# 33. 重置 master 分支 ## 目的 > 重置 master 分支到沖突提交前的地方。 ### 重置 master 分支 當我們添加交互模式到 master 分支時，我們所做的更改與 greet 分支中的更改沖突了。讓我們倒回 master 分支中沖突更改前的地 方。這允許我們來演示變基命令而不必擔心沖突。 ``` $ git checkout master $ git hist ``` ``` $ git hist * 05f32c0 2013-04-13 | Made interactive (HEAD, master) [Jim Weirich] * b59a8c2 2013-04-13 | Added README [Jim Weirich] * 96ee164 2013-04-13 | Added a Rakefile.
