talk - talk to another user
talk person [ 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 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
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
Permission to talk may be denied or granted by use of the mesg command.
