the shell using lists and dictionaries realization of multi-file decompression

Depending on the work you want to extract the files to a different folder, so write a script deal with these things

1. Preparations

First, to have a unified naming format, this is a prerequisite to write the script, or just a bunch of strange names package deal you enough headaches
following naming format: in line with a similar format to

v6.1_aiwobu.zip
v6.2_aiwobu.zip
v6.1_buaini.zip

2. write the script

Knowledge Point 2.1 used

1. Generating a list of operation
2. Dictionary generating operation
3. Biography participate function's return value
4. Other basics: sed, awk, etc.

2.2 detailed script

#!/bin/bash
#用途:	1.根据文件名解压拷贝web文件到指定位置，并更改版本号
#		2.解压服务文件到指定位置
#原理：	1.分别获取版本号,存储在列表中
#		2.将列表生成字典,方便取用
