Git and GitHub concepts: Reviewing updated pull requests locally

Question

I follow the generic OSS structure:

1. the OSS\' remote repository hosted on GitHub
2. a fork of the OSS remote repository to my own remote repository

Answer 1

You can use any of below options to update the PR in local repo.

Option 1: delete the local source branch and recreate to get the update

As you use the commands to get the source branch of the PR locally:

git fetch upstream pull//head:
git checkout 

If the PR is updated (new commits are pushed to the fork repo), you can delete and recreate by:

git checkout master
git branch -D 
git fetch upstream pull//head:
git checkout 

Option 2: add the fork repo as a remote for your local repo

You can add the fork repo as a remote for your local repo by

git remote add fork1  -f

Then you can create a local branch for the PR source branch by

git checkout -b  fork1/

If the PR has been updated, you just need to execute below commands to get the update:

git fetch fork1
git checkout  #If HEAD is not on the 
git reset --hard fork1/
