TALK(1)                                                                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 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.

     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,
     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/her 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 command.

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