TALK(1)             UNIX Programmer's 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.

     If you wish to talk to someone on you own machine, then per-
     son is just the person's login name. If you wish to talk to
     a user on another host, then person is of the form :

			 host!user  or
			 host.user  or
			 host:user  or
			 user@host

     though host@user is perhaps preferred.

     If you want to talk to a user who is logged in more than
     once, the ttyname argument may be used to indicate the
     appropriate terminal name.

     When first called, it 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 reci-
     pient 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 con-
     trol L will cause the screen to be reprinted, while your
     erase, kill, and word kill characters will work in talk as
     normal.  To exit, just type your interrupt character; talk
     then moves the cursor to the bottom of the screen and
     restores the terminal.

     Permission to talk may be denied or granted by use of the
     mesg command.  At the outset talking is allowed.  Certain
     commands, in particular nroff and pr(1) disallow messages in
     order to prevent messy output.

BUGS
     The version of talk(1) released with 4.3BSD uses a protocol
     that is incompatible with the protocol used in the version
     released with 4.2BSD.
