Git 如何：在分支之间提取差异
我想将两个分支之间的差异文件下载到本地文件夹中。用Git可以吗？
鉴于文件仅添加到源分支，因此它们不会更改。
I would like to download the files that are the difference between two branches into a local folder. Is it possible with Git?
Given the files are only added to the source branch, they are not changed.

您可以通过以下几行获取分支之间的所有更改：
如果您只添加 [text] 文件，那么解析 diff 文件并将其分解为单独的文件将是微不足道的。 （我想说，这是一个不到 50 行代码的 ruby 脚本）
You can get all changes between branches with something around these lines:
If you only add [text] files, then it would be trivial to parse the diff file and break it into individual files. (I'd say, it's a ruby script under 50 lines of code)
假设您现在位于
br2上，并且br1落后于它，括号内的部分 (git diff...) 将给出您在两个头之间更改的文件列表。git archive命令会将这些文件在br2（即当前头）上的文件导出到一个名为export.tar的 tar 文件中。名为exported/的目录。这假设（就像您在问题中所述）您仅添加了新文件并且添加了所有差异。该命令还将导出修改后的文件，但您声称没有任何文件。
Assuming you're on
br2right now andbr1is lagging behind it, the part inside the brackets (git diff...)will give you the list of the files changed between the two heads. Thegit archivecommand will export these files as they are onbr2(i.e. on your current head) to a tar file calledexport.tarinside a directory calledexported/.This assumes (like you stated in your question) that you've only added new files and that all the diffs are adds. The command will also export modified files but you claim not to have any.
