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

就像Grimtron建议的那样-这里有一个简单的例子来定义它:

@echo off
set newline=^& echo.
echo hello %newline%world

输出

C:\>test.bat
hello
world

其他回答

Use:

echo hello
echo:
echo world

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!

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!

如果需要在可以传递给变量的字符串中使用著名的\n,可以编写如下Hello.bat脚本所示的代码:

@echo off
set input=%1
if defined input (
    set answer=Hi!\nWhy did you call me a %input%?
) else (
    set answer=Hi!\nHow are you?\nWe are friends, you know?\nYou can call me by name.
)

setlocal enableDelayedExpansion
set newline=^


rem Two empty lines above are essential
echo %answer:\n=!newline!%

通过这种方式,多行输出可以在一个地方准备,甚至在其他脚本或外部文件中,并在另一个地方打印。

The line break is held in newline variable. Its value must be substituted after the echo line is expanded so I use setlocal enableDelayedExpansion to enable exclamation signs which expand variables on execution. And the execution substitutes \n with newline contents (look for syntax at help set). We could of course use !newline! while setting the answer but \n is more convenient. It may be passed from outside (try Hello R2\nD2), where nobody knows the name of variable holding the line break (Yes, Hello C3!newline!P0 works the same way).

上面的例子可以细化为子程序或独立批处理,如调用:mlecho Hi\ i 'm your computer:

:mlecho
setlocal enableDelayedExpansion
set text=%*
set nl=^


echo %text:\n=!nl!%
goto:eof

请注意,额外的反斜杠不会阻止脚本解析\n子字符串。

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"
