rusers - Display a list of users who are logged in to a remote machine
rusers [-ahilu] host...
-a Give a report for a machine even if no users are logged in.
-h Sort alphabetically by host name.
-i Sort by idle time.
-l Give a longer listing in the style of who(1).
-u Sort by number of users.
The rusers command displays information about users and processes running
on remote machines. The listing is in the order in which responses are
received, but this order can be changed by specifying one of the options
listed in the OPTIONS section.
By default the rusers command prints the names of the users logged in.
When the -l option is given, additional information is printed for each
user, as follows:
userid hostname:terminal login date login time idle time login host
If hostname and login host are the same value, the login host field is
not displayed. Likewise, if hostname is not idle, the idle time is not
displayed. A remote host only responds if it is running the rusersd daemon,
which may be started from the inetd daemon or the listen function.
Commands: who(1), inetd(8)
