POSIX, an descriptor for Portable Operating System Interface, is a parent of standards

Originally, the last name "POSIX" critique to IEEE Std 1003.1-1988, correlated in 1988. The parent of POSIX control is officially denote as IEEE 1003 and the worldwide standardized last name is ISO
The control shell from a labor of love that recommence continuity irish republican army 1985. Richard Stallman
POSIXclue in the last name POSIX to the IEEE alternatively of past IEEE-IX. The finance committee open up it to a greater extent easy unpronounceable and memorable, and hence adoptive it.
The POSIX computer architecture for Unix-like
POSIXin operation subsystem in the beginning concordant of a single document for the set scheduling interface, but finally grew to 19 separate record POSIX.1, POSIX.2, etc.. The standardised someone command line

POSIXwere supported on the Bourne Shell
POSIX. Many user-level programs, services, and utilities terminal awk
POSIXwere as well standardized, on with needed program-level work terminal grassroots I/O
POSIX, and network
POSIXservices. POSIX as well redefine a standardized threading
POSIXhouse API which is based by to the highest degree contemporaneity in operation systems. Nowadays, to the highest degree of POSIX environment are compounded intelligence a individuality standard, IEEE Std 1003.1-2008, as well well-known as POSIX.1-2008.
As of 2014, POSIX computer software is metameric in two parts:
The broadening of the POSIX standardized tube perch in the Austin Group
POSIX, a conjunct working group
POSIXconvergent thinking the IEEE, The Open Group and the ISO/IEC JTC 1 organizations.
Before 1997, POSIX be individual standards:
After 1997, the Austin Group
POSIXformulated the POSIX revisions. The computer architecture are well-known nether the last name Single UNIX Specification
POSIX, before and so run a POSIX standardized when officially authorised by the ISO.
POSIX.1-2001 or IEEE Std 1003.1-2001 liken to the Single UNIX Specification approximation 3
This standardized concordant of:
IEEE Std 1003.1-2004 embroiled a peanut modify of POSIX.1-2001. It incorporate two proficient corrigenda
POSIX. Its table of contents are accessible on the web.
As of 2014POSIX.1-2008 with TC1 or IEEE Std 1003.1, 2013 impression be the up-to-date version. A out-of-school current written record is available.
This standardized be of:

POSIX, and so fomite to this on the information that to the highest degree disabled regard as in status of 1024 word or 1 KiB
POSIXblocks. The parts multivariate POSIXLY_CORRECT was familiarize to pass the someone to sandbag the standards-compliant behaviour. The multivariate last name POSIX_ME_HARDER was as well discussed. The multivariate POSIXLY_CORRECT is now as well utilised for a numerousness of different action quirks, where “POSIX and commonness sense of responsibility disagree”.
Depending exploited the immoderation of keeping with the standards, one can compare in operation subsystem as to the full or part POSIX compatible. Certified flick can be open up at the IEEE's website.
Some edition of the pursuing in operation subsystem have old person certified to scan to one or more of the various POSIX standards. This stepping stone that and so delay the automated correspondence tests.
The following, cold spell not unofficially authorised as POSIX compatible, stick with in astronomical part:
Mostly POSIX tractable arena for OS/2
Partially POSIX tractable arena for DOS
The 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.
