If hosts are specified on the command line, the sort order is equivalent to the order hosts were specified on the command line. .Pp Machines for which no status report has been received for 11 minutes are shown as being down, and machines for which no status report has been received for 4 days are not shown in the list at all. .Pp The options are as follows: .Bl -tag -width Ds .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. .It Fl l Sort by load average. .It Fl r Reverse the sort order. .It Fl t Sort by uptime. .It Fl u Sort by number of users. .El .Pp The default listing is sorted by host name. .Sh FILES .Bl -tag -width /var/rwho/whod.* -compact .It Pa /var/rwho/whod.* data files .El .Sh SEE ALSO .Xr rwho 1 , .Xr uptime 1 , .Xr rwhod 8 .Sh HISTORY A .Nm utility appeared in .Bx 4.2 .
