git删除了所有内容，如何恢复文件和文件夹 [英] git deleted everything, how to recover files and folders

问题描述

这是我第一次使用git，我想将一个现有的项目导入到github中，并且一切都被删除了。搜索答案后，我认为git删除后，git拉文件，我试图恢复文件和文件夹，但我找不到如何做到这一点。

我做了下一个：

但是，如何恢复包含所有文件和文件夹的目录？现在我正在使用.git文件夹的副本来避免另一个问题。

摇晃树木的物体，你很好。以下内容应该可以工作：首先将悬挂树恢复为Git的索引：

  git read-tree bfe11a30d57a0233d3b0c840a3b66f6421987304 
  

接下来，从现在恢复的索引中更新您的工作目录：

  git checkout-index -a 
  

It was the first time that I was using git, I wanted to import an existing project into github and everything was deleted. After search for an answer I think git deleted the files after git pull, I'm trying to recover the files and folders but I can't find how to do it.

I did exactly the next:

jesus@jesus-K52F:~/Escritorio/Django/Ujixy$ git init

jesus@jesus-K52F:~/Escritorio/Django/Ujixy$ git add .

But, How can I recover the directories with all the files and folder? Now I'm working in a copy of .git folder to avoid another problems.

解决方案

As you already have a reference to a dangling tree object, you're well on your way. The following should work: first recover the dangling tree into Git's index:

git read-tree bfe11a30d57a0233d3b0c840a3b66f6421987304

Next, update your working directory from the now-recovered index:

git checkout-index -a
