I faced with a trivial situation but it seems like it have no simple solution: I want to synchronize a single config file between two git repositories. It even could be a one-way interaction: origin is stored in project A and is tracked inside project B

I'm aware of git submodule concept, but submoduling of the large repository in the smaller one only for the sake of a single file seems to be overkill.

You could simply add one repo as a remote and fetch.
Then you can checkout a file from another branch (including a remote tracking one)

git remote add repoA A
git fetch repoA
git checkout repoA/master -- file

(Assuming you want the file from A into repo B)

  • Note that this requires that the path for the file is the same in both repositories. – poke May 25 '15 at 13:26

If both repos are kept on the same machine;

  • Keep the file in the project A repo. There is where its history is recorded.
  • Put a link to the file in project B's repo.
  • Add that link to B's .gitignore.
