WHO(1)                  GENIX Programmer's Manual                  WHO(1)



      NAME
           who - who is on the system

      SYNOPSIS
           who [ who-file ] [ am I ]

      DESCRIPTION
           Who, without an argument, lists the login name, terminal  name,  and
           login time for each current UNIX user.

           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  since  it was created.  Then who lists logins, logouts,
           and crashes since the creation of the  wtmp  file.   Each  login  is
           listed  with 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 two arguments, as in `who am I' (and also `who are  you'),  who
           tells who you are logged in as.
