        !            12: .SH DESCRIPTION
        !            13: \fIWho,\fP without any argument, reads the /etc/utmp file,
        !            14: and lists the login name, terminal name, and login time for each
        !            15: user currently logged into the system.  If a single argument is
        !            16: given, \fIwho\fP uses that file instead of /etc/utmp.  Typically,
        !            17: that file will be /usr/adm/wtmp, which contains a record of all
        !            18: the logins, logouts, crashes, shutdowns and time changes since it
        !            19: was created.  In either case, each login will be listed with the
        !            20: user name, the terminal name (with "/dev/" suppressed), login date
        !            21: and time, and, if applicable, the host logged in from.
        !            22: .PP
        !            23: If /usr/adm/wtmp is being used as the file, the user name may be empty
        !            24: or one of the special characters '|', '}' and '~'.  Logouts produce
        !            25: an output line without any user name.  For more information on the
        !            26: special characters, see utmp(5).
        !            27: .PP
        !            28: With two arguments, as in `who am I' (and also `who are you'),
        !            29: \fIwho\fP tells you who you are logged in as.
