.Sh SYNOPSIS
.Nm
.Op Fl a
.Sh DESCRIPTION
The
.Nm
command produces output similar to
.Xr who 1 ,
but for all machines on the local network.
If no report has been
received from a machine for 11 minutes then
.Nm
assumes the machine is down, and does not report users last known
to be logged into that machine.
.Pp
If a user has not typed to the system for a minute or more, then
.Nm
reports this idle time.
.Pp
The following option is available:
.Bl -tag -width indent
.It Fl a
Include all users.
By default, if a user has not typed to the system for
an hour or more, then the user will be omitted from the output.

.Bl -tag -width /var/rwho/whod.* -compact
.It Pa /var/rwho/whod.*

on the local net is large.
