- `POSIX is the term for a suite of applications program
interface standards to provide for the portability of source code
applications where operating systems services are required. POSIX is
based on the UNIX (Registered trademark administrated by the Open
Group) Operating System, and is the basis for the Single UNIX
Specification from The Open Group.' [IEEE PASC (Portable
Application Standards Committee)]
- This is currently (2001-06-20) undergoing revision by the
Austin
Group
- The POSIX standard is
- `IEEE Std 1003.1 Standard for Information technology -- Portable
Operating Systems Interface (POSIX) -- Part 1: System Interface [C
language binding]', which is identical to `ISO/IEC JTC1 IS 9945-1
Standard for Information technology -- Portable Operating Systems
Interface (POSIX) -- Part 1: System Interface [C language binding]'
- `IEEE Std 1003.2 Standard for Information technology -- Portable
Operating Systems Interface (POSIX) -- Part 2: Shell & Utilities',
which is identical to `ISO/IEC JTC1 IS 9945-2 Standard for
Information technology -- Portable Operating Systems Interface (POSIX)
-- Part 2: Shell & Utilities'.
...and these cost money (lots) to buy on paper. - Single
Unix specification, from the Open Group (other
publications). My understanding from the PASC document above is
that Single Unix is broader than POSIX, and covers more of the
environment (bit vague, here). It feeds into the POSIX/ISO
standardisation process, but is not a formal standard itself. Single
Unix does, however, have the great advantage of being available
online.
- The link with The Unix
System is, I fear, rather obscure to me, but it appears that
the latter is the public face of the Open Group's
labours.
