Talk:Single UNIX Specification

From Wikipedia, the free encyclopedia

Would it be possible for the article to mention the history of the drafting of the standard, including major changes that went into each version (for example, at some point the separate "UNIX environment" (shell) standard was rolled into mainline POSIX)? ---

Is the standard shell for POSIX really "Bourne"?

I do think so -> Please check that at the opengroup's site: Posix 3 aka Unix 3 are freely readable there. But: What does the Term "standard shell" mean? - M-e-leypold 16:29, 16 July 2005 (UTC)

OK, I'm augmenting my previous answer: Yes, sh is the "standard shell. Corresponding entry in Unix03 = Posix3 says "sh - shell, the standard command language interpreter". "Standard" means: (a) This shell must be in a conformant system. (b) It's the only shell that must be in a conformant system. - Regards, M-e-leypold 16:38, 16 July 2005 (UTC)

"Most" Linux vendors don't certify? This should be removed ... has *any* Linux distro *ever* been certified and sold as a UNIX system?

AFAIK: UNIFIX. Do they still certify? -> I don't know. - M-e-leypold 16:29, 16 July 2005 (UTC)

There was a Unix95 mark. Shouldn't that also be mentioned in the article? . M-e-leypold 16:29, 16 July 2005 (UTC).

I have added UNIX93 and UNIX95 --ManoloKosh 15:00, 21 March 2007 (UTC)

[edit] Shell Clarification

The SUS shell, or POSIX shell, includes features the Bourne shell doesn't have, including off the top of my head job control, command line editing, and the $(command) parallel to the `command` construct. It's perhaps unfortunate that it's still called "sh".

In Solaris, /usr/bin/sh will (or did) call the Bourne shell, while /usr/bin/xpg4/sh links to /usr/bin/ksh. PhGustaf (talk) 07:03, 26 November 2007 (UTC)

[edit] Solaris on PPC

I was deeply involved with the Solaris 2.5.1 PowerPC certification. IBM and Motorola, among others, made computers that used PC memory and controller cards, but PowerPC processors. They didn't make them for long. For complicated reasons, TOG required that we get the certification done in 30 days rather than the 180 we were expecting. I do realize that my unsupported memory is not fit material for an encyclopedia. PhGustaf (talk) 20:24, 9 December 2007 (UTC)
