Color for the PROMPT (just the PROMPT proper) in cmd.exe and PowerShell?

问题

So in Bash you just configure PS1 to add colors to your prompt. I'm talking about the prompt proper, not the color of the foreground (text) or the background. And it's really easy in Bash and it helps a lot if you need to find your commands in a sea of messy text output.

Can you achieve the same for cmd.exe, or as a fallback, for PowerShell? A colored prompt?

I don't know if it could be done in the old days before Win32 by loading ANSI.SYS. I think that was just to make the foreground and the background colorful. But I might be wrong. And anyway, those days are gone, and in our modern times (I know), we're using cmd.exe, or PowerShell.

I know both cmd.exe and PowerShell are capable of colored output. For cmd.exe, just run color /? to find out. But my question is not about the foreground and the background, that's all known to humankind - it's about just changing the prompt color for cmd.exe, probably via the PROMPT environment variable as via the PS1 variable for Bash? Is it possible?

And no, Cygwin is not an alternative for this. I'm a Cygwin user with MinTTY and all, and I love it. But I still want my cmd.exe prompt colored, too.

follow this link. There's an ANSI hack developped for the CMD.exe shell

I've tried it on my win 7 professional SP1 and works like a charm

You can add a Prompt function to your profile in Powershell to pretty much do whatever you want with the prompt. So for instance something like this:

function prompt
{
    Write-Host "PS $(get-location)>"  -nonewline -foregroundcolor Magenta
    return ' '
}

To open or create your PowerShell profile, run this:

if(Test-Path $profile){notepad $profile}else{New-Item -path $profile -type file -force}

This is all good information but an important thing that I didn't see addressed is how to make the custom prompt appear each time you run a command prompt. In older Windows, such as XP and before, you would put the PROMPT environment variable in the AUTOEXEC.BAT file but in Windows 7 through Windows 10, you would make it permanent as follows:

Open the Run prompt by using the Windows key + R
Type "systempropertiesadvanced" (without the quotes) and hit ENTER
This will open the System Properties dialog box (You can also right click My Computer and choose Properties to get this)
Select the "Advanced" Tab at the top
Choose "Environment Variables" near the bottom
In the lower area, in the "System variables" area, look and see if you currently have a variable called "Prompt" (capitalization doesn't matter)
If so, edit the prompt variable and your changes with be permanent
If not, click "New" near the bottom and for Variable name, enter PROMPT and for the variable value, whatever you want it to be. The default prompt has a variable value of $P$G
Click OK
Run the command prompt to test
DONE
Note: I use a custom command prompt which looks like the Texas flag. The Variable value for this is: $e[1;44m*$e[41m▀▀$e[0;1m $P$G

(The white bar is made by holding down ALT and typing 223 on the keypad on the right. There are two of these characters in this prompt.)

You can use multiple colors (very useful for identifying components of your prompt, typical in Unix):

function prompt {
    Write-Host ("@") -NoNewLine -ForegroundColor Magenta
    Write-Host ("$env:COMPUTERNAME") -NoNewLine -ForegroundColor Green
    Write-Host (":") -NoNewLine -ForegroundColor Magenta
    Write-Host ($(Get-Location)) -NoNewLine -ForegroundColor Green
    Write-Host (">") -NoNewLine -ForegroundColor Red
    return " "
}

(COMPUTERNAME was explicitly written here, but it actually gets replaced by the value of the environment variable).

And you can add random colors (taken from here; this has a similar version; both have other very interesting tweaks):

function prompt
{
    $random = new-object random
    $color=[System.ConsoleColor]$random.next(1,16)
    Write-Host ("PS " + $(get-location) +">") -nonewline -foregroundcolor $color
    return " "
}

Building on @KriZ's answer, the ANSI escape sequences work perfectly in Windows 10 cmd.exe as of 2019. Didn't need to explicitly call out ansi.sys or copy any files. It just worked out of the box in Windows 10.

For example,

set PROMPT=$E[1;37m[user@machine:$E[1;35m$P ]$$ $E[1;37m

Produces:

(Notice the space after the final $)

Everything before the drive is colored in bold white and the drive/folder is bold pink, and everything after the final $ is bold white.

The format for the colors is:

$E[bold_or_not;colorm

With m always following the color number. bold_or_not = 0 or 1. Here's a guide for the colors:

0     Turn Off Attributes
1     High Intensity
2     Normal Intensity
4     Underline (mono only)
5     Blink
7     Reverse Video
8     Invisible
30    Black
31    Red
32    Green
33    Yellow
34    Blue
35    Magenta
36    Cyan
37    White
40    Black
41    Red
42    Green
43    Yellow
44    Blue
45    Magenta
46    Cyan
47    White
