1、安装git，安装bash的方式安装。会将linux相关的小命令都安装成功
2、然后可以打开git bashcd到相应的目录，就可以使用find/grep等命令了。
3、举例：red@redmark MINGW32 /c/android/firewall$ find | xargs grep "iptables"grep: .: Is a directorygrep: ./afwall-beta: Is a directorygrep: ./afwall-beta/aFWall: Is a directorygrep: ./afwall-beta/aFWall/src: Is a directorygrep: ./afwall-beta/aFWall/src/main: Is a directorygrep: ./afwall-beta/aFWall/src/main/assets: Is a directorygrep: ./afwall-beta/aFWall/src/main/java: Is a directory
