在powershell中为日志语句设置颜色并不是什么大问题。 你可以使用-ForegroundColor参数。

写一个确认消息。

Write-Host "Process executed Successfully...." -ForegroundColor Magenta

写入错误消息。

Write-Host "Sorry an unexpected error occurred.." -ForegroundColor Red

写一个进度消息。

Write-Host "Working under pocess..." -ForegroundColor Green

I'm adding an answer to address an issue noted in some comments above: that inline ansi color codes can misbehave when inside a FOR loop (actually, within any parenthesized block of code). The .bat code below demonstrates (1) the use of inline color codes, (2) the color failure that can occur when inline color codes are used in a FOR loop or within a parenthesized block of code, and (3) a solution to the problem. When the .bat code executes, tests 2 and 3 demonstrate the colorcode failure, and test 4 shows no failure because it implements the solution.

[编辑2020-04-07:我发现了另一个解决方案，可能比调用子例程更有效。将FINDSTR短语括在括号中，如下所示:

   echo success | (findstr /R success)

ENDEDIT]

注意:根据我的(有限的)经验，颜色代码问题只有在输入被管道输送到代码块中的FINDSTR之后才会出现。这就是下面的.bat重现问题的方式。颜色代码问题可能比输送到FINDSTR之后更普遍。如果有人能解释问题的本质，如果有更好的解决方法，我会很感激。

@goto :main
:resetANSI
EXIT /B
rem  The resetANSI subroutine is used to fix the colorcode
rem  bug, even though it appears to do nothing.

:main
@echo off
setlocal EnableDelayedExpansion

rem  Define some useful colorcode vars:
for /F "delims=#" %%E in ('"prompt #$E# & for %%E in (1) do rem"') do set "ESCchar=%%E"
set "green=%ESCchar%[92m"
set "yellow=%ESCchar%[93m"
set "magenta=%ESCchar%[95m"
set "cyan=%ESCchar%[96m"
set "white=%ESCchar%[97m"
set "black=%ESCchar%[30m"

echo %white%Test 1 is NOT in a FOR loop nor within parentheses, and color works right.
   echo %yellow%[Test 1] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is magenta and FINDSTR found and displayed 'success'.%yellow%
   echo %green%This is green.
echo %cyan%Test 1 completed.

echo %white%Test 2 is within parentheses, and color stops working after the pipe to FINDSTR.
(  echo %yellow%[Test 2] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is supposed to be magenta and FINDSTR found and displayed 'success'.
   echo %green%This is supposed to be green.
)
echo %cyan%Test 2 completed.

echo %white%Test 3 is within a FOR loop, and color stops working after the pipe to FINDSTR.
for /L %%G in (3,1,3) do (
   echo %yellow%[Test %%G] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is supposed to be magenta and FINDSTR found and displayed 'success'.
   echo %green%This is supposed to be green.
)
echo %cyan%Test 3 completed.

echo %white%Test 4 is in a FOR loop but color works right because subroutine :resetANSI is 
echo called after the pipe to FINDSTR, before the next color code is used.
for /L %%G in (4,1,4) do (
   echo %yellow%[Test %%G] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...

一个高级宏处理光标颜色，位置和属性的Windows 10。 有关使用方法的信息，请参阅帮助和使用示例。

支持和显示的例子:

Cursor Positioning Absolute Relative to last Cursor Position ; left right by n columns ; up down by n lines Combinations of Relative and Absolute Position. Show / Hide Cursor Cursor Graphics properties [ Color ; Foreground and Background ] Same line multicolor output Easily chain multiple VT graphics sequences. Clearing of all text on a line from a given position. Deletion of a number of characters to the right of the cursor on the current line. Optionally Save the Cursor position at the time of expansion as independent Y and X values. /Save Cursor position storing component of the macro adpated from Jeb's answer here NEW: Switching between Screen buffers.

Edit: I've included below the final usage example a command line that uses VT codes to achieve the same result as that example, to illustrate the difference in readability when using multiple Terminal sequences in the same Cursor output. NOTES On changing Buffers: Cursor position is tied to the active buffer; It is not availale when switching to an alternate buffer. When reverting to the main buffer: The cursor position originally occupied in the main buffer is restored, and the content of the alternate buffer is discarded.

::: Cout cursor Macro. Author: T3RRY ::: Filename: Cout.bat
::: OS requirement: Windows 10
::: Purpose: Facilitate advanced console display output with the easy use of Virtual terminal codes
::: Uses a macro function to effect display without users needing to memorise or learn specific
::: virtual terminal sequences.
::: Enables output of text in 255 bit color at absolute or relative Y;X positions.
::: Allows cursor to be hidden or shown during and after text output. See help for more info.

 Goto :eof

上面这个宏的另一个版本使用了一个更简单、可读性更好的结构来处理参数，可以在这里找到。

我对cmd中缺乏适当的着色感到恼火，所以我继续创建cmdcolor。它只是一个标准输出代理，它寻找一组有限的ANSI/VT100控制序列(换句话说，就像在bash中)，即echo \033[31m RED \033[0m DEFAULT | cmdcolor.exe。

使用和下载。

有一个公认的答案，已经有超过250个赞了。我仍然在贡献的原因是，许多编辑器(例如，我正在使用MS Code)不接受回显所需的转义字符，所有其他解决方案都需要一些第三方(非windows默认)软件。

只使用普通批处理命令的解决方法是使用PROMPT而不是ECHO。PROMPT命令以任何编辑器友好的方式接受转义字符作为$Echaracter序列。(简单地替换ASCII转义码中的Esc)与$E。

下面是一个演示代码:

@ECHO OFF

    :: Do not pollute environment with the %prompt.bak% variable
    :: ! forgetting ENDLOCAL at the end of the batch leads to prompt corruption
    SETLOCAL

    :: Old prompt settings backup
    SET prompt.bak=%PROMPT%

    :: Entering the "ECHO"-like section

        :: Forcing prompt to display after every command (see below)
        ECHO ON

        :: Setting the prompt using the ANSI Escape sequence(s)
        :: - Always start with $E[1A, otherwise the text would appear on a next line
        :: - Then the decorated text follows
        :: - And it all ends with $E30;40m, which makes the following command invisible
        ::   - assuming default background color of the screen
        @ PROMPT $E[1A$E[30;42mHELLO$E[30;40m

        :: An "empty" command that forces the prompt to display. 
        :: The word "rem" is displayed along with the prompt text but is made invisible
        rem

        :: Just another text to display
        @ PROMPT $E[1A$E[33;41mWORLD$E[30;40m
        rem

        :: Leaving the "ECHO"-like section
        @ECHO OFF

    :: Or a more readable version utilizing the cursor manipulation ASCII ESC sequences

        :: the initial sequence
        PROMPT $E[1A
        :: formating commands
        PROMPT %PROMPT%$E[32;44m
        :: the text
        PROMPT %PROMPT%This is an "ECHO"ed text...
        :: new line; 2000 is to move to the left "a lot"
        PROMPT %PROMPT%$E[1B$E[2000D
        :: formating commands fro the next line
        PROMPT %PROMPT%$E[33;47m
        :: the text (new line)
        PROMPT %PROMPT%...spreading over two lines
        :: the closing sequence
        PROMPT %PROMPT%$E[30;40m

        :: Looks like this without the intermediate comments:
        :: PROMPT $E[1A
        :: PROMPT %PROMPT%$E[32;44m
        :: PROMPT %PROMPT%This is an "ECHO"ed text...
        :: PROMPT %PROMPT%$E[1B$E[2000D
        :: PROMPT %PROMPT%$E[33;47m
        :: PROMPT %PROMPT%...spreading over two lines
        :: PROMPT %PROMPT%$E[30;40m

        :: show it all at once!
        ECHO ON
        rem
        @ECHO OFF

    :: End of "ECHO"-ing

    :: Setting prompt back to its original value
    :: - We prepend the settings with $E[37;40m in case
    ::   the original prompt settings do not specify color
    ::   (as they don't by default).
    :: - If they do, the $E[37;40m will become overridden, anyway.
    :: ! It is important to write this command 
    ::   as it is with `ENDLOCAL` and in the `&` form.
    ENDLOCAL & PROMPT $E[37;40m%prompt.bak%

EXIT /B 0

注意:唯一的缺点是，如果不明确地知道，这种技术与用户cmd颜色设置(颜色命令或设置)发生冲突。

——希望这能有所帮助，因为这是我在开头提到的原因唯一可以接受的解决方案。--

编辑:

根据评论，我附上另一个受@Jeb启发的片段。它:

演示如何获取和使用“Esc”字符运行时(而不是将其输入到编辑器中)(Jeb的解决方案) 使用“本机”ECHO命令 因此它不会影响本地PROMPT值 演示了给ECHO输出上色不可避免地会影响PROMPT颜色，所以颜色必须重置
