write — send a message to another user


write user [tty]


The write utility 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.

You can prevent people (other than the super-user) from writing to you with the mesg(1)

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
write 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 is the other person's turn to talk. The
string ‘oo’ means that the person believes the conversation to be over.
