪks/ POZ-iks) or "P ortable O perating S ystem I nterface [for Unix ]"[1] is the name of a family of related standards specified by the IEEE to define the application programming interface (API), along with shell and utilities interfaces for software compatible with variants of the Unix operating system, although the standard can apply to any operating system.

"POSIX compliance" is a less powerful label, and could merely mean that a product provides partial POSIX support. "POSIX compliance" means that documentation is available that shows which POSIX features are supported and which are not.
