At this point the repository has all the commits from the original repository, but they are not integrated into the cloned repository’s local branches.

Find the “Changed README in original repo” commit in the history above. Notice that the commit includes “origin/main” and “origin/HEAD”.

Now look at the “Updated Rakefile” commit. You will see that the local main branch points to this commit, not to the new commit that we just fetched.

The upshot of this is that the “git fetch” command will fetch new commits from the remote repository, but it will not merge these commits into the local branches.

Check the README

We can demonstrate that the cloned README is unchanged.




$ cat README
This is the Hello World example from the git tutorial.

See, no changes.
