DOS：多行字符串工作 [英] DOS: Working with multi-line strings

问题描述

我试图创建一个绕过一个字符串线将其送至但它不工作了一个批处理文件。字符串的继续作为一个新的命令执行。

I'm trying to create a batch file which passes around a string with line feeds in it but its not working out. The continuation of the string is executed as a new command.

反正是有恩code换行或使这项工作？

Is there anyway to encode a line feed or make this work?

推荐答案

您可以创建一个插入符（要求使用一个空行）直接多行字符串。

You can create directly multiline strings with the caret (one empty line is required).

setlocal EnableDelayedExpansion
set multiLine=This is a ^

multiline text^

line3
echo !multiLine!

或者你可以先创建一个换行符。

Or you can create first a newline character.

setlocal EnableDelayedExpansion
set LF=^


rem Two empty lines are required
set multiLine=This is a!LF!multiline text!LF!line3
echo !multiLine!
