42. Fetching changes

Goals

  • To learn how to pull changes from a remote repository.

Run:

cd ../cloned_hello
git fetch
git hist --all

NOTE: We are now in the repository cloned_hello

Result:

$ git fetch
From /Users/marina/Documents/Presentations/githowto/auto/hello
   6e6c76a..2faa4ea  master     -> origin/master
$ git hist --all

At the moment the repository contains all the commits from the original repo, however they aren’t integrated into the local branches of the cloned repository.

You’ll find the commit named “Changed README in original repo” in the history. Notice that the commit includes “origin/master” and “origin/HEAD”.

Now let’s take a look at the “Updated index.html” commit. You’ll see that the local master branch points to this very commit, not the new commit we’ve just fetched.

This brings us to the conclusion that the “git fetch” command will fetch new commits from the remote repo, but won’t merge them into the local branches.

01Check the README

We can show that the cloned README file has not been changed.

Run:

cat README

Result:

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

No changes, as you can see.
