    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.

    Options available:

    person
    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'
    ttyname
    If you wish 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' or `pts/X'

    When first called, talk contacts the talk daemon on the other user's machine, which 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 that user. At this point, he then replies 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; their output will appear in separate windows. Typing control-L (^L) will cause the screen to be reprinted. The erase, kill line, and word erase characters (normally ^H, ^U, and ^W respectively) will behave normally. To exit, just type the interrupt character (normally ^C); talk then moves the cursor to the bottom of the screen and restores the terminal to its previous state.

    As of netkit-ntalk 0.15 talk supports scrollback; use esc-p and esc-n to scroll your window, and ctrl-p and ctrl-n to scroll the other window. These keys are now opposite from the way they were in 0.16; while this will probably be confusing at first, the rationale is that the key combinations with escape are harder to type and should therefore be used to scroll one's own screen, since one needs to do that much less often.

    If you do not want to receive talk requests, you may block them using the mesg(1) command. By default, talk requests are normally not blocked. Certain commands, in particular nroff(1), pine(1), and pr(1), may block messages temporarily 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 protocol used to communicate with the talk daemon is braindead.

    Also, the version of talk(1) released with BSD 4.2 uses a different and even more braindead protocol that is completely incompatible. Some vendor Unixes (particularly those from Sun) have been found to use this old protocol.

    Old versions of talk may have trouble running on machines with more than one IP address, such as machines with dynamic SLIP or PPP connections. This problem is fixed as of netkit-ntalk 0.11, but may affect people you are trying to communicate with.  

    HISTORY

    The talk command appeared in BSD 4.2
