TALK(1) 						      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.

       If  you	wish  to talk to someone on you 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 :

			   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 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 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.

FILES

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

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.

       talk, otalk - talk to another user

Syntax
       talk person [ttyname]

Description
       The command is a visual communication program which copies lines from your terminal to that of another user.

       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 :
       host!user
	or
       host.user
	or
       host:user
	or
       user@host
       The form user@host 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 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 Ctrl-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; 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
       and disallow messages in order to prevent messy output.

       In order to use the program with machines on your network that may be running earlier versions of ULTRIX, you must initiate a session  with
       the  command (/usr/ucb/otalk) instead of the command You must also respond to a request from a machine running an older version of the pro-
       gram with the command. See the Restrictions section.

Examples
       The following example demonstrates how to use the command.  In this case, user1, whose system (system1) is running ULTRIX V2.2 initiates  a
       session with user2, whose system (system2) is running ULTRIX V3.0.  User1 types the following:
       system1> talk user2@system2
       The following message appears on the screen of user2:
       Message from Talk_Daemon@system2 at 12:37 ...
       talk: connection requested by user1@system1.
       talk: respond with:  otalk user1@system1
       To establish the connection user2 follows the instructions from the Talk_Daemon and types the following at the system prompt:
       system2> otalk user1@system1

Restrictions
       The  version  of  released  with ULTRIX V3.0 uses a protocol that is incompatible with the protocol used in earlier versions. Starting with
       ULTRIX V3.0, the program communicates with other machines running ULTRIX, V3.0 (and later), and machines running 4.3  BSD  or  versions	of
       UNIX based on 4.3 BSD.

       The command is not 8-bit clean. Typing in DEC Multinational Characters (DECMCS) causes the characters to echo as a sequence of a carets (^)
       followed by the character represented with its high bit cleared. This limitation makes unusable if you want to communicate using a language
       which has DECMCS characters in its alphabet.
