git fsck 恢复误删 stash 贮藏的数据

问题：

stash 之后的内容没有应用到代码上就直接给删除了。如何恢复代码？

首先，执行：

git fsck --lost-found
1

执行完之后会得到很多 id ，其中会标明哪个是 commit

Checking object directories: 100% (256/256), done.
Checking objects: 100% (64354/64354), done.

可以通过 git show 来查看是否是自己想要的代码，排列顺序是最新的在最上面。

git show + id
1

找到想要的代码 id 后，执行 git merge 来恢复代码

git merge + id
