git 提交丢失Warning, you are leaving 2 commits behind,

早上在自己的一个版本代码上编辑，提交commint，但是checkout到其他分支再checkout回来发现该的东西不见了，

幸好terminal还没有关掉，回看日志：

Warning: you are leaving 2 commits behind, not connected to
any of your branches:

****** update
  ****** 增加flask中间服务文件

If you want to keep them by creating a new branch, this may be a good time
to do so with:

git branch <new-branch-name>   ******

然后就将刚刚修改的创建新分支就好，

git branch <new-branch-name>   ******

但是，如果当时终端关闭了或者其他原因没有找到呢？

其实，只要你commint了，git本地是保存了这个变化的，就是没有一个分支链接到这种变化，可以使用：

git reflog show HEAD@{now} -10
****** HEAD@{Fri Jul 27 11:24:56 2018 +0800}: checkout: moving from ******
****** HEAD@{Fri Jul 27 11:19:43 2018 +0800}: checkout: moving from master to 1a
****** HEAD@{Fri Jul 27 11:17:55 2018 +0800}: checkout: moving from develope to master
****** HEAD@{Fri Jul 27 11:17:40 2018 +0800}: checkout: moving from****** to develope
****** HEAD@{Fri Jul 27 11:16:16 2018 +0800}: checkout: moving from master to 1a
****** HEAD@{Fri Jul 27 11:15:50 2018 +0800}: checkout: moving from****** to master
****** HEAD@{Fri Jul 27 11:12:54 2018 +0800}: commit: update
****** HEAD@{Fri Jul 27 10:36:07 2018 +0800}: commit: 增加flask中间服务文件
****** HEAD@{Thu Jul 26 16:34:14 2018 +0800}: checkout: moving from develope to 1a
****** HEAD@{Thu Jul 26 16:34:09 2018 +0800}: commit: update hello.py

然后跟据当时的commit信息找到编号，再

git branch <new-branch-name>   ******

可见，认真写好每个commint 信息是多重要！！！！！
