WRITE(1)                         User Commands                        WRITE(1)
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 mes-
       sage 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 ter-
       minal.  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 pro-
       duce isn't overwritten.
       If  the  user you want to write to is logged in on more than one termi-
       nal, 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.
