need help in understanding HP-UX kernel info 1

[whn]

I am developing a tool which is intended to support all unix platforms including HP-UX. And for HP-UX, my tool is supposed to behave a little differently on 11i v1.0, 11i v2.0 & 11i v3.0. However, when I use 'uname -a', I don't know how to tell which piece of info means 11i v1.0, v2.0, or v3.0.

# uname -a
HP-UX tbird B.11.23 U 9000/800 98684004 unlimited-user license
# uname -r
B.11.23

I googled some info and realize that 11.23 is probably 11i v2.0. but I could not find what the rule is for mapping the output of 'uname -r' to 11i vx.0. And I don't understand what 'B' means of the output of 'uname -r'.

Any help or guidance is highly appreciated!

I'm not sure what the B means, but this should answer the other questions.

Thank you, Annililannic!

How come I did not google that page out?

so, I guess there is no version numbers in between 11.11 & 11.23 and between 11.23 & 11.31? Why would HP do this? To confuse us?

Thanks again!

You only need to look at the history of Unix to see that it is traditional for Unix vendors to try and confuse us! Take SunOS 4.1.4 -> Solaris 2.x (a.k.a SunOS 5.x) -> Solaris 7 for example. The Wikipedia HP-UX article is perhaps a better reference as it includes explanations of the differences. You'll see that there are other revisions in between, but they are not official releases that are likely to be widely deployed.
