updating a fork from git code example
Example 1: update fork repository
## Add Original Repository
git remote add upstream https://github.com/OriginalOwner/OriginalProject.git
## Verify if Repository is added
git remote -v
## Fetch Updates from Original Repository
git fetch upstream
## Checkout to your master branch
git checkout master
## Get Updates from upstream repo
git merge upstream/master
## Push the commit over
git push origin master
Example 2: update my fork repository at github
# Add the remote, call it "upstream":
git remote add upstream https://github.com/whoever/whatever.git
# Fetch all the branches of that remote into remote-tracking branches,
# such as upstream/master:
git fetch upstream
# Make sure that you're on your master branch:
git checkout master
# Rewrite your master branch so that any commits of yours that
# aren't already in upstream/master are replayed on top of that
# other branch:
git rebase upstream/master
