RWALL(1) UNIX Programmer's Manual RWALL(1) NAME rwall - write to all users over a network SYNOPSIS rwall host1 host2 ... rwall -n netgroup1 netgroup2 ... rwall -h host -n netgroup DESCRIPTION _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 -n option, it sends to the specified network groups, which are defined in _n_e_t_g_r_o_u_p(5). A machine can only receive such a message if it is running _r_w_a_l_l_d(8), which is normally started up from /_e_t_c/_s_e_r_v_e_r_s by the daemon _i_n_e_t_d(8). FILES /etc/servers SEE ALSO wall(1), netgroup(5), rwalld(8), shutdown(8) BUGS 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 thru to a heavily loaded machine. Printed 12/27/86 1 February 1985 1
