## 问题 **(**The Question**)** ##

SuperUser reader Erty is curious:

超级用户读者Erty很好奇：

> Is there a name for the text that shows up at the front of each command at the Command Line Interface. For example, in Ubuntu when I start up a terminal, it says:
> 
> 命令行界面上每个命令的开头是否显示文本的名称。 例如，在Ubuntu中，当我启动一个终端时，它说：
> 
> username@computer:~$ And in Windows:
> 
> username @ computer：〜$在Windows中：
> 
> C:\\Users\\Username> Is there a formal way to refer to that text?
> 
> C：\\ Users \\ Username>是否有引用该文本的正式方法？
> 
> Thanks in advance!
> 
> 提前致谢！

> It’s called ‘the prompt’

> 叫做“提示”

> In linux, you could be more specific and say “the bash prompt” in the case of the bash shell, or for the KSH shell, The KSH (korn shell) prompt etc. In Windows you can change the prompt with the PROMPT command.
> 
> 在linux中，您可能更具体，在bash shell的情况下说“ bash提示符”，对于KSH shell，则说KSH(korn shell)提示等。在Windows中，您可以使用PROMPT命令更改提示。
> 
> In windows, you could be more specific and say “the C prompt”, and the prompt in windows is most famously C:\\> or C:\\something…> so you can see how it gets that name. A techie might’ve frustratingly said to a user on the phone “Do you get the C prompt?”. While saying it as C prompt, some write it as The C:\\ prompt or The C: prompt. One wouldn’t call it that when it was A: or D: (which you get when you boot DOS off floppy or cd drive, or you change to one those drives from the command prompt) and nobody talks of the A prompt or the D prompt, only the famous one, the C prompt.
> 
> 在Windows中，您可能更具体，说“ C提示符”，而Windows中的提示符最著名的是C：\\>或C：\\ something…>，因此您可以看到它如何获得该名称。 一个技术人员可能会在电话上沮丧地对用户说：“您收到C提示了吗？”。 当说它为C提示符时，有人将其写为C：\\提示符或C：提示符。 当它是A：或D :(从软盘或CD驱动器启动DOS，或者从命令提示符更改为这些驱动器之一)时，不会有人称呼它，而没人会说A提示符或D提示，只有著名的一个，C提示。
