- _R_w_a_l_l reads a message from standard input until end-of-file. It then
- sends this message, preceded by the line ``Broadcast Message ...'', to
- all users logged in on the specified host machines. With the ----nnnn option,
- it sends to the specified network groups, which are defined in
- _n_e_t_g_r_o_u_p(4).
-
- A machine can only receive such a message if it is running _r_w_a_l_l_d(1m),
- which is normally started up by the daemon _i_n_e_t_d(1m).

- The timeout is fairly short in order to be able to send to a large group
- of machines (some of which may be down) in a reasonable amount of time.
- Thus the message may not get through to a heavily loaded machine.
