如何在Windows批处理文件中嵌入文本文件 [英] How to embed a text file in a Windows batch file

问题描述

我需要创建一个写入文本文件(可能包括变量)的批处理文件.在带有bash的Unix中，这很简单:

I need to create a batch file that writes a text file (possibly including variables). In Unix with bash this is trivial:

#!/bin/bash
ver="1.2.3"
cat > file.txt <<EOL
line 1, ${ver}
line 2 
line 3
... 
EOL

使用批处理文件最简单的方法是什么?

What is the simplest way to do this with a batch file?

注意:在Windows批处理中，使用 heredoc的"heredoc"例程是否有完整的解决方案?

，但对于临时使用而言似乎太复杂了.我正在寻找一种快速简单的方法.

Note: there is a complete solution using an 'heredoc' routine at heredoc for Windows batch? but it seems too complex for ad-hoc use. I'm looking for a quick and simple way.

推荐答案

如果只有一个数据块(文本)，则跟踪效果很好

The follwoing works fine, if there is just one block of data (text)

@ECHO OFF
set string=beautyful
REM get linenumber for Data:
for /f "tokens=1 delims=:" %%a in ('findstr /n /b "REM StartData" "%~f0"') do set ln=%%a

REM print Data (use call to parse the line and evaluate variables):
(for /f "usebackq skip=%ln% delims=" %%a in ("%~f0") do call echo %%a)>"new.txt"
type "new.txt"
goto :eof

REM StartData
hello %string% world
line 2
line 3

如果数据中没有变量，请省略call.优势:无需逃脱任何东西.即使通常是有毒字符也可以工作(代替for循环，也可以只使用more +%ln% "%~f0").可悲的是，当您使用call解析行以获取变量时，您失去了这一优势.

If you don't have variables in the data, omit the call. Advantage: no need to escape anything. Even usually poisonous characters work (instead of the for loop, you can also just use more +%ln% "%~f0"). Sadly, you loose this advantage, when you use call to parse the lines for variables.
