2 Enter the message you want to send.

3 Press the "control-d" key at the end, the message is displayed in the user's control window.

4 for receiving a message, you can set whether to allow others to send messages to you.

Instruction format: MESG N[y]

%write liuxhello! Everybody, I ' llcome.
%

Message displayed in User Control window:

Message from Liux on TTYP1 at 10:00...hello! Everybody,i ' Llcome. EOF

When using a window system such as CDE or openwindows, each window is considered a separate login, and if the user logs in more than once, the message is sent directly to the control window.
