script to develope

Hi
All,

can you please help me to develope this script?
Any help will be appreciated.

Sender Broadcasting Same Message to Multiple Processes

Write two programs, a sender and a receiver. The sender will take text entered
at the keyboard, and broadcast it as a message to multiple copies of the
receiver program. Upon receipt of a message, a receiver outputs its program
name(argv[0]) and the message content. The sender loops sending entered text as
message until end of file is encountered at the keyboard. Upon EOF the sender,
transmits a delimiter message to all receivers. As each receiver finishes with
the message queue, it transmits a message back to sender. After receiving such
an acknowledge message from every receiver, the sender removes the message
queue.

eg.

assume the sender's filename is---msg_wall_s
receiver's filename is ---msg_wall_r

$msg_wall_s
Enter message to be sent to all receivers: abcde
msg_wall_r0 received 'abcde'
msg_wall_r1 received 'abcde'
msg_wall_r2 received 'abcde'
Enter message to be sent to all receivers: xyz
msg_wall_r0 received 'xyz'
msg_wall_r1 received 'xyz'
msg_wall_r2 received 'xyz'
Enter message to be sent to all receivers: <CONTROL/D>
msg_wall_r0 received 'EOF'
msg_wall_r1 received 'EOF'
msg_wall_r2 received 'EOF'
$

Thanks,
Vish

(1) this looks suspiciously like homework

(2) this does not look like a script, it looks more like a C program going by the reference to argv[0]

How do you think you are going to do it?

What bits of functionality do you need?

How are you going to tie them together?

What language are you going to implement this in?
