Pull changes

To illustrate "git pull" make a modification to any file in your test repository and commit/push it.

Edit the file in the online editor:

Now let's fake a real world scenario; someone else is going to edit the To fake this, go to the Github or GitLab website and modify the file. Make a commit using the website. Don't create a new branch.

Pull the changes:

Now that someone else has modified the file, you may want to retrieve the changes as well.

This is how you retrieve changes:

git pull origin master
You will get something similar to this:

remote: Counting objects: 3, done.
remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (3/3), done.
 * branch            master     -> FETCH_HEAD
   0ca4277..9d7c096  master     -> origin/master
Updating 0ca4277..9d7c096
Fast-forward | 1 +
 1 file changed, 1 insertion(+)
Take a look at the following line:

Updating 0ca4277..9d7c096
You probably remember the 0ca4277; this is your initial commit. The 9d7c096, however, is the new commit from "someone else".

See the difference:

To see what has changed between your initial commit and this new one:

git diff 0ca4277 9d7c096
You will see a diff.
