将所有git commit作为一个推送，以清空裸仓库

Question

I have two bare repositories.

repo1 - with all the history
repo2 - new, empty one

I want to push all the files from repo1 to repo2 , but without the whole history, just the the state from the last commit.

I don't want to touch the history of the repo1 (it's best to assume it's read only). In the new repo I don't want to have any history (including reflogs), so shashing after the push is not an option.

Is this ever possible without creating new, temporary repository?
How can I achieve this?

Answer 1

Do the following:

git checkout --orphan temp_branch
git commit -m "initial commit"
git push repo2 temp_branch:master

This will create a temp_branch locally with just a single commit with the current snapshot, and push it to a branch called "master" on repo2.

Answer 2

Assuming that you want to clone the head of master and assuming that you do not insist on a git push :

# in repo2
# git fetch --depth 1 path_to_repo1 master:master
