更新压缩包
一段时间之后，需要将一些新文件添加到文件夹中，并且希望将他们添加到压缩包里面，可以不用创建一个新的压缩包，只需要更新现有的压缩包就可以。
首先将test目录压缩
[root @localhosttest]# 7z a files.7z test/

在test文件夹中创建几个文件，然后再更新压缩包：
[root @localhosttest]# touch test/file{ 5.. 10}.txt
[root @localhosttest]# 7z u files.7z test/

查看一下是否已经添加文件。
[root @localhosttest]# 7z l files.7z
