# 第四堂課 - git rebase

*rebasing*是 merge branch 的第二種方法。rebasing 就是取出一連串的 commit，"複製"它們，然後把它們接在別的地方。

雖然聽起來難以理解，rebasing 的優點是可以建立更線性的 commit history。假如只允許使用 rebasing 的話，則我們的 repo 中的 commit log 或者是 commit history 會更加簡潔好看。

讓我們親身體會一下...

## 破關提示：

想完成這一關，執行以下操作：

* 建立`bugFix`branch
* commit 一次
* 切換回 master branch 再 commit 一次
* 再次切換到 bugFix branch，接著 rebase bugFix 這個 branch 到 master branch 上

祝你好運啦！

## 語法如下：

```
git branch bugFix
git checkout bugFix
git commit
git checkout master
git commit
git checkout bugFix
git rebase master
```
