搜索然后删除，取决于文件是否包含字符串 [英] Search and then delete depending on whether files contain a string

问题描述

我想在单个目录中搜索一个字符串（'monkey'）的多个文本文件，如果字符串存在的话，取决于哪个最简单：

1. 重命名匹配的字符串 - 例如改变猴子monkey1然后保存文件并进行搜索/处理
   
   $ b $或$
   
   ol start =2>
   
2. 删除任何具有匹配字符串的文件。
   

使用本地Windows批处理命令修改文本文件的内容是相当复杂的，所以我们可以使用本地Windows批处理命令来修改文本内容。选项1）并不容易。如果你下载第三方工具，比如gnu sed for Windows，很容易。

选项2）非常简单。你可以在没有批处理文件的情况下在命令行上执行它。假设您的当前目录是您要查找文件的位置：

  for / feol =：delims =％F in（'findstr / m monkey * .txt'）do del％F
  

在批处理文件中，你需要将百分比加倍 - 使用 %% F 而不是％F p>

FINDSTR命令有许多选项，例如/ I用于不区分大小写的搜索，/ S用于搜索子目录，和/ R用于原始正则表达式搜索。 b $ b

I'd like to search through multiple text files in a single directory for a string ('monkey'), if the string exists, then either, depending on what's easiest:

1. rename the matching string - e.g. change monkey monkey1 and save then file and carry on searching/processing

or

2. Delete any file that has the matching string.

Have searched but can't seem to find anything straightforward.

解决方案

Modifying the contents of a text file is fairly complex using native Windows batch commands, so option 1) is not easy. Though it is easy if you download a 3rd party tool like gnu sed for Windows.

Option 2) is very easy. You can do it on the command line without a batch file. Assuming your current directory is where you want to look for the files:

for /f "eol=: delims=" %F in ('findstr /m monkey *.txt') do del "%F"

If executed from within a batch file then you need to double up the percents - use %%F instead of %F.

There are many options to the FINDSTR command, such as /I for case insensitive search, /S to search subdirectories, and /R for primitive regex searches.
