0x01更新指令

 apt-get clean //清除缓存索引

0x03 更新指令区别（重要）

首先更新命令有：apt-get update ,apt-get upgrade ,apt-get dist-upgrade等三个；

（1）apt-get update:只更新软件包的索引源，作用：同步源的软件包的索引信息，进而进行软件更新；在国内用中科大的源，速度较快，1分钟搞定。

（2）apt-get upgrade:升级系统上安装的所有软件包；若更新失败，所涉及的包会保持更新之前的状态。

（3）apt-get dist-upgrade:升级整个linux系统；例如：从kali linux1.0.1升级到kali linux1.0.2（不仅能够升级所有已安装的软件包，而且会处理升级过程中可能出现的软件冲突。某些情况下，它的部分升级过程需要人工参与）。
