## talk

    talk user [@hostname] [tty]

Exchange typed communication with another `user` who is on the local machine or on machine `hostname`. talk might be useful when you're logged in via modem and need something quickly, making it inconvenient to telephone or send e-mail. talk splits your screen into two windows. When connection is established, you type in the top half while `user`'s typing appears in the bottom half. Type CTRL-L to redraw the screen and CTRL-D (or interrupt) to exit. If `user` is logged in more than once, use `tty` to specify the terminal line.
