lab 42 Fetching Changes
- Learn how to pull changes from a remote repository.
cd ../cloned_hello git fetch git hist --all
NOTE: Now in the cloned_hello repo
$ git fetch From /Users/jim/Downloads/git_tutorial/work/hello e0cc19e..b39ac69 master -> origin/master $ git hist --all * b39ac69 2020-06-20 | Changed README in original repo (origin/master, origin/HEAD) [Jim Weirich] * e0cc19e 2020-06-20 | Updated Rakefile (HEAD -> master, origin/greet) [Jim Weirich] * 046088a 2020-06-20 | Hello uses Greeter [Jim Weirich] * 3db0ffe 2020-06-20 | Added greeter class [Jim Weirich] * 8d90176 2020-06-20 | Added README [Jim Weirich] * 5aec14d 2020-06-20 | Added a Rakefile.

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/master” and “origin/HEAD”.
Now look at the “Updated Rakefile” commit. You will see that the local master 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.
