HP-UX is a proprietery, industrial strength, extemely reliable version of Unix, I believe based on System V Unix.

Many functions work just like regular Unix. It has a lot of custom add on software specifically designed for it like Service Guard High Availability software.

To be simplistic they started out with Unix years and years ago and evolved it into a wonderful, powerful, reliable Unix based product.

In some areas it complies with standards. In some areas it sets its own standard.

HP-UX is mostly ATT-ish but with odd surprises of its own.

HP-UX has been significantly enhanced with additional features and optional products. The fact that it has an instrumented kernel sets it apart from others in the accuracy and scope of the ability to see its performance with optional GlancePlus and Measureware tools. The system administration tool is also quite user friendly. The virtualization capabilities are also quite good.

Actually, I don't know what "generic Unix" might be. From the references, you'll see that there are two flavors of Unix, BSD and AT&T SysV and these have existed for almost 3 decades, long before there was anything like SCO or Linux or any of the dozens of flavors of Unix.

The user interface for all flavors of Unix is the shell, either Bourne, a POSIX shell like ksh, bash or HP's POSIX shell, possible others. The basic commands (programs) are quite similar except as various standards and manufacturer's definitions create minor differences.

But there is *no* standard at all when it comes to Unix system administration, things like device files, disk mapping, drivers, I/O cards, kernel building, etc. Every flavor will be quite different and that is the challenge in being a multi-platform system administrator.
