Complete Git Guide: Understand and Master Git and GitHub - Fetching Changes from Upstream

The video tutorial explains the concept of remote repositories in Git, focusing on 'origin' and 'upstream'. It demonstrates how to fetch changes from an upstream repository using the 'git fetch' command and view the fetched branches. The tutorial also covers actions that can be performed with these branches, such as checking out and merging them into local branches. Finally, it introduces the concept of syncing changes from the upstream master branch to the local master branch, which will be detailed in the next lecture.

What is the role of the 'origin' remote in a Git repository?

• It is used to fetch changes from upstream.

• It points to the forked repository.

• It points to the parent repository.

• It is a local branch.

Which command is used to list all branches, including remote ones?

• git branch -r

• git branch -d

• git branch -a

• git branch -m

What does the 'git fetch' command do?

• It merges changes from the remote repository.

• It creates a new branch in the local repository.

• It deletes branches from the remote repository.

• It updates local references to remote branches.

What is the effect of the 'git fetch' command on the working directory?

• It stages all changes in the working directory.

• It deletes untracked files in the working directory.

• It leaves the working directory unchanged.

• It updates the working directory with remote changes.

What is the next step after fetching changes if you want to sync them to your local branch?

• Use 'git reset' to discard changes.

• Use 'git merge' to integrate changes.

• Use 'git push' to send changes to the remote.

• Use 'git commit' to apply changes.
