WRITE(1) User Commands WRITE(1)
NAME
write - send a message to another user
write user [ttyname]
DESCRIPTION
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.
You can prevent people (other than the superuser) from writing to you
with the mesg(1) command. Some commands, for example nroff(1) and
pr(1), may automatically disallow writing, so that the output they
produce isn’t overwritten.
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 giving 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’s the
other person’s turn to talk. The string oo means that the person
believes the conversation to be over.
