迁移git lfs后，git repo崩溃了

Question

不正确使用git lfs migrate --everything 不知为何，生成了一个包含所有已知文件类型的.gitattributes文件。 这基本上毁了我们的项目，因为所有类型的文件现在看起来都是这样的。

    version https://git-lfs.github.com/spec/v1
    oid sha256:f6d1237f5b00a49b32cca659d9764fc16cf012ea887c3007bf9a2120d7e9fef4
    size 792

...在整个repo历史中 包含的目录仍然是大致相同的文件大小，这给我带来了希望，有一种方法可以恢复，但我自己还没能解决。

由于不寻常的情况，这个repo还没有在github上--有一个repo的副本，如果需要的话，我们可以恢复到这个副本，但这意味着要损失几天的工作。

有什么办法可以撤销lfs命令吗？

这就是.gitattributes文件不知为何被生成的原因。

仍然不完全清楚这是怎么发生的，但通过简单地运行以下命令来解决这个问题git lfs checkout

把这个留在这里，因为其他人在网上搜索的时候，就会发现一大堆未解决的线程。
