Introduction
It’s been almost eight years since I first updatedAdvanced Programming in the UNIX
Environment,and already so much has changed.
•Beforethe second edition was published, The Open Group created a 2004
edition of the Single UNIX Specification, folding in the changes from two sets of
corrigenda. In 2008, The Open Group created a new version of the Single UNIX
Specification, updating the base definitions, adding new interfaces, and
removing obsolete ones. This was called the 2008 version of POSIX.1, which
included version 7 of the Base Specification and was published in 2009. In 2010,
this was bundled with an updated curses interface and reissued as version 4 of
the Single UNIX Specification.
•Versions 10.5, 10.6, and 10.8 of the Mac OS X operating system, running on Intel
processors, have been certified to be UNIX® systems by The Open Group.
•Apple Computer discontinued development of Mac OS X for the PowerPC
platform. From Release 10.6 (Snow Leopard) onward, new operating system
versions arereleased for the x86 platform only.
•The Solaris operating system was released in open source form to try to compete
with the popularity of the open source model followed by FreeBSD, Linux, and
Mac OS X. After Oracle Corporation bought Sun Microsystems in 2010, it
discontinued the development of OpenSolaris. Instead, the Solaris community
formed the Illumos project to continue open source development based on
OpenSolaris. For moreinformation, seehttp://www.illumos.org.xxi
