rwall(NADM)


rwall -- write to all users over a network

Syntax

rwall hostname ...

rwall -n netgroup ...

rwall -h host -n netgroup

Description

rwall 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 netgroup(NF).

A machine can only receive such a message if it is running rwalld(NADM).

rwalld is stopped and started by rpcinit(NADM).

Limitations

The timeout is fairly short in order 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.
