POSIX
Name
The standards emerged from a project that began in 1984 building on work from related activity in the /usr/group association. Richard Stallman suggested the name POSIX to the IEEE instead of the former IEEE-IX. The committee found it more easily pronounceable and memorable, and thus adopted it.
POSIX
The Portable Operating System Interface (POSIX; IPA: ) 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 shell, and shell commands). Originally derived from commonly-found Unix APIs, shells, and commands (partly because Unix was considered manufacturer-neutral), today many systems conform to the standard – including branded Unix systems, Unix-like systems, and many systems that were historically unrelated to Unix.
POSIX
The standardized user command line and scripting interface were based on the UNIX System V Bourne shell. Many user-level programs, services, and utilities (including awk, echo), ed)) were also standardized, based on UNIX System V versions of them, along with required program-level services (including basic I/O: file, terminal, and network). POSIX also defines a standard threading) library API which is supported by most modern operating systems.
