github 下fork后如何同步源的新更新内容

给 fork 配置一个 remote

主要使用 git remote -v 查看远程状态。

git remote -v
# origin  https://github.com/YOUR_USERNAME/YOUR_FORK.git (fetch)
# origin  https://github.com/YOUR_USERNAME/YOUR_FORK.git (push)

添加一个将被同步给 fork 远程的上游仓库

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
# 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 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
# 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

更新到 GitHub 的 fork 上
