== The remaining Unixes (and their manpages)

Because I was just looking this up [[the other day
../programming/ModernSocketsListening]], here is my list of the
remaining Unixes that are still alive and where to find their manpages
online.  Of these, the ones that I think matter significantly any more
*as Unixes* are Linux, FreeBSD, OpenBSD, Solaris (maybe not for much
longer) and perhaps MacOS X (depending on what you're doing).

The list:

* Linux ([[yes, really ../linux/LinuxIsAUnix]]) \\
  It's a bit hard to find current Linux manpages online, although there
  are lots of places with somewhat out of date ones available. [[The
  man-pages project http://www.kernel.org/doc/man-pages/]] is
  probably the authoritative reference for system calls and glibc
  stuff; for manpages in general, see [[tldp.org's manpages section
  http://tldp.org/manpages/man.html]] and its collection of links,
  especially [[this searchable version http://manpages.courier-mta.org/]].

  (There's also [[man.he.net http://man.he.net/]].)

* the *BSDs: FreeBSD, NetBSD, OpenBSD, and Dragonfly BSD. \\
  All of them have manpages easily available through the documentation
  section of their own websites; 
  [[FreeBSD manpages http://www.freebsd.org/cgi/man.cgi]],
  [[NetBSD manpages http://www.netbsd.org/docs/#documentation-manual-pages]],
  [[OpenBSD manpages http://www.openbsd.org/cgi-bin/man.cgi]], and
  [[DragonflyBSD manpages http://leaf.dragonflybsd.org/cgi/web-man]].

* Sun's Solaris, oops, I mean Oracle's Solaris \\
  At least until Oracle reorganizes everything, the Solaris 10 manpages
  are part of the [[Solaris 10 documentation collection
  http://docs.sun.com/app/docs/prod/solaris.10]], and can be found online
  [[here http://docs.sun.com/app/docs/coll/40.10?l=en]].

* Apple's MacOS X \\
  Online manpages are currently [[here
  http://developer.apple.com/mac/library/documentation/Darwin/Reference/ManPages/index.html]],
  I would assume for the current version only.

* IBM's AIX \\
  The [[manpages for AIX 6.1
  http://publib.boulder.ibm.com/infocenter/aix/v6r1/index.jsp]]
  really need JavaScript, and a few previous versions seem to only be
  available in PDFs if you know the right 10 Mb PDF that you want.

* HP's HP-UX and perhaps [[Tru64 http://en.wikipedia.org/wiki/Tru64]] \\
  HP seems to have not made up their mind about where their manpages
  are; online manpages for all sorts of HP-UX releases are [[here
  http://docs.hp.com/en/hpuxman_pages.html]] or less usefully [[here
  http://www.hp.com/go/hpux-core-docs]] in PDF form. There's also
  Tru64 stuff [[here http://www.hp.com/go/tru64unix-docs]], all in
  PDF.

Sadly departed is [[SGI's IRIX http://en.wikipedia.org/wiki/IRIX]], among
many other Unixes.

For a general reference on portability, see the [[Single Unix
Specification http://www.opengroup.org/onlinepubs/9699919799/]]
(background [[here http://en.wikipedia.org/wiki/Single_UNIX_Specification]]).

(By the way, my criteria for whether an online Linux manpage collection
is sufficiently up to date is whether its _ipv6_ manpage mentions
((IPV6_V6ONLY)), since this is what I was looking up the other day.)
