talk person [ttyname]
Talk to another user. person is either the login name of someone on your own machine or user@host on another host. To talk to a user who is logged in more than once, use ttyname to indicate the appropriate terminal name. Once communication has been established, the two parties may type simultaneously, with their output appearing in separate windows. To redraw the screen, type Ctrl-L. To exit, type your interrupt character; talk then moves the cursor to the bottom of the screen and restores the terminal.
