现在假设你添加了一个新文件a.txt，内容如下：

An a file

然后git add a.txt，git reset --hard，恢复到初始状态。

这时运行git fsck的结果如下：

Checking object directories: 100% (256/256), done.
dangling blob 751b0aae0e88fc095ff05e3b697402f5721d3ae6

751b0aae0e88fc095ff05e3b697402f5721d3ae6就是a.txt经过 hash 以后的值，查看内容可以使用

~ > git cat-file -p 751b0aae0e88fc095ff05e3b697402f5721d3ae6
An a file

大致原理就是这样，--lost-found选项就是自动把a.txt输出到.git/lost-found/other下，以751b0aae0e88fc095ff05e3b697402f5721d3ae6的文件名存在。文件名信息确实真的恢复不回来，这个没办法。
