+/// Check who is logged in on local machines.

+/// The `rwho` command produces output similar to `who`, but for all machines on the local network.
+/// If no report has been received from a machine for 11 minutes then rwho assumes the machine is down,
+/// and does not report users last known to be logged into that machine.
+///
+/// If a users hasn't typed to the system for a minute or more, then rwho reports this idle time.
+/// If a user hasn't typed to the system for an hour or more,
+/// then the user will be omitted from the output of `rwho` unless the `-a` flag is given.
