WHO(1)                  COMMAND REFERENCE                  WHO(1)



NAME
     who, users, u - who's logged in on local machines or on the
     current host system

SYNOPSIS
     who [ -q ] [ -s ] [ -H ] [ -T ] [ -N ] [who-filename]
     who [ am I ]
     users
     u

DESCRIPTION
     Without an argument, who lists the login name, terminal
     name, login time, and idle time for each current UTek user.
     The commands users and u are short forms of who that lists
     only the names (equivalent to who -q).

     Without an argument, who examines the /etc/utmp file to
     obtain its information.  If a file is given, that file is
     examined.  Typically the given file will be /usr/adm/wtmp,
     which contains a record of all the logins, logouts, and
     crashes since the creation of the wtmp file.  Each login is
     listed with the user name, terminal name (with /dev/
     suppressed), and date and time.  When an argument is given,
     logouts produce a similar line without a user name.  Reboots
     produce a line with x in the place of the device name and a
     fossil time indicative of when the system went down.

     With the arguments, am I (or am i) who tells who you are
     logged in as.

     The idle time is the time since the last input by the user.
     If the user is active (idle time < 1 min) a period will be
     printed; if the user has left the line hanging (idle time >
     24 hrs) the word "old" will be printed.  This information is
     suppressed with the -s switch.

OPTIONS
     -q Report only user names separated by spaces.

     -H Print out a header before the output.

     -s Short form, don't check or print idle time.

     -T Print status of tty:

        +   writeable

        -   not writeable

        x   exclusive open

        ?   hung (no carrier)
