更改窗口命令提示符字符串

Question

I want to change the command prompt string in a windows command prompt?

For example.

C:\\current\\path -> $CustomPrompt>

If possible, I would prefer the solution to make use of the winapi. I already looked at some of the console functions, but I cannot find any that I would assume wold manipulate the prompt string? Does anyone know how to do this?

Command Prompt String is definied as environmental variable PROMPT. You can modify this variable using setenv() function from cstdlib :

#include <stdlib.h>

//...

setenv("PROMPT", "$A$A", true);

This will, for example, set prompt string to '&&' (double ampersand). For more interesting examples check this out.

EDIT: There is a way to achieve this without need to restart command interpreter. Create following batch file:

@echo off
break off
title custom command prompt
color 0a
cls

:cmd
 set /p cmd=command:

 %cmd%
 echo.
 goto cmd

Lets name it "change_prompt.bat" Then, in your c++ code execute the batch file:

system("change_prompt.bat");

As a result, prompt will look like this:

As you can see, this changes:

• prompt window title
• prompt color
• prompt string
