Talk是一种视觉通信程序，可以将线路从您的终端复制到另一个用户的线路，就像即时通讯服务一样。首次调用时，talk与另一个用户计算机上的talk守护程序联系，该守护程序将在下面发送消息。

Message from TalkDaemon@his_machine...
talk: connection requested by your_name@your_machine.
talk: respond with: talk your_name@your_machine

给那个用户。此时，他然后输入

talk your_name@your_machine

只要收件人的登录名相同，接收者从哪台计算机答复都没有关系。建立通信后，两方可以同时键入内容。它们的输出将出现在单独的窗口中。键入control-L（^ L）将导致屏幕被重新打印。的擦除，压井管线，和字的擦除字符（通常1 H，为^ U，和^ W，分别地）将正常。要退出，只需键入中断字符（通常为^ C）即可；对话，然后将光标移到屏幕底部，并恢复终端恢复到之前的状态。

对话支持回滚；使用esc-p和esc-n滚动窗口，使用ctrl-p和ctrl-n滚动另一个窗口。

如果您不想接收通话请求，则可以使用mesg命令阻止它们。默认情况下，通话请求通常不会被阻止。某些命令（尤其是nroff，pine和pr）可能会暂时阻止消息以保留其自身的输出。

Talk is a visual communication program which copies lines from your terminal to that of another user, much like an instant messenger service. When first called, talk contacts the talk daemon on the other user's machine, which sends the message below.

Message from TalkDaemon@his_machine...
talk: connection requested by your_name@your_machine.
talk: respond with: talk your_name@your_machine

to that user. At this point, he then replies by typing

talk your_name@your_machine

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; their output will appear in separate windows. Typing control-L (^L) will cause the screen to be reprinted. The erase, kill line, and word erase characters (normally ^H, ^U, and ^W, respectively) will behave normally. To exit, just type the interrupt character (normally ^C); talk then moves the cursor to the bottom of the screen and restores the terminal to its previous state.

talk supports scrollback; use esc-p and esc-n to scroll your window, and ctrl-p and ctrl-n to scroll the other window.

If you do not want to receive talk requests, you may block them using the mesg command. By default, talk requests are normally not blocked. Certain commands, in particular nroff, pine, and pr, may block messages temporarily to preserve their own output.
