+ | Prepared on January 17, 1984, the /usr/group standard is an early UNIX standard proposed by the /usr/group international network of UNIX users. | ||
+ | |||
+ | From the abstract: | ||
+ | |||
+ | This document describes a Standard for computer operating systems that are functionally compatible with the UNIX operating system developed by AT&T Bell Laboratories. | ||
+ | |||
+ | This document is intended to be used by both application and system vendors to assist with the development of computer software which is portable across a large number and wide variety of computer systems. | ||

+ | The System V Interface Definition is a series of publications describing the minimum required user and application interface expected of UNIX systems published as System V compatible. | ||
+ | |||
+ | As the SVID was more particular to UNIX System V, it contains many components not found in the POSIX standard. | ||
+ | |||
+ | From the introduction of the Fourth Edition: | ||
+ | |||
+ | The System V Interface Definition (SVID) is intended for use by anyone who must understand the operating system components that are consistent across all System V environments. | ||

+ | IEEE 1003.1, otherwise known as the POSIX standard, is published by the IEEE and is the current basis of the Single UNIX Specification as maintained and enforced by The Open Group. | ||
+ | |||
+ | While IEEE 1003.1 itself merely defines the C language interfaces for system services, additional 1003-family standards exist, such as 1003.2, defining the user-level commands available on UNIX systems. | ||
+ | |||
+ | From the foreword of IEEE 1003.1-1988: | ||
+ | |||
+ | The purpose of this standard is to define a standard operating system interface and environment based on the UNIX Operating System documentation to support application portability at the source level. | ||
+ | |||
+ | The foreword goes on to describe the derivation of this standard: | ||
+ | |||
+ | The various interface facilities described herein are based on the 1984 /usr/group Standard derived and published by the /usr/group Standards Committee, Santa Clara, California. | ||

+ | Above is Go Solo, an informative work published by X/Open in 1995 with the initial version of the Single UNIX Specification included on a CD-ROM. | ||
+ | |||
+ | Go Solo is designed as an aid to understanding the Single UNIX Specification as well as a means of delivering 2,700 pages of X/Open Specifications in a convenient and easily accessible media, namely on CD-ROM with an SGML-based browser. |
