思路

因为本博客是基于Hexo+GitHub-Pages,所以在hexo -d后生成的静态文件都存放于github，所以这是不用担心的。本地的hexo博客的源文件内存放着大量的文章markdown文件,所以问题来了。如果换电脑或者硬件损坏，或者有在其他机器更新文章的需求。就需要做一件事情就是将源文件，也就是本地hexo博客源文件的根目录整个备份。

在那么现在就必须做一些前置操作，就是把你的hexo博客源文件备份到GitHub或者其他代码托管平台，这里的操作就不写出来了，可以参考罪恶的起源，git初识里的如何将代码提交到远程仓库。

也可以使用开源中国的码云,我就是用的码云[手动滑稽]，操作都是一样的。

清除hexo的public目录=>重新生成静态文件=>更新github pages的文章内容=>拉取其他机器的提交=>将所有的文章Markdown源文件改动add到本地暂存=>提交=>push源文件到另一个备份仓库

那么这个命令如何实现，在上一篇文章的额基础上，我对三个命令做出了拓展，使它有一些基本的功能，比如help,防止自己也忘了这个命令干嘛的。加入了只是本地预览博客的指令-s。已经一些友好的提示,让你知道它都做了什么。那么来看看这个命令的脚本长什么样吧！

echo " ==========Over==========="

假设已经将此脚本命名为up.sh

当我输入 sh up.sh时：

$ sh up.sh
        up.sh>>help :
        There is only one parameter: commit-message  or help or -s [locahost server preview Blog]
        After the command, add updates to this blog and submit it to the backup repository!
 ==========Over===========

当我输入sh up.sh help提示和以上一样，所以我是希望能够在每次更新和提交时，能够足够便捷，并且能够提示我填写commit的desc
还有一个指令是-s ，这个指令的作用显而易见只是将hexo的page重新生成并且能够本地预览。获取并不想提交更新，或者只是调试！

当我真正的需要更新文章或者博客的布局，并且备份元数据！
只需要这样写:

1
$ sh up.sh "this is commit message test"

运行如下:

如何多机更新

等你换了电脑或者公司的电脑来更新的的时候。前提是这台电脑是需要有node.js和npm以及hexo环境的。那只需要将备份的元数据clone到你想要的位置。

执行: 

1
$ npm install

然后更新文章，继续使用这个脚本来使得hexo变得更为轻松！

事实证明，这样的方式暂时是没有什么问题的。并且非常的方便！
