将文本文件过滤到新的文本文件中 [英] Filter a text file into a new text file

问题描述

很抱歉在这里有假人问题.

Sorry about the dummy question here.

在Windows下，我希望能够将一个.txt文件过滤为一个新文件.过滤所有包含特定字符串的行.

Under Windows I would like to be able to filter one .txt file into a new one. Filtering all lines that contain a specific string.

我知道这很容易实现，但是请多多指教.

I know this could well be a really easy one, but would really appreciate a few pointers please.

推荐答案

使用findstr命令:

findstr my-string filename > new-file

findstr /?将为您提供一条用法消息，告诉您如何使用findstr(包括/V开关，如果您想过滤 out 行而不是过滤它们 in .)

findstr /? will give you a usage message telling you how to use findstr (including the /V switch if you wanted to filter lines out rather than filtering them in.)

或者，如果您熟悉grep，并希望在Windows上安装它，请安装 Cygwin . :-)

Or if you're familiar with grep and wishing you had it on Windows, install Cygwin. :-)
