How to load only the necessary parts of a remote project in Git?

Question

If you work in a large remote repository and want to limit the download to several branches that you work on, how do you configure the git-clone command, assuming that in this case this is the correct command

Answer 1

If you work with two branches in two separate directories, you can configure one of them as a clone of the other:

git clone http://remote/repo.git branch-a
git clone branch-a branch-b

Then attach the remote control originto branch-b:

cd branch-b
git remote add origin http://remote/repo.git

( origin). , , .
