TALK(1)			FreeBSD	General	Commands Manual		       TALK(1)

NAME
     talk -- talk to another user

SYNOPSIS
     talk person [ttyname]

DESCRIPTION
     The talk utility is a visual communication	program	which copies lines
     from your terminal	to that	of another user.

     Options available:

     person   If you wish to talk to someone on	your own machine, then person
	      is just the person's login name.	If you wish to talk to a user
	      on another host, then person is of the form `user@host' or
	      `host!user' or `host:user'.

     ttyname  If you wish to talk to a user who	is logged in more than once,
	      the ttyname argument may be used to indicate the appropriate
	      terminal name, where ttyname is of the form `ttyXX'.

     When first	called,	talk sends the message
	   Message from	TalkDaemon@his_machine...
	   talk: connection requested by your_name@your_machine.
	   talk: respond with: talk your_name@your_machine

     to	the user you wish to talk to.  At this point, the recipient of the
     message should reply by typing

	   talk	 your_name@your_machine

     It	doesn't	matter from which machine the recipient	replies, as long as
     his login-name is the same.  Once communication is	established, the two
     parties may type simultaneously, with their output	appearing in separate
     windows.  Typing control-L	`^L' will cause	the screen to be reprinted.
     Typing control-D `^D' will	clear both parts of your screen	to be cleared,
     while the control-D character will	be sent	to the remote side (and	just
     displayed by this talk client).  Your erase, kill,	and word kill charac-
     ters will behave normally.	 To exit, just type your interrupt character;
     talk then moves the cursor	to the bottom of the screen and	restores the
     terminal to its previous state.

     Permission	to talk	may be denied or granted by use	of the mesg(1) com-
     mand.  At the outset talking is allowed.

FILES
     /etc/hosts	    to find the	recipient's machine
     /var/run/utmp  to find the	recipient's tty

SEE ALSO
     mail(1), mesg(1), wall(1),	who(1),	write(1), talkd(8)

BUGS
     The version of talk released with 4.3BSD uses a protocol that is incom-
     patible with the protocol used in the version released with 4.2BSD.

     Multibyte characters are not recognized.

HISTORY
     The talk command appeared in 4.2BSD.

     In	FreeBSD	5.3, the default behaviour of talk was changed to treat	local-
     to-local talk requests as originating and terminating at localhost.
     Before this change, it was	required that the hostname (as per
     gethostname(3)) resolved to a valid IPv4 address (via gethostbyname(3)),
     making talk unsuitable for	use in configurations where talkd(8) was bound
     to	the loopback interface (normally for security reasons).
