Git obtains the remote branch locally and establishes the association track

From Remote BranchCheckoutThe local branch is called _ tracking branch )_. A trace branch is a local branch that is directly associated with a remote branch. EnterGit push, Git will automatically infer which branch of the server to which data should be pushed. In turn, run in these branchesGit
PullAll remote indexes are obtained and their data is merged into the local branch.

When cloning a repository, git usually automatically createsMasterTo trackORIGIN/Master. This is exactlyGit pushAndGit pullThe reason for normal operation at the beginning. Of course, you can set it to another tracking branch as you like, suchOriginExceptMasterOther branches. We have seen an example like this:Git
Checkout-B [branch name] [remote name]/[branch name].

Delete the branch of the track.

Use the checkout command to create a new branch br-2.1.2.1 that tracks remote origin/br-2.1.2.1
