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。
当前回答
为非windows 10用户提供了一个不需要调用标签的选项,避免了这样做带来的延迟。
下面是findstr colorprint例程的宏版本

其他回答
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%

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

@ECHO OFF
:: Reset the `PROMPT` color

:: ! Resetting `PROMPT` color this way extends the `PROMPT`
:: by the initial `$E[37;40m` sequence every time the script runs.
:: - Better solution then would be to end every (or last) `ECHO` command

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。
下面是一个示例代码:
::
:: Launch a PowerShell child process in the background linked to the console and
:: earing through named pipe PowerShellCon_%PID%
::
:: 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.

可以使用color命令更改整个控制台的颜色
Color 0F
是黑白的
Color 0A
是黑色和绿色的
Solution for changing the foreground and background colors and writing without new lines. It does not create any temporary files. No special editors are required, so Notepad can be used for editing. The first parameter for the :color subroutine is the color code, the rest of the (optional) parameters are the text to display. If the last parameter is $ then a new line is written at the end. The color codes are the same as for the color command. The :echo subroutine can be used to display a text without new line (unlike regular echo).

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。
