如何将git存储库转换为可以应用补丁的单个.diff文件

Question

I have multiple git repositories and would like to generate a big .diff file for each repository.

This .diff patch would then be applied by a customer using something like the 'patch' utility to generate the files in the repository minus git history.

Does anyone know how I would be able to do this?

Thanks for your time, Matt

Answer 1

If you want to diff against nothing...why not just do that?

$ mkdir empty
$ ls
empty myproject
$ diff -ruN empty myproject > diff-against-nothing.patch

git diff 4b825dc642cb6eb9a060e54bf8d69288fbee4904> diff-against-nothing.patch我发现了git的魔法空SHA1！
