Format:

locate -switch -switch ... logname logname logname ...

Locate will type the names of the users being  located  with  the
tty  name  they are sitting at, or [not logged in] if such is the
case.

Switches:

-all            list all logged in users
-count          include total logged in user count
-full           include full names of located users
-location       include a statement vaguely related to the users
                current location
-mnemonic       include user course affiliation
-quick          compress listing as much as possible
-time           include login time
-whole          list all information for located users

     only the unique minimal abbreviation of  a  switch  need  be
given.   (with the current set of switches, the minimal abbrevia-
tion is the first character.)

"locate -all -quick -count" is equivalent to "who".
