The following example uses IBM/Drain3 on Github as an example

Fork the target repository and clone it locally

$ git clone https://github.com/ieven/Drain3.git

Copy the code
$ cd Drain3/
Copy the code

Run git remote -v to check the path to your remote repository

iEven@DESKTOP-OG5S6BE MINGW64 /d/try/Drain3 (master)
$ git remote -v
origin  https://github.com/ieven/Drain3.git (fetch)
origin  https://github.com/ieven/Drain3.git (push)
Copy the code

If only the above 2 lines indicate you have not set upstream. If so, skip the create upstream step below.

Create the upstream

iEven@DESKTOP-OG5S6BE MINGW64 /d/try/Drain3 (master)
$ git remote add upstreamhttps://github.com/IBM/Drain3.git
iEven@DESKTOP-OG5S6BE MINGW64 /d/try/Drain3 (master)
$ git remote -v
origin  https://github.com/ieven/Drain3.git (fetch)
origin  https://github.com/ieven/Drain3.git (push)
upstream        https://github.com/IBM/Drain3.git (fetch)
upstream        https://github.com/IBM/Drain3.git (push)
Copy the code

Git remote -v git remote -v git remote -v

Get updates from upstream

Run git fetch upstream to fetch the Drain3 repository update.

iEven@DESKTOP-OG5S6BE MINGW64 /d/try/Drain3 (master)
$Git fetch upstream automatically synchronizes repository updatesCopy the code

Merge into the master branch of the local repository

iEven@DESKTOP-OG5S6BE MINGW64 /d/try/Drain3 (master)
$Git checkout master iEven@DESKTOP-OG5S6BE MINGW64 /d/try/Drain3 (master)
$Git merge upstream/masterCopy the code

Push to its own remote repository

Git push pushes changes from the local repository to the Github repository (which you fork to yourself). Note that there are no additional arguments after Git push.

iEven@DESKTOP-OG5S6BE MINGW64 /d/try/Drain3 (master)
$Git push: Enter your password for git pushCopy the code

At this point your fork repository update is complete
