+.SH NAME
+.BR who
+\- display who is logged in
+.SH SYNOPSIS
+.BR who
+.RB [ am
+.BR I ]
+.RI [ file ]
+.SH DESCRIPTION
+The utility
+.BR who
+displays
+a list of all users currently logged on, showing for each user
+the login name,
+tty name, the date and time of login, and hostname if not local.
+.LP
+Available options:
+.RS
+.IP "\fBam I\fR"
+Returns the invoker's real user name. 
+.IP \fIfile\fR
+By default,
+.BR who
+gathers information from the file
+.BR /var/run/utmp .
+An alternate
+.BR file
+may be specified which is usually
+.BR /var/run/wtmp
+(or
+.BR /var/run/wtmp.[0-6]
+depending on site policy as
+.BR wtmp
+can grow quite large and daily versions may or may not
+be kept around after compression by
+.BR ac (8)).
+The
+.BR wtmp
+file contains a record of every login, logout,
+crash, shutdown and date change
+since
+.BR wtmp
+was last truncated or
+created.
+.RE
+.LP
+If
+.BR /var/log/wtmp
+is being used as the file, the user name may be empty
+or one of the special characters '|', '}' and '~'.  Logouts produce
+an output line without any user name.  For more information on the
+special characters, see
+.BR utmp (5).
