How to synchronize with the original warehouse after the GitHub is Fork (ii) __github

We have previously in the "GitHub fork after how to sync with the original warehouse," this blog details how to sync with the original warehouse project issues, look at the actual operation of the process or slightly cumbersome, in fact, there is a more convenient than the previous blog to optimize the method, so that we realize the function.
First three steps, please refer directly to "GitHub fork after how to sync with the original warehouse" (1) (2) (3). The operation is exactly the same. Then execute the following command directly:
Git pull upstream Master
That is, directly from the original warehouse master branch to pull the substitution code and directly merge the code, which pull=fetch+merge. So the original two-step operation here we are directly merged into one step operation, the logic is simpler.
After completing the above steps, the local warehouse has been synchronized with the original warehouse, then the local changes need to be synchronized to their GitHub warehouse to execute the following command:
Git push Origin Master
That is, the modification of the local master branch is pushed to the master branch of GitHub.       After the steps above, your own GitHub fork warehouse has been synchronized with the original project. The above operation is not limited to the master branch, you can switch any branch:
Switch to local branch:
git checkout local branch name

To check out a remote branch:
git checkout local branch name origin/remote Branch Name
