First add other people’s repositories to your upstream remote, usually named upstream. Just do it once.

git remote add upstream  原作者仓库地址

At this time, use git remote -v to see that one origin belongs to you and the other upstream belongs to the original author.

Secondly update the code

Use git fetch upstream to pull the original author’s repository for updates.

Use git checkout master to switch to your own master

Use git merge upstream/master, merge or rebase to your master

If the forked code in your warehouse has not been modified since the last time it was merged, then I recommend directly deleting the project in your warehouse and then forking it again.

I personally don’t like the merge method mentioned above -- the history record of the merge method is not very nice.

If you don’t want to delete and re-fork, you can directly:

git checkout master
git remote add upstream 别人的代码库地址
git fetch upstream/master
git reset --hard upstream/master

First add the address of the library you forked

git remote add FORK-sync https://github.com/xxx/yyy.git
git remote -v

You can see similar ones

FORK-sync    https://github.com/xxx/yyy.git (fetch)
FORK-sync    https://github.com/xxx/yyy.git (push)
origin    git@github.xxx/born-1.git (fetch)
origin    git@github.xxx/born-1.git (push)

Then accept the contents of the forked library

git fetch FORK-sync

Merge

git merge FORK-sync/master

Just push it to your remote warehouse

git push

cd YOUR-FORKED-REPO
git fetch upstream
git checkout master
git merge upstream/master
