從遠(yuǎn)程分支 checkout 出來的本地分支吏奸，稱為_跟蹤分支(tracking branch)_。跟蹤分支是一種和遠(yuǎn)程分支有直接聯(lián)系的本地分支导帝。在跟蹤分支里輸入Git push地消，Git 會自行推斷應(yīng)該向哪個服務(wù)器的哪個分支推送數(shù)據(jù)废赞。反過來虎眨，在這些分支里運(yùn)行g(shù)it pull 會獲取所有遠(yuǎn)程索引弟劲，并把它們的數(shù)據(jù)都合并到本地分支中來祷安。在克隆倉庫時，Git 通常會自動創(chuàng)建一個名為 master 的分支來跟蹤 origin/master兔乞。這正是git push 和 git pull 一開始就能正常工作的原因汇鞭。當(dāng)然，你可以隨心所欲地設(shè)定為其它跟蹤分支庸追，比如origin 上除了 master 之外的其它分支霍骄。剛才我們已經(jīng)看到了這樣的一個例子：git checkout -b [分支名] [遠(yuǎn)程名]/[分支名]。[plain] view plain copyshuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (master)? $ git checkout --track origin/br-2.1.2.1?
