TALK(1) 						    BSD General Commands Manual 						   TALK(1)

NAME
     talk -- talk to another user

SYNOPSIS
     talk person [ttyname]

DESCRIPTION
     talk 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'.

     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, while your erase, kill, and word kill characters 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) command.  At the outset talking is allowed.  Certain commands, in particu-
     lar nroff(1) and pr(1), disallow messages in order to prevent messy output.

ENVIRONMENT
     If the TALKHOST environment variable is set, its value is used as the hostname the talk packets appear to be originating from.  This is use-
     ful if you wish to talk to someone on another machine and your internal hostname does not resolve to the address of your external interface
     as seen from the other machine.

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

SEE ALSO
     mail(1), mesg(1), who(1), write(1)

HISTORY
     The talk command appeared in 4.2BSD.

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