git - git 保留历史中的文件，其他人已删除

Question

我按照这个http://help.github.com/remove-sensitive-data/

但仍有一些文件难以删除，我只需要保留/lib/request.js /lib/response.js在 git://github.com/visionmedia/express.git 中，其他文件应该全部删除。

在那篇文章中，我需要告诉要删除哪个文件，例如 Rakefile

git filter-branch --index-filter 'git rm --cached --ignore-unmatch Rakefile' --prune-empty -- --all

但我想要的是告诉要保留哪个文件。

我怎样才能做到这一点？

您确定您不应该创建一个全新的存储库并从复制的这两个文件开始吗？

$ cd my_repo/
$ git init

    Add request, response from Express.

请注意，即使这样也可能无法满足您的要求；两者都request.js依赖response.js于，例如util.js在同一目录中找到。您可能只想添加 Express 作为项目的依赖项。
