write: Write To

For line mode terminals,

write user_b

is used. As with talk, write is used to communicate between logged-on users. BUT unlike talk, write is not ``conversational".

When write is invoked, the user types in the message to be sent: every time a carriage return is typed, that line is sent to the remote user. $<$CTL-D$>$ is used to get out of line mode.
