git使用命令切换分支

git一般有很多分支，我们clone到本地的时候一般都是master分支，那么如何切换到其他分支呢？主要命令如下：

1. 查看远程分支

$ git branch -a
我在mxnet根目录下运行以上命令：

<pre class="prettyprint">```bash
~/mxnet$ git branch <span class="hljs-operator">-a
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
  remotes/origin/nnvm
  remotes/origin/piiswrong-patch-<span class="hljs-number">1
  remotes/origin/v0.9rc1</span></span>

可以看到，我们现在在master分支下

**2. 查看本地分支**

```bash
~/mxnet$ git branch
* master
```
```

**3. 切换分支**

```
```
$ git checkout -b v0.9rc1 origin/v0.9rc1
Branch v0.9rc1 set up to track remote branch v0.9rc1 from origin.
Switched to a new branch 'v0.9rc1'

＃已经切换到v0.9rc1分支了
$ git branch
  master
* v0.9rc1

＃切换回master分支
$ git checkout master
Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.
```
```
