<< WHY THEN HARDY OR ROOT IS SPARED IN W ??? >>
============================================
As you can see, the user locum logged in at ttyp7,8, d & e are not
shown in finger. I know the user locum is not really logged in, and
though the processes shown by w exist ( in ps) !!!.
But why is the discrepancy ? user locum has those background processes
also root or some other users (hardy). But they are not listed in who/w/finger
only locum is listed.
Please clarify. Thanks in advance.

All of the above names (prabal, locum , hardy and layne are valid
