WRITE(1)		  BSD General Commands Manual		      WRITE(1)

     write -- send a message to	another	user

     write user	[ttyname]

     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	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	termi-
     nal.  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.

     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 be-
     lieves the	conversation to	be over.

     mesg(1), talk(1), wall(1),	who(1)

     A write command appeared in Version 1 AT&T	UNIX.

     The sender's LC_CTYPE setting is used to determine	which characters are
     safe to write to a	terminal, not the receiver's (which write has no way
     of	knowing).

     The write utility does not	recognize multibyte characters.
