The Portable Operating System Interface POSIX1 is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. POSIX defines the application programming interface API, along with command line shells and utility interfaces, for software compatibility with variants of Unix and other operating systems. Originally, the name POSIX referred to IEEE Std 1. The family of POSIX standards is formally designated as IEEE 1. ISOIEC 9. 94. 5. The standards emerged from a project that began circa 1. Richard Stallman suggested the name POSIX to the IEEE instead of former IEEE IX. The committee found it more easily pronounceable and memorable, and thus adopted it. OvervieweditUnix was selected as the basis for a standard system interface partly because it was manufacturer neutral. However, several major versions of Unix existedso there was a need to develop a common denominator system. The POSIX specifications for Unix like operating systems originally consisted of a single document for the core programming interface, but eventually grew to 1. POSIX. 1, POSIX. 2, etc. The standardized user command line and scripting interface were based on the UNIX System V shell. Many user level programs, services, and utilities including awk, echo, ed were also standardized, along with required program level services including basic IO file, terminal, and network. POSIX also defines a standard threading library API which is supported by most modern operating systems. In 2. 00. 8, most parts of POSIX were combined into a single standard IEEE Std 1. POSIX. 1 2. 00. 8. As of 2. 01. 4update, POSIX documentation is divided in two parts POSIX. Edition POSIX Base Definitions, System Interfaces, and Commands and Utilities which include POSIX.

This is POSIX 1. 00. Technical Corrigendum 1. POSIX Conformance Testing A test suite for POSIX accompanies the standard VSX PCTS or the VSX POSIX Conformance Test Suite. The development of the POSIX standard takes place in the Austin Group a joint working group linking the IEEE, The Open Group and the ISOIEC JTC 1 organizations. VersionseditParts before 1. Before 1. 99. 7, POSIX comprised several standards Versions after 1. After 1. 99. 7, the Austin Group developed the POSIX revisions. The specifications are known under the name Single UNIX Specification, before they become a POSIX standard when formally approved by the ISO. POSIX. 1 2. 00. 1editPOSIX. IEEE Std 1. 00. 3.

When Richard Stallman and the GNU team were implementing POSIX for the GNU operating system, they objected to this on the grounds that most people think in terms of 1. Ki. B blocks. The environment variable POSIXLYCORRECT was introduced to allow the user to force the standards compliant behaviour. This variable is now also used for a number of other behaviour quirks, where POSIX and common sense disagree. POSIX oriented operating systemseditDepending upon the degree of compliance with the standards, one can classify operating systems as fully or partly POSIX compatible. Certified products can be found at the IEEEs website. POSIX certifiededitSome versions of the following operating systems have been certified to conform to one or more of the various POSIX standards. This means that they passed the automated conformance tests. Mostly POSIX complianteditThis section needs expansion. You can help by adding to it. January 2. The following, while not officially certified as POSIX compatible, comply in large part POSIX for Microsoft WindowseditCygwin provides a largely POSIX compliant development and run time environment for Microsoft Windows. Min. GW, a fork of Cygwin, provides a less POSIX compliant development environment and supports compatible C programmed applications via Msvcrt, Microsofts old Visual C runtime library. Microsoft POSIX subsystem, an optional Windows subsystem included in Windows NT based operating systems up to Windows 2. POSIX 1 as it stood in 1. Interix, originally Open. NT by Softway Systems, Inc., is an upgrade and replacement for Microsoft POSIX subsystem that was purchased by Microsoft in 1. It was initially marketed as a stand alone add on product and then later included it as a component in Windows Services for UNIX SFU and finally incorporated it as a component in Windows Server 2. R2 and later Windows OS releases under the name Subsystem for UNIX based Applications SUA later made deprecated in 2. Windows 83. 1 and dropped in 2. R2, 8. 1. It enables full POSIX compliance for certain Microsoft Windows products. Windows Subsystem for Linux is a compatibility layer for running Linux binary executables natively on Windows 1. Ubuntu image, acting as an upgrade and replacement for Windows Services for UNIX. It was released in beta in April 2. UWIN from AT T Research implements a POSIX layer on top of the Win. APIs. MKS Toolkit, originally created for MS DOS, is a software package produced and maintained by MKS Inc. Unix like environment for scripting, connectivity and porting Unix and Linux software to both 3. Microsoft Windows systems. A subset of it was included in the first release of Windows Services for UNIX SFU in 1. Windows C Runtime Library and Windows Sockets API implement commonly used POSIX API functions for file, time, environment, and socket access,3. POSIX compliant implementations. POSIX for OS2editMostly POSIX compliant environments for OS2 POSIX for DOSeditPartially POSIX compliant environments for DOS include emxgcc largely POSIX compliant. DJGPP partially POSIX compliant. DR DOS multitasking core via EMM3. MULTI a POSIX threads frontend API extension is available. Compliant via compatibility featureeditThe following are not officially certified as POSIX compatible, but they conform in large part to the standards by implementing POSIX support via some sort of compatibility feature usually translation libraries, or a layer atop the kernel. Without these features, they are usually noncompliant. See alsoeditReferenceseditPOSIX. FAQ. The Open Group. October 2. 01. 1. POSIX 1. FAQ Version 1. Cap Cost Program. February 2. 00. 6.
