我知道color bf命令设置了整个命令行窗口的颜色,但我想打印不同颜色的单行。

自Windows XP以来,通过使用PowerShell作为通过命名管道链接到控制台输出的子进程,可以快速有效地用cmd批处理着色。这也可以用FindStr来完成,但是PowerShell提供了更多的选项,而且似乎更快。
保持PowerShell为子进程,使用管道进行通信的主要好处是,显示要比为每一行显示启动PowerShell或FindStr快得多。
其他优点:
不需要临时文件 通过管道进行回显允许显示完整的ASCII表而不需要转义。 与fd重定向工作良好。以stderr为例,或者重定向到一个文件/其他进程。

我刚从Win 7 Home转换到Win 10 Pro,想要替换我从其他批次调用的批量,以颜色回显信息。回顾上面讨论的内容,我使用以下内容,这将直接取代我的前一批。注意在消息中添加“~”,可以使用带有空格的消息。我不用记住代码,而是用字母来代表我需要的颜色。
如果%2包含空格,则需要“…” 黑色底色:R=红色G=绿色Y=黄色W=白色
ECHO OFF

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.

:: Parameters :
:: [ PID ] : Console Process ID used as an identifier for the named pipe, launcher PID by default.
:: [ timeout ] : Subprocess max life in seconds, 300 by default. If -1, the subprocess
:: will not terminate while the process %PID% is still alive.
:: Return :
:: 0 if the child PowerShell has been successfully launched and the named pipe is available.
:: 1 if it fails.
:: 2 if we can't get a PID.
:: 3 if PowerShell is not present or doesn't work.

您可以用要打印的单词的名称创建文件,使用findstr(可以彩色打印),然后擦除该文件。试试这个例子:
@echo off
SETLOCAL EnableDelayedExpansion
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (
set "DEL=%%a"
)
call :ColorText 0a "green"
call :ColorText 0C "red"
call :ColorText 0b "cyan"
echo(
call :ColorText 19 "blue"
call :ColorText 2F "white"
call :ColorText 4e "yellow"
goto :eof
:ColorText
echo off
<nul set /p ".=%DEL%" > "%~2"
findstr /v /a:%1 /R "^$" "%~2" nul
del "%~2" > nul 2>&1
goto :eof
运行color /?得到一个颜色列表。
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
