在批处理中用新行替换字符串 [英] Replace string with a new line in Batch

问题描述

set NLM=^


set NL=^^^%NLM%%NLM%^%NLM%%NLM%
SET memoli=%token:QMZ=%NL%%%
echo %memoli%>>%tmp%\list2.txt

我不能用新行更改字符串"QMZ".该怎么做?

I cant change the string "QMZ" with a new line. How to do that?

推荐答案

非常简单

setlocal EnableDelayedExpansion
set "token=HelloQMZworld"
echo !token:QMZ=^

!

它用作批处理解析器首先解析多行插入符，然后将其替换为单个换行符.
然后，在延迟扩展阶段，它将QMZ替换为单个换行符，这在该阶段是合法的.

It works as the batch parser parses first the multiline caret and replace it with a single linefeed.
Then in the delayed expansion phase it replaces the QMZ with a single linefeed, which is legal in that phase.

要使用替换后的字符串设置新变量，只需使用

To set a new variable with the replaced string simply use

setlocal EnableDelayedExpansion
set "token=HelloQMZworld"
set newVal=!token:QMZ=^

!
echo !newVal!
