Who's Connected to CMS using Supervisor? (R17 and maybe below)

If you close the program now that'll be the end of it. I will not look for you, I will not pursue you, but if you don't, I will look for you, I will find you and I will boot you.

This is exactly the same content as the R18 version of this post but for CMS R17.

The linux w command will tell you who's currently logged in.

w - display information about currently logged-in users

Run it and you'll see something like this:

$ w
 11:12am  up 532 day(s),  1:22,  3 users,  load average: 0.22, 0.24, 0.25
User     tty           login@  idle   JCPU   PCPU  what
cmsuser1 pts/2         4:58am           14     14  chip
cmsuser2 pts/3         4:59am           18     18  chip
cmsuser3 pts/4         6:35am           51     51  chip
cms      pts/8        10:07am                      w

Those chip entries are CMS Supervisor users. If you want to see just those entries, do the following:

$ w | grep chip
cmsuser1 pts/2         4:58am           14     14  chip
cmsuser2 pts/3         4:59am           18     18  chip
cmsuser3 pts/4         6:35am           51     51  chip

Finally, if you just want to see how many people are logged in with Supervisor, use wc to get a line count:

$ w | grep chip | wc -l
