图 8-8：开发周期中的多个分支
希望你开动脑筋，思考一下分支所带来的可能性。
•
如果你有新的尝试，同时又不想影响
master
分支
，就可以创建一个新分支。如果尝试
不成功，那么也无妨——
master
分支的内容不会受到任何影响。
•
分支形成了你与其他作者在同一仓库上协作的基础。如果你工作在分支
A
，你的同事工
作在分支
B
，那么你就可以放心
，你们不会影响到彼此。（现在，当你
合并
两个分支的
变更时，可能会遇到一些问题，但这就是另一回事了。
8.6.3
节将解决这些问题。
）
现在把注意力转向
Git
分支实战，看看如何将理论应用于实践。
8.6.1
创建分支
要创建
Git
分支（还是那句话，分支只是提交的引用），可以使用
git branch
命令。所以，
只需简单地执行
git branch testing
就能创建出上一节中讨论的
testing
分支。该命令不会
产生任何输出，不过还是有办法验证它究竟做了什么。
首先，在
.git/refs/heads
目录中查找
，你会发现一个以新分支为名的文件。如果对该文件执
行
cat
，则会看到它指向创建新分支时由
HEAD
引用的提交。来动手验证一下。
