write — send a
message to another user
write allows you to communicate with other
users, by copying lines from your terminal to theirs.
When you run the
write command, the user
you are writing to gets a message of the form:
Message from yourname@yourhost on yourtty at hh:mm ...
Any further lines you enter will be copied to the specified user's
terminal. If the other user wants to reply, they must run
write as well.
When you are done, type an end-of-file or interrupt character. The other user will see the message “EOF” indicating that the conversation is over.
If the user you want to write to is logged in on more than one
terminal, you can specify which terminal to write to by specifying the
terminal name as the second operand to the
command. Alternatively, you can let
write select one
of the terminals - it will pick the one with the shortest idle time. This is
so that if the user is logged in at work and also dialed up from home, the
message will go to the right place.
The traditional protocol for writing to someone is that the string “-o”, either at the end of a line or on a line by itself, means that it's the other person's turn to talk. The string “oo” means that the person believes the conversation to be over.

Version 2 AT&T UNIX.
The “EOF” message seen when the other
write terminates is indistinguishable from that
party simply typing “EOF” to make you believe that any future
messages did not come from them. Especially messages such as:
 Done rm -rf *
