That might actually have been a better way to do it.
The reason your first try didn't work because "or" wasn't really what you wanted. You flipped the logic with the !=, which changes the picture a bit -- a string can't possibly be equal 12 and 24 at the same time! One or the other, or both, will always be false, flipping that makes one or the other always true; and or-ing that produces a statement which is always true no matter what.
To do it with ||:
I think the -z is superfluous, then, since a null string will never equal 12 or 24.

I'm trying to find out how many logical partitions our AIX box has. I'm running the command: topas -C
and nothing is showing up. Is it safe to say that there is only one LPAR, which is what AIX is installed on?
