Pull merge request to new branch
git fetch origin merge-requests/REQUESTID/head:BRANCHNAMEi.e
git fetch origin merge-requests/10/head:file_uploadCheckout to newly created branch
git checkout BRANCHNAMEi.e (
git checkout file_upload)
OR with single command
git fetch origin merge-requests/REQUESTID/head:BRANCHNAME && git checkout BRANCHNAME
i.e
git fetch origin merge-requests/18/head:file_upload && git checkout file_upload

10To fetch updated changes from the pull request, simply do a git pull on the branch, `git pull origin merge-requests/10/head` – Taranjeet Jul 26 '18 at 10:09

Unfortunately, this does not work for closed Merge Requests – Klaas van Schelven Dec 15 '21 at 11:15

This is also documented in GitLab online documentation : https://docs.gitlab.com/ee/user/project/merge_requests/reviewing_and_managing_merge_requests.html#checkout-merge-requests-locally-through-the-head-ref
They supply this script (git alias) :
[alias]
mr = !sh -c 'git fetch $1 merge-requests/$2/head:mr-$1-$2 && git checkout mr-$1-$2' -
Then you can use this command :
git mr origin 4
So a new local branch mr-origin-4 will be created.

3Thanks for this hint. It works. However, how to push back commits to this particular MR? – Alex Feb 25 '21 at 07:33

You can also add the line
fetch = +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/*
to your .git/config (section [remote "origin"] or replace origin with your remote's name) to have git fetch fetch all merge requests. This line is in addition after any already existing fetch line (the + causes this to be added, not replacing).

@KanagaveluSugumar You mean `git cherrypick`? Otherwise please [ask a new question](https://stackoverflow.com/questions/ask) – Tobias Kienzler Jan 27 '21 at 18:05

In gerrit i can fetch particular patch set with command like `git fetch ssh://user@gerrit.it.**.com:29418/OneSearch/controller/xx refs/changes/30/1228430/3 && git checkout FETCH_HEAD` where `3` is the patch set pushed to the review 1228430. Is there any such option in gittlab MR? – Kanagavelu Sugumar Jan 28 '21 at 06:21

So I dont want latest change/patch in the MR, instead a particular patch set after the review created. e.g. Say once MR is created if user has pushed multiple changes from the initial code. Each code change push will be a revision/patch right? in that i need to download locally a particular change/patch set to test. – Kanagavelu Sugumar Jan 28 '21 at 06:30

@KanagaveluSugumar I'm afraid I don't know, you'll have to ask a separate question instead, maybe someone else knows – Tobias Kienzler Jan 28 '21 at 11:50

/git/config has multiple sections. Which section should this line be added to? And in that section, there may already be a line that starts with "fetch =". What do do in that case? – Mike Nakis May 30 '23 at 10:36

There is a Check out branch button in GitLab.
Then you can copy comments from Step 1. Fetch and check out the branch for this merge request.
git fetch <repo> <branch>
git checkout -b <branch>
