1 场景
今天内网下载一个红帽的ISO文件
wget http://www.cmdschool.org/rhel-server-5.2-x86_64/rhel-5.2-server-x86_64-dvd.iso
结果下载到68%出错，下载程序另起了一个文件，详细如下（注意第6与16行）：

2 解决方案
试想能不能把文件合成，于是尝试如下操作：
cat rhel-5.2-server-x86_64-dvd.iso.1 >> rhel-5.2-server-x86_64-dvd.iso
通过对比服务器上源文件的MD5
md5sum rhel-5.2-server-x86_64-dvd.iso
显示一样的值：
5390f9f703e083cf1470fb438ea49082 rhel-5.2-server-x86_64-dvd.iso
注：这意味着文件可以这样合成并且可用，太让我高兴了。O(∩_∩)O哈哈~
