不同设备之间的常用文件同步的需要：
经常在一堆电脑和移动设备之间搬运同样的文件，比如歌曲照片，最近常用到的文件；
经常折腾移动设备的人，每个设备各种rom工具和备份；
文件很大很多，网盘受带宽和空间限制，或者不想啥都放网盘；
不勤快的人，不会走哪都带着大移动盘（移动盘和设备之间仍然需要同步）；
不像raid再去提供另一份讲究可靠性的备份存储盘。

这里说的文件目录的同步就是维护这么一大堆常用镜像文件。
这个功能，其实主要就是在一对文件目录结构之间比较异同然后更新到一致。
其实这个功能在下面这些工具里已经重复存在，只是局限在单个应用内：
svn或者git之类的version control工具也可以用来干这个，但是那样会把存储空间时
间浪费在维护文件和目录所有变动过的版本上。
不同设备和OS可能有各自的同步工具，但不通用，或者不是开放所有内容同步。
网盘和本地目录之间的同步，也在做同样的工作。

之前楼上举的那些例子就是比较通用的同步层，只要能把移动或者网络存储map成本地
盘，就可以互相自动更新，不管具体都什么设备，位置和连接。

另外发现有些android手机接windows的时候开始去掉映射成本地盘的disk mount，整出
一个MTP（Media Transfer Protocol）的幺蛾子，

结果大家只好到处找工具把it改回usb mass storage...

https://killer.sh Pre Setup Once you've gained access to your terminal it might be wise to spend ~1 minute to setup your environment. You could set these: alias k = kubectl # will already be pre-configured export do = "--dry-run=client -o yaml" # k get pod x $do export now = "--force --grace-period 0" # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section . Question 1 | Contexts Task weight: 1% You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
