github同步fork別人的項目到本身的倉庫

github參考說明，英文好的直接看英文吧：

先保證有對fork的項目有一個遠程分支

https://help.github.com/articles/configuring-a-remote-for-a-fork/

完成同步

https://help.github.com/articles/syncing-a-fork/

如下中文版本

當咱們fork一個項目後，在咱們使用代碼的時候就會以咱們本地爲準，不會跟隨咱們fork前的項目，若是須要同步對方的代碼，須要進行同步操做

• 首先咱們先看下遠端現有分支

ipandadeMBP:CMS ipanda$ git remote -v
origin    https://github.com/mpandar/CMS.git (fetch)
origin    https://github.com/mpandar/CMS.git (push)

• 爲fork的項目配置分支

ipandadeMBP:CMS ipanda$ git remote add upstream https://github.com/BootstrapCMS/CMS.git
ipandadeMBP:CMS ipanda$ git remote -v
origin    https://github.com/mpandar/CMS.git (fetch)
origin    https://github.com/mpandar/CMS.git (push)
upstream    https://github.com/BootstrapCMS/CMS.git (fetch)
upstream    https://github.com/BootstrapCMS/CMS.git (push)

• 獲取upstream分支到本地

ipandadeMBP:CMS ipanda$ git fetch upstream
remote: Counting objects: 4, done.
remote: Total 4 (delta 3), reused 3 (delta 3), pack-reused 1
Unpacking objects: 100% (4/4), done.
From https://github.com/BootstrapCMS/CMS
 * [new branch]      0.8        -> upstream/0.8
 * [new branch]      master     -> upstream/master

• 切換到本地master分支

ipandadeMBP:CMS ipanda$ git checkout master

• 同步到主分支

ipandadeMBP:CMS ipanda$ git merge upstream/master

Fast-forward

Ok，即完成同步！
