Line 2:

There have been two versions of this document.

Its content derives heavily from the [[POSIX]] specification, but the Single UNIX Specification has as of 2001 become more popular among operating system developers than the POSIX specification, largely because the Open Group makes its document available at a much lower price.

As of version 3 the specification contains four sections:

*Base Definitions and Headers<br>(a list of definitions and conventions used in the specifications and a list of [[C]] header files which must be provided by compliant systems)

*System interfaces<br>(a list of available [[C]] system calls which must be provided)

*Shell &amp; Utilities<br>(a list of utilities and a description of the shell, [[sh]])

*Rationale<br>(the explanation behind the standard)
