Python写的系统常用命令

python写的系统常用命令，linux和windows通用，用的时候直接from util import *导入即可使用，很方便，本来是一个脚本，分成两部分发了。

#!/usr/bin/python
# -*- coding: utf-8 -*-
# 通用功能类封装

sed封装，根据传入的type参数执行相应操作，type可以为以下几种：

i 在s_str行前面插入d_str，若s_str为空，则默认在文件头部插入；
d 删除s_str所在行；
s 将s_str替换为d_str。
type及file_name为必需的参数。
例子：
替换字符串：sed("s", "/etc/test.txt", "abc", "123")
