【问题描述】：

我在不知不觉中删除了所有重要文件。首先，我使用 git init 初始化我的目录，然后使用 git add 添加文件。之后，为了取消暂存我的文件，我运行了这个命令“git rm -r . -f”，它从我的本地计算机中删除了我的所有文件。

PS C:\Users\ABDUL WAHAB\Desktop\jup> git init
PS C:\Users\ABDUL WAHAB\Desktop\jup> git add .
PS C:\Users\ABDUL WAHAB\Desktop\jup> git status
On branch master

和大家一样做了这件事，然后我做了这个灾难。

谁能帮助我如何恢复这些文件？

【解决方案1】：

您使用git add 添加的任何内容仍将保留在您的存储库中，至少暂时如此。您可以运行 git fsck --lost-found 来查找悬空的对象（即不直接或间接与任何 ref 关联）。

你会得到这样的输出：

dangling blob 83455250c43390ce653e10935b7b5ae743000ff7
dangling commit b35bb2d9ebf399dc6292a99d00cf75a362405815
dangling commit c082520240cc90f93b0c4c4b045e2011652b8b31
dangling blob a08f72e1406444d4e7196562a5894c5a4838c21c

然后，您可以使用git cat-file blob OBJECT_ID 获取其中一个 blob 并查看其内容。如果您想保存它，只需将其重定向到适当命名的文件（例如，git cat-file blob 83455250c43390ce653e10935b7b5ae743000ff7 >weather.txt）。请注意，在这种情况下，非 blob 对您来说可能不是很感兴趣，因此如果您发现其中任何一个，您可以跳过它们。

另外，我可以建议将来为git rm 和git clean 使用-n (--dry-run) 选项吗？至少我发现它很有帮助。
