That's true, Robert; I had forgotten that the IND command does show the
last IPL statement....of course, if some knuckle head had installed
Linux on a virtual DASD at address 190, then that could pose a
problem....:-)

If IPL device is sufficient, then it is not necessary to install TRACK.
The IPL device or system is in the "CP IND USER userid" response, so a
PIPE can be used to count all the userids IPL'ed by device, excluding
the IPL 190 userids.

Hi, Sunny.
Some sites have guest naming standards (Linux guests are named LIN....
or LS....., etc.) that would allow you to very simply see which guests
were running Linux, as opposed to CMS or GCS. If your site doesn't have
such a standard, then I'm afraid you're going to have to do this the
hard way.
I would download and install the TRACK z/VM utility; for each guest on
the system, it can tell you what the IPL statement was, and if all of
your Linux guest were IPLed off of a known DASD address, that would tell
you which ones are indeed running Linux. To verify that the guest is a
Linux one, TRACK can also display the kernel parm line, which is stored
at a fixed location (x'1000'?) in the guest.
This isn't too difficult to do for a handful of guests, but if you have
a lot to query, you might want to consider automating this task via some
Rexx TRACK macros.

the cp commands:Q N is not very suitable for this question.
What is the better way?
