Complete Git Guide: Understand and Master Git and GitHub - Section 16 Introduction

The video tutorial explains the behavior of branches and commits in version control systems. It covers how the head pointer changes when checking out branches and what happens when you check out a specific commit, leading to a detached head state. The tutorial also discusses making experimental commits in this state and how to retain them by creating a new branch.

What happens to the branch pointer when you make a new commit?

• It stays at the initial commit.

• It gets deleted.

• It points to the HEAD.

• It moves to the new commit.

In a detached HEAD state, what does the HEAD point to?

• A specific branch

• A specific commit

• The latest commit

• The initial commit

What is a potential risk of leaving experimental commits in a detached HEAD state?

• They will be converted to branches.

• They will be automatically merged.

• They will be garbage collected.

• They will be pushed to the remote repository.

How can you preserve experimental commits made in a detached HEAD state?

• By creating a new branch from the detached HEAD state

• By merging them into the main branch

• By pushing them to a remote repository

• By deleting the HEAD

What warning might you receive if you try to leave a detached HEAD state without preserving commits?

• A warning about branch deletion

• A warning about merge conflicts

• A warning about potential garbage collection

• A warning about uncommitted changes
