Complete Git Guide: Understand and Master Git and GitHub - What is FETCH_HEAD?

This video tutorial covers the basics of managing branches in Git, including verifying remote and local branches, using git fetch and pull commands, and understanding the fetch head file. It explains how to check for updates and verify commits using SHA-1 hashes, ensuring that local branches are in sync with remote branches. The tutorial also demonstrates how Git compares changes between branches and the role of the fetch head file in this process.

What command is used to list all branches, both remote and local, in a Git repository?

• git branch -l

• git branch -v

• git branch -r

• git branch -a

What does the 'git fetch' command do?

• It deletes branches that are no longer needed.

• It updates the local repository with changes from the remote repository without merging.

• It creates a new branch in the local repository.

• It merges changes from the remote branch into the local branch.

What is the primary function of the 'git pull' command?

• To delete the local branch.

• To fetch updates and then merge them into the local branch if there are changes.

• To only merge changes from the remote branch into the local branch.

• To only fetch updates from the remote repository.

What happens if there are no changes in the remote branch when you perform a 'git pull'?

• The remote branch is merged into the local branch.

• The local branch is deleted.

• A new branch is created.

• Git reports that the branch is already up to date.

What file does Git use to track the last commit in the remote repository?

• FETCH_HEAD file

• COMMIT_LOG file

• BRANCH_INFO file

• HEAD file

What information does each line in the FETCH_HEAD file contain?

• The URL of the remote repository and the date of the last fetch.

• The SHA-1 hash of the last commit and the name of the remote branch.

• The name of the local branch and its last commit message.

• The list of all local branches and their statuses.

How does Git determine if the local branch is in sync with the remote branch?

• By comparing the branch names.

• By checking the number of commits.

• By comparing the SHA-1 hashes of the last commits.

• By verifying the branch creation dates.
