Pulling a Subtree from an existing git

The project has subdirectories sub-1, sub-2, sub-3. The first should be its own repository, but should also retain its own history.

First, we extract its history as an independent item, and make that into a seprate branch.

git subtree split --prefix=sub-1 -b sub

If you want something a few directories deep, you can use `--prefix=sub-1/dir-2/dir-3

Then go and create a new git somewhere else:

cd ..;mkdir sub-1;cd sub-1;git init --bare

Then go back to your initial git repo, and do the following:

git push ../subtest sub:master

Finally, you can clone this repo from your original.

git clone ../subtest
