TALK(1)                     General Commands Manual                    TALK(1)

       talk - talk to another user

       talk username [ ttyname ]

       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  username  is
       just  the person's login name. If you wish to talk to a user on another
       host, then username is one of the following forms :
       though user@host is perhaps preferred.

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

       When first called, talk sends the message:

                     Message from TalkDaemon@his_machineattime...
                     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:

              example% talk your_name@your_machine

       It does not matter from which machine the recipient replies, as long as
       their  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 redraws the screen, 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(1) and pr(1V) disallow messages in order to prevent messy output.

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