#! /bin/bash
#功能:本段脚本实现了两类功能(1)文件的批量创建和(2)文件的批量改名操作,可用于相片的整理过程
# 并且具有良好的扩展性,可以添加自己的选项实现所需功能。
#试用平台:ubuntu 12.04,理论上现在版本的linux都可用
#llt 2014.03.17
#功能:指定文件夹下文件批量创建
#用法:./ChangeName.sh -t 文件夹路径 创建文件个数 创建文件前缀

#功能:指定文件夹下所有普通文件文件全部重命名
#用法:./ChangeName.sh -c 文件夹路径 重命名前缀

#学到知识:1、getopts命令的使用;2、shell中整形变量的声明与算术运算;3、shell中while,for,if,case等条件控制指令的使用;4、shell中函数的使用及参数传递;5、shell中特殊变量$@,$?,$#,$[1-9]使用
