在这里，创建一个.bat文件，其中包含以下内容:

@echo off
REM Creating a Newline variable (the two blank lines are required!)
set NLM=^


set NL=^^^%NLM%%NLM%^%NLM%%NLM%
REM Example Usage:
echo There should be a newline%NL%inserted here.

echo.
pause

您应该会看到如下输出:

There should be a newline
inserted here.

Press any key to continue . . .

显然，您只需要REM语句之间的代码。

可以使用@echo (@echo +[空间]+[不安全空间])

注:不安全空间可用Alt+0160获取

希望能有所帮助。

嗯，你是对的，我需要它在一个Makefile中，它在那里工作得很好。我想我的答案不适合批处理文件…我的坏。

经过一个不眠之夜，在阅读了这里所有的答案后，在阅读了大量的SS64 > CMD和大量的尝试和错误后，我发现:

(几乎)终极解决方案

博士TL;

．.． 对于早期采用者。

设置换行环境变量…

．.． 在当前CMD会话中

:: Sets newline variables in the current CMD session
set \n=​^&echo:
set nl=​^&echo:

．.． 当前用户

:: Sets newline variables for the current user [HKEY_CURRENT_USER\Environment]
setx \n ​^&echo:
setx nl ​^&echo:

．.． 对于本地机器

:: Sets newline variables for the local machine [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]
setx \n ​^&echo: /m 
setx nl ​^&echo: /m 

为什么只是快?

它不适用于在同一打印行中没有配对(开引号和闭引号)的双引号，除非唯一未配对的双引号是文本的最后一个字符，例如:

works: ""echo %\n%...after "newline". Before "newline"...%\n%...after "newline" (paired in each printed line) works: echo %\n%...after newline. Before newline...%\n%...after newline" (the only unpaired double-quote is the last character) doesn't work: echo "%\n%...after newline. Before newline...%\n%...after newline" (double-quotes are not paired in the same printed line) Workaround for completely double-quoted texts (inspired by Windows batch: echo without new line): set BEGIN_QUOTE=echo ^| set /p !=""" ... %BEGIN_QUOTE% echo %\n%...after newline. Before newline...%\n%...after newline"

它适用于完全单引号的文本，如:

echo '%\n%...after newline. Before newline...%\n%...after newline'

附加值:转义字符

:: Escape character - useful for color codes when 'echo'ing
:: See https://learn.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences#text-formatting
set ESC=

的原因

The version in Ken's answer works apparently (I didn't try it), but is somehow...well...you see: set NLM=^ set NL=^^^%NLM%%NLM%^%NLM%%NLM% The version derived from user2605194's and user287293's answer (without anything between '=' and '^'): set nl=^&echo: set \n=^&echo: works partly but fails with the variable at the beginning of the line to be echoed: > echo %\n%Hello%\n%World! echo & echo:Hello & echo:World! echo is ON. Hello World due to the blank argument to the first echo. All others are more or less invoking three echos explicitely. I like short one-liners.

背后的故事

为了防止set \n=^&echo:在这里的回答中显示空白(并打印其状态)，我第一次记住Alt+255用户是在Novell广泛使用网络和使用437和850等代码页的时候。但是0d255/0xFF在现在的Unicode中是大写的大写字母Y。

然后我想起来Unicode中有比普通的0d32/0x20更多的空格，但它们都被认为是空格，并导致与›␣相同的行为。

But there are even more: the zero width spaces and joiners which are not considered as whitespaces. The problem with them is, that you cannot C&P them since with their zero width there's nothing to select. So, I copied one that is close to one of them, the hair space (U+200A) which is right before the zero width space (U+200B) into Notepad++, opened its Hex-Editor plugin, found its bit representation E2 80 8A and changed it to E2 80 8B. Success! I had a non-whitespace character that's not visible in my \n environment variable.

注意，这不会在控制台工作，因为它将模拟一个escape键和清除行。

使用这段代码，将<ESC>替换为0x1b转义字符或使用这个Pastebin链接:

:: Replace <ESC> with the 0x1b escape character or copy from this Pastebin:
:: https://pastebin.com/xLWKTQZQ

echo Hello<ESC>[Eworld!

:: OR

set "\n=<ESC>[E"
echo Hello%\n%world!

在windows 10的虚拟终端序列中，存在高度控制光标位置的方法。

要定义转义序列0x1b，可以使用以下方法:

@Echo off
 For /f %%a in ('echo prompt $E^| cmd')Do set \E=%%a

在字符串之间输出一个换行符:

<nul set /p "=Hello%\E%[EWorld"

输出n个换行符，其中n被整数替换。

<nul set /p "=%\E%[nE"

Ken和Jeb的解决方案效果很好。

但是新行只生成一个LF字符，我需要CRLF字符(Windows版本)。

为此，在脚本的末尾，我已经将LF转换为CRLF。

例子:

TYPE file.txt | FIND "" /V > file_win.txt
del file.txt
rename file_win.txt file.txt
