我如何创建一个批处理文件，读取文件，写一个子到另一个文件？ [英] How do I create a batch file that reads a file and writes a substring into another file?

问题描述

我目前有来自一个明确的案例命令，我需要解析导出的文本文件（ output.txt的）。它看起来是这样的：

I currently have an exported text file (output.txt) from a Clear-Case command that I need to parse. It looks like this:

Comparing the following:
  R1.PROD.V1@\VOB_pvob
  R2.PROD.V1@\VOB_pvob
Differences:
>> M:\ACME_PROD\src\ACME@@
>> M:\ACME_PROD\src\ACME\file 2.txt@@
>> M:\ACME_PROD\src\ACME\file 1.txt@@
>> M:\ACME_PROD\src\ACME\file 3.txt@@

我想要做的是使用findstr命令来筛选包含的字符串＆GT;＆GT; 和 @@ 字符串得到看起来像这样（带引号的输出文件如果可能的话：

What I would like to do is use the findstr command to filter the strings that are contained between the ">> " and "@@" strings to get an output file that looks like this (with quotes if possible:

"M:\ACME_PROD\src\ACME"
"M:\ACME_PROD\src\ACME\file 2.txt"
"M:\ACME_PROD\src\ACME\file 1.txt"
"M:\ACME_PROD\src\ACME\file 3.txt"

我是新来编写批处理文件，所以我不知道到底从哪里开始。我设法找到code，它可以通过一个文本文件，以及单独code为findstr命令的行循环，但我会被卡住试图把它放在一起！

I am new to writing batch files and so I don't exactly know where to start. I have managed to find code that can loop through the lines of a text file and separate code for the findstr command, but I get stuck trying to put it all together!

最好的问候，

推荐答案

在这里你去

setlocal enabledelayedexpansion
for /f "skip=1 tokens=* delims=> " %%a in ('"findstr /r [\w^>*] output.txt"') do (
set line=%%a
set line=!line:@=!
echo "!line!" >>new.txt
)

过滤后的字符串将被输出到 new.txt 。
