Frequently asking questi*** about the **allest and most subtle elements of your computing experience can yield interesting insights into computers and their history. Today we look at the little block of text that sits at the front of the command line.

问题

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:

username@computer:~$ And in Windows:

C:\Users\Username> Is there a formal way to refer to that text?

Thanks in advance!

那一点点叫什么？

答案

超级用户贡献者Barlop提供了一些见解：

It’s called ‘the prompt’

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.

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.
