Given a branch foo and a remote upstream:

As of Git 1.8.0:

git branch -u upstream/foo

Or, if local branch foo is not the current branch:

git branch -u upstream/foo foo

Or, if you like to type longer commands, these are equivalent to the above two:

git branch --set-upstream-to=upstream/foogit branch --set-upstream-to=upstream/foo foo

As of Git 1.7.0:

git branch --set-upstream foo upstream/foo

Notes:

All of the above commands will cause local branch foo to track remote branch foo from remote upstream. The old (1.7.x) syntax is deprecated in favor of the new (1.8+) syntax. The new syntax is intended to be more intuitive and easier to remember.

 

 

 

官方文档：git-branch(1) Manual Page

-u <upstream>

--set-upstream-to=<upstream>

Set up <branchname>'s tracking information

so <upstream> is considered <branchname>'s upstream branch.

If no <branchname> is specified, then it defaults to the current branch.

 

假定，需要把foo分支，和远端的foo分支进行映射，远端名称为upstream

如果当foo分支不是当前分支，使用如下命令

git branch -u upstream/foo foo

如果foo分支是当前分支

git branch -u upstream/foo

在checkout分支的时候，就进行映射

Tracking Branches

Checking out a local branch from a remote branch automatically creates what is called a tracking branch. Tracking branches are local branches that have a direct relationship to a remote branch. If you’re on a tracking branch and type git push, Git automatically knows which server and branch to push to. Also, running git pull while on one of these branches fetches all the remote references and then automatically merges in the corresponding remote branch.

When you clone a repository, it generally automatically creates a master branch that tracks origin/master. That’s why git push and git pull work out of the box with no other arguments. However, you can set up other tracking branches if you wish — ones that don’t track branches on origin and don’t track the master branch. The simple case is the example you just saw, running git checkout -b [branch] [remotename]/[branch]. If you have Git version 1.6.2 or later, you can also use the --track shorthand:

$ git checkout --track origin/serverfixBranch serverfix set up to track remote branch refs/remotes/origin/serverfix.Switched to a new branch "serverfix"

To set up a local branch with a different name than the remote branch, you can easily use the first version with a different local branch name:

$ git checkout -b sf origin/serverfixBranch sf set up to track remote branch refs/remotes/origin/serverfix.Switched to a new branch "sf"

Now, your local branch sf will automatically push to and pull from origin/serverfix.

$ git branch -vv

发现chucklu_zhCN分支没有和远端建立映射关系

 

添加映射

Administrator@LuJunTao MINGW64 /d/SourceCode/GameSourceCode/Hearthstone-Deck-Tracker (chucklu_zhCN)

$ git branch -u chucklu/chucklu_zhCN

Branch chucklu_zhCN set up to track remote branch chucklu_zhCN from chucklu.

 

再次查看映射

remove the remote tracking branch

To remove the upstream for the current branch do:

$ git branch --unset-upstream

This is available for Git v.1.8.0 or newer.
