TALK(1)             UNIX Programmer's Manual		  TALK(1)



[1mNAME
     [0mtalk - talk to another user

[1mSYNOPSIS
     talk [0mperson [ ttyname ]

[1mDESCRIPTION
     [0m_T_a_l_k 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 _p_e_r_-
     _s_o_n is just the person's login name. If you wish to talk to
     a user on another host, then _p_e_r_s_o_n is of the form :

			 _h_o_s_t!_u_s_e_r  or
			 _h_o_s_t._u_s_e_r  or
			 _h_o_s_t:_u_s_e_r  or
			 _u_s_e_r@_h_o_s_t

     though _u_s_e_r@_h_o_s_t is perhaps preferred.

     If you want to talk to a user who is logged in more than
     once, the _t_t_y_n_a_m_e 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; _t_a_l_k
     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
     _m_e_s_g command.  At the outset talking is allowed.  Certain
     commands, in particular _n_r_o_f_f and _p_r(1) disallow messages in
     order to prevent messy output.
