Determining What Version of the HP-UX Operating System is Running
To determine what version of operating system you are running and on which platform,
use the uname command with the -a option:
uname -a
HP-UX tavi B.11.31 A 9000/800 1920004321 two-user license
In the example above, the system returned the following information:
HP-UX
Operating system name
tavi
System name
B.11.31
Operating system release identifier
A
Operating system version identifier
9000/800
Machine and model numbers
1290005321
Machine identification number
two-user license
Operating system license level
For more information about uname, see uname(1).
NOTE: The system release identifier B.11.31 corresponds with HP-UX 11i Version 3.
Checking the System’s Run Level
To find out what run level the system is in (for example if you want to check that you
are in single-user mode) enter:
who -r
The run level is the number in the third field from the right.
For example, this output
run-level 4 Apr 23 16:37 4 0 S
means that the system is in run-level 4.
