The who command

When used with the -lH option, the who command examines the /var/adm/utmp file and lists running port monitors. When used with a -u option, it lists all users who are currently logged in. See the who(1) manual page for complete information on its use.

Listing running port monitors

To list all RUNNING port monitors, enter:

who -lH

For example, when ttymon in express mode is monitoring a line, the name field is ``LOGIN'' as shown for term/03 in the following example.

   #who -lH
   NAME      LINE         TIME          IDLE  PID   COMMENTS
   LOGIN     term/03      Jun 17 12:49  old   6744  
   ttymon1   .            Jun 17 12:50  old   8234
   ttymon3   .            Jun 17 12:50  old   8235

Listing all logged-in users

To list all users who are currently logged, enter:

who -u

The following is example output:

   root       console      Jun 17 13:07   .      8303
   john       tp/15        Jun 17 13:13   0:01   8353
