在最初意外删除所有文件的恐慌之后，我使用以下方法来取回我的数据

git reset HEAD@{1}         
git fsck --lost-found      
git show 
git revert <sha that deleted the files>

如果你不喜欢“还原还原”这个想法(特别是当这意味着丢失多次提交的历史信息时)，你可以随时查看git文档中关于“还原错误合并”的内容。

给定下面的起始情况

 P---o---o---M---x---x---W---x
  \         /
   A---B---C----------------D---E   <-- fixed-up topic branch

(W是归并M的初始还原;D和E修复了你最初损坏的特性分支/提交)

你现在可以简单地重放提交A到E，这样它们都不“属于”被还原的合并:

$ git checkout E
$ git rebase --no-ff P

分支的新副本现在可以再次合并到主分支:

   A'---B'---C'------------D'---E'  <-- recreated topic branch
  /
 P---o---o---M---x---x---W---x
  \         /
   A---B---C----------------D---E

要返回在提交后恢复的非暂存和暂存更改:

git reset HEAD@{1}

恢复所有未执行的删除操作:

git ls-files -d | xargs git checkout --

I saw responses include the command git reset --hard HEAD without any caution. You should be careful with that command because of the option --hard. It resets your index and your remote repo but mostly, it also resets your local repo and all commits that were not pushed to the remote yet will be lost, both from your local repo and index. Never use that flag --hard unless you are sure you also want to reset all your local work from the current commit till the hash you chose. If anyway you did it by mistake, run git reflog to retrieve your ~hash then git reset --hard ~hash to recover your files.

在我的例子中，我需要在恢复后提交更改，然后才能在没有失败的情况下选择原始提交。

git commit -m "Make changes (original commit)."
git revert <original commit hash>
git commit -m "Revert original commit."
git cherry-pick <original commit hash>

如果你还没有按这个改变，git重置-硬头^

否则，还原还原完全没问题。

另一种方法是git结帐HEAD^^——。然后git add -A && git提交。
