如何从批处理文件输出中插入换行符?
我想做的事情是:
echo hello\nworld
这将输出:
hello
world
当前回答
要批量地开始新一行，你所要做的就是添加“echo[”，像这样:
echo Hi!
echo[
echo Hello!
其他回答
Use:
echo hello
echo:
echo world
当回显某些内容以重定向到文件时，多个回显命令将不起作用。我认为“>>”重定向器是一个不错的选择:
echo hello > temp echo world >> temp
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

| Use a text editor for C&P that supports Unicode, e.g. Notepad++! |
设置换行环境变量…

Do not edit anything between '=' and '^'! (There's a character in between though you don't see it. Neither here nor in edit mode. C&P works here.) |
:: Sets newline variables in the current CMD session
set \n=^&echo:
set nl=^&echo:

Do not edit anything between (the second) '␣' and '^'! (There's a character in between though you don't see it. Neither here nor in edit mode. C&P works here.) |
:: Sets newline variables for the current user [HKEY_CURRENT_USER\Environment]
setx \n ^&echo:
setx nl ^&echo:

Do not edit anything between (the second) '␣' and '^'! (There's a character in between though you don't see it. Neither here nor in edit mode. C&P works here.) |
:: 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
| Note |
|---|
There's a character after the '=' but you don't see it here but in edit mode. C&P works here. |
:: Escape character - useful for color codes when 'echo'ing

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.
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。
这对我来说很有效，不需要延迟扩展:
@echo off
(
echo ^<html^>
echo ^<body^>
echo Hello
echo ^</body^>
echo ^</html^>
)
pause
它像这样写输出:
<html>
<body>
Hello
</body>
</html>
