NAME

write – send a message to another user
 

SYNOPSIS

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 [email protected] 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)

command. Some commands, for example
nroff(1)

and
pr(1),

may disallow writing automatically, so that your output 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 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’s the
other person’s turn to talk. The string `oo’ means that the person
believes the conversation to be over.
