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 :
host!user host.user host:user 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.
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
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.
