talk is a visual communication program which copies lines from your terminal to that of another user.
The command line arguments are as follows:
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 login-name is the same. Once communication is established, the two parties may type simultaneously, with their output appearing in separate windows. Typing C-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. At the outset talking is allowed. Certain commands, in particular nroff and pr, disallow messages in order to prevent messy output.
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.
