Introduction
目标:在github上fork了其他用户的仓库,当原作者更新仓库后,让自己fork的仓库与原仓库保持一致。
名词含义:
fork仓库(YOUR_FORK):你fork到自己github账户的仓库
原始仓库(ORIGINAL_REPOSITORY): 其他用户的原始仓库
Configuring a remote for a fork
为了能fork仓库能与原始仓库同步,我们必须先为fork仓库配置新的remote(原始仓库)
- 打开终端,进入本地项目目录
- 列出fork仓库当前配置的远程仓库。
git remote -v
$ git remote -v #查看远程状态
> origin https://github.com/YOUR_USERNAME/YOUR_FORK.git (fetch)
> origin https://github.com/YOUR_USERNAME/YOUR_FORK.git (push)
- 为fork仓库指定一个新的远程仓库upstream,即你要同步的原始仓库。
$ git remote add upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git
- 再次查看状态确认是否配置成功。
$ git remote -v
> origin https://github.com/YOUR_USERNAME/YOUR_FORK.git (fetch)
> origin https://github.com/YOUR_USERNAME/YOUR_FORK.git (push)
> upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git (fetch)
> upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git (push)
Syncing a fork
- 从上游仓库 fetch 分支和提交点,传送到本地,并会被存储在一个本地分支upstream/master.
git fetch upstream
$ git fetch upstream
> remote: Counting objects: 75, done.
> remote: Compressing objects: 100% (53/53), done.
> remote: Total 62 (delta 27), reused 44 (delta 9)
> Unpacking objects: 100% (62/62), done.
> From https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY
> * [new branch] master -> upstream/master
- 切换到本地主分支(如果不在的话).
git checkout mster
$ git checkout master
> Switched to branch 'master'
- 把 upstream/master 分支合并到本地 master 上,这样就完成了同步,并且不会丢掉本地修改的内容。
git merge upstream/master
$ git merge upstream/master
> Updating a422352..5fdff0f
> Fast-forward
> README | 9 -------
> README.md | 7 ++++++
> 2 files changed, 7 insertions(+), 9 deletions(-)
> delete mode 100644 README
> create mode 100644 README.md
- 如果想更新到 GitHub 的 fork 上,直接
git push origin master
就好了。
