在Ken的回答中添加一个变量，它显示了环境变量的设置值，其中包含新行。

我们使用此方法将错误条件附加到VAR中的字符串中，然后在所有错误检查输出的末尾将所有错误汇总到文件中。

这不是完整的代码，只是一个示例。

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
:: the two blank lines are required!
set NLM=^


set NL=^^^%NLM%%NLM%^%NLM%%NLM%
:: Example Usage:

Set ErrMsg=Start Reporting:
:: some logic here finds an error condition and appends the error report
set ErrMsg=!ErrMsg!!NL!Error Title1!NL!Description!NL!Summary!NL!

:: some logic here finds another error condition and appends the error report
set ErrMsg=!ErrMsg!!NL!Error Title2!NL!Description!NL!Summary!NL!

:: some logic here finds another error condition and appends the error report
set ErrMsg=!ErrMsg!!NL!Error Title3!NL!Description!NL!Summary!NL!

echo %ErrMsg%
pause
echo %ErrMsg% > MyLogFile.log

日志和屏幕输出看起来像这样…

有一个标准的功能echo:在cmd/bat-files中写入空行，这模拟了cmd-output中的新行:

@echo off
echo line1
echo:
echo line2

or

@echo line1 & echo: & echo line2

上面引用的cmd-file输出:

line1

line2

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

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!

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。
