git fetch
brings your local copy of the remote repository up to date. For example, if your remote repository is GitHub – you may want to fetch any changes made in the remote repository to your local copy of it the remote repository. This will allow you to perform operations such as compare or merge.git pull
on the other hand will bring down the changes in the remote repository to where you keep your own code. Typically,git pull
will do agit fetch
first to bring the local copy of the remote repository up to date, and then it will merge the changes into your own code repository and possibly your working copy.The only difference between
git pull
andgit fetch
is that :git pull
pulls from a remote branch and merges it.git fetch
only fetches from the remote branch but it does not mergei.e. git pull = git fetch + git merge …
Git Fetch
You download changes to your local branch from origin through fetch. Fetch asks the remote repo for all commits that others have made but you don’t have on your local repo. Fetch downloads these commits and adds them to the local repository.
Git Merge
You can apply changes downloaded through fetch using the merge command. Merge will take the commits retrieved from fetch and try to add them to your local branch. The merge will keep the commit history of your local changes so that when you share your branch with push, Git will know how others can merge your changes.
Git Pull
Fetch and merge run together often enough that a command that combines the two, pull, was created. Pull does a fetch and then a merge to add the downloaded commits into your local branch.
1. Git Fetch- This will Download all the changes that have been made to the origin/main branch project which are not present in your local branch. And will wait for the Git Merge command to apply the changes that have been fetched to your Repository or branch.
2. Git Pull- This will update your local branch with the origin/main branch i.e. actually what it does is a combination of Git Fetch and Git merge one after another. But this may Cause Conflicts to occur, so it’s recommended to use Git Pull with a clean copy.
git fetch
It will download all refs and objects and any new branches to your local Repository…
git pull
It will apply the changes from remote to the current branch in local…
So the difference will be:
git fetch
it will just fetch all the changes in the remote repository (GitHub) and move the origin/master pointer toHEAD
. Meanwhile your local branch master will keep pointing to where it has.git pull
, it will do basically fetch (as explained previously) and merge any new changes to your master branch and move the pointer toHEAD
.Even more briefly
git fetch
fetches updates but does not merge them.git pull
does agit fetch
under the hood and then amerge
.Briefly
git fetch
is similar topull
but doesn’t merge. i.e. it fetches remote updates (refs
andobjects
) but your local stays the same (i.e.origin/master
gets updated butmaster
stays the same) .git pull
pulls down from a remote and instantly merges.More
git clone
clones a repo.git rebase
saves stuff from your current branch that isn’t in the upstream branch to a temporary area. Your branch is now the same as before you started your changes. So,git pull -rebase
will pull down the remote changes, rewind your local branch, replay your changes over the top of your current branch one by one until you’re up-to-date.Also,
git branch -a
will show you exactly what’s going on with all your branches – local and remote.This blog post was useful:

.UPDATE
I thought I’d update this to show how you’d actually use this in practice.
Notes:
On step 2: For more on diffs between local and remotes, see: How to compare a local Git branch with its remote branch
On step 3: It’s probably more accurate (e.g. on a fast changing repo) to do a
git rebase origin
here. See Justinzhao Ohms comment in another answer.See also: http://longair.net/blog/2009/04/16/git-fetch-and-merge/
Note also: I’ve mentioned a
merge
during apull
however you can configure apull
to use arebase
instead.
