populate github fresh repo with old existing stuff

cloneoldbaregitrepo

Create a new repository on GitHub. You'll import your external Git repository to this new repository.

On the command line, make a "bare" clone of the repository using the external clone URL. This creates a full copy of the data, but without a working directory for editing files, and ensures a clean, fresh export of all the old data.

git clone --bare https://githost.org/extuser/repo.git
# Makes a bare clone of the external repository in a local directory
Push the locally cloned repository to GitHub using the "mirror" option, which ensures that all references, such as branches and tags, are copied to the imported repository.

cd *repo.git*
git push --mirror https://github.com/ghuser/repo.git
# Pushes the mirror to the new GitHub repository
Remove the temporary local repository.

cd ..
rm -rf repo.git
