python脚本多文件搜索查询字符串关键字_使用脚本搜索文件夹里的文件的关键字

当服务器上要搜索某个目录下的所有文件中哪些文件含有某一字符串关键字，可用该脚本。

示例：
在 /usr/local 目录下（包含所有子目录下）的所有可读文件中搜索哪些含有字符串 "if name== "

说明：
1.本脚本只会搜索可读文本文件，list中定义的类型文件会跳过不搜索
2.如果想修改搜索的文件路径和查找文件中的字符串请修改32行的dir和33行的searchWord

脚本如下：

#!/usr/bin/env python
import os

list = ["jar", "zip", "rar", "7z", "tar", "gzip", "gz", "xz", "bz2", "doc", "class", "pak", "webm", "appx",
