Resolve Git merge conflicts in favor of their changes during a pull

Question

How do I resolve a git merge conflict in favor of pulled changes?

I want to remove all conflicting changes from a working tree without having to go through all of the conflicts with git mergetool, while keeping all conflict-free changes. Preferably, I want to do this while pulling, not afterwards.

Answer 1

git pull -s recursive -X theirs <remoterepo or other repo>

Or, simply, for the default repository:

git pull -X theirs

If you're already in conflicted state...

git checkout --theirs path/to/file

Answer 2

You can use the recursive "theirs" strategy option:

git merge --strategy-option theirs

From the man:

ours
    This option forces conflicting hunks to be auto-resolved cleanly by 
    favoring our version. Changes from the other tree that do not 
    conflict with our side are reflected to the merge result.

    This should not be confused with the ours merge strategy, which does 
    not even look at what the other tree contains at all. It discards 
    everything the other tree did, declaring our history contains all that
    happened in it.

theirs
    This is opposite of ours.

Note: as the man page says, the "ours" merge strategy-option is very different from the "ours" merge strategy.

Answer 3

If you're already in conflicted state, and you want to just accept all of theirs:

git checkout --theirs .
git add .

If you want to do the opposite:

git checkout --ours .
git add .

This is pretty drastic, so make sure you really want to wipe everything out like this before doing it.

Answer 4

OK so, picture the scenario I was just in:

You attempt a merge, or maybe a cherry-pick, and you're stopped with

$ git cherry-pick 1023e24
error: could not apply 1023e24... [Commit Message]
hint: after resolving the conflicts, mark the corrected paths
hint: with 'git add <paths>' or 'git rm <paths>'
hint: and commit the result with 'git commit'

Now, you view the conflicted file and you really don't want to keep your changes. In my case above, the file was conflicted on just a newline my IDE had auto-added. To undo your changes and accept their's, the easiest way is:

git checkout --theirs path/to/the/conflicted_file.php
git add path/to/the/conflicted_file.php

The converse of this (to overwrite the incoming version with your version) is

git checkout --ours path/to/the/conflicted_file.php
git add path/to/the/conflicted_file.php

Surprisingly, I couldn't find this answer very easily on the Net.

Answer 5

If you're already in conflicted state, and do not want to checkout path one by one. You may try

git merge --abort
git pull -X theirs

Answer 6

The git pull -X theirs answers may create an ugly merge commit, or issue an

error: Your local changes to the following files would be overwritten by merge:

If you want to simply ignore any local modifications to files from the repo, for example on a client that should always be a mirror of an origin, run this (replace master with the branch you want):

git fetch && git reset --hard origin/master

How does it work? git fetch does git pull but without merge. Then git reset --hard makes your working tree match the last commit. All of your local changes to files in the repo will be discarded, but new local files will be left alone.

Answer 7

Please not that sometimes this will not work:

git checkout --ours path/to/file

or

git checkout --theirs path/to/file

I did this instead, assuming HEAD is ours and MERGE_HEAD is theirs

git checkout HEAD -- path/to/file

or:

git checkout MERGE_HEAD -- path/to/file

After we do this and we are good:

git add .

If you want to understand more, see wonderful post of torek here : git checkout --ours does not remove files from unmerged files list

Answer 8

VS Code (integrated Git) IDE Users:

If you want to accept all the incoming changes in the conflict file then do the following steps.

1. Go to command palette - Ctrl + Shift + P
2. Select the option - Merge Conflict: Accept All Incoming

Similarly you can do for other options like Accept All Both, Accept All Current etc.,

Answer 9

To resolve all conflicts with the version in a particular branch:

git diff --name-only --diff-filter=U | xargs git checkout ${branchName}

So, if you are already in the merging state, and you want to keep the master version of the conflicting files:

git diff --name-only --diff-filter=U | xargs git checkout master

Answer 10

git checkout --ours/theirs doesn't exclusively resolve conflicts. It checks out (takes the entire file) from either ours/theirs.

Suppose we have a file foo with changes in two commits/branches/trees/whatever. If there was a conflict introduced by theirs, as well as a modification, and we want to resolve the conflict using ours -- then using checkout --ours foo will discard the changes introducing conflicts, but also the modifications.

Using SED

Resolve using theirs:

sed -i -e '/^<<<<<<</,/^=======/d' -e '/^>>>>>>>/d' foo

• -i Modify the file in place,
• /^<<<<<<</,/^=======/d delete everything between and including <<<<<<< and ======= (ours)
• /^>>>>>>>/d delete the remaining conflict marker
• -e specify multiple patterns to SED
• foo the file

Resolve using ours:

sed -i -e '/^<<<<<<</d' -e '/^=======/,/^>>>>>>>/d' foo

I made a script that you can call git resolve -o/-t/-b.

Creating a custom merge tool

You can create custom merge tools. Building on the above sed scripts you can put something like this in your git-config:

[mergetool "ours"]
    cmd = "sed -i -e '/^<<<<<<</d' -e '/^=======/,/^>>>>>>>/d' -- $MERGED"

and call it git mergetool --tool=ours

Merge styles

Note that there are other non-standard merge styles, like diff3 and zdiff3 as pointed out by @Stavros in the comments. The number of conflict markers is also not hard coded to 7 in git. I believe it's mainly just a default and as I recall, it can be configured.

The basic sed script can be tweaked to work with all configurations.

Answer 11

Update 2023!

If you want to accept all current changes and ignore any incoming changes, you could accomplish this:

git merge [branch] --strategy-option ours

[branch] should be replaced with the name of the branch you are merging into your current branch.

If, instead, you know you want to overwrite any current changes and accept all conflicts from incoming changes, you can use the theirs strategy instead:

git merge [branch] --strategy-option theirs

Answer 12

from https://git-scm.com/book/en/v2/Git-Tools-Advanced-Merging

This will basically do a fake merge. It will record a new merge commit with both branches as parents, but it will not even look at the branch you’re merging in. It will simply record as the result of the merge the exact code in your current branch.

$ git merge -s ours mundo

Merge made by the 'ours' strategy.

$ git diff HEAD HEAD~

You can see that there is no difference between the branch we were on and the result of the merge.

This can often be useful to basically trick Git into thinking that a branch is already merged when doing a merge later on. For example, say you branched off a release branch and have done some work on it that you will want to merge back into your master branch at some point. In the meantime some bugfix on master needs to be backported into your release branch. You can merge the bugfix branch into the release branch and also merge -s ours the same branch into your master branch (even though the fix is already there) so when you later merge the release branch again, there are no conflicts from the bugfix.

A situation I've found to be useful if I want master to reflect the changes of a new topic branch. I've noticed that -Xtheirs doesn't merge without conflicts in some circumstances... e.g.

$ git merge -Xtheirs topicFoo 

CONFLICT (modify/delete): js/search.js deleted in HEAD and modified in topicFoo. Version topicFoo of js/search.js left in tree.

In this case the solution I found was

$ git checkout topicFoo

from topicFoo, first merge in master using the -s ours strategy, this will create the fake commit that is just the state of topicFoo. $ git merge -s ours master

check the created merge commit

$ git log

now checkout the master branch

$ git checkout master

merge the topic branch back but this time use the -Xtheirs recursive strategy, this will now present you with a master branch with the state of topicFoo.

$ git merge -X theirs topicFoo

Answer 13

I had a long-running next-version branch with tons of deletions to files that had changed on develop, files that had been added in different places on both branches, etc.

I wanted to take the entire contents of the next-version branch into develop, all in one whopping merge commit.

The combination of the above commands that worked for me was:

git merge -X theirs next-version
# lots of files left that were modified on develop but deleted on next-version
git checkout next-version .
# files removed, now add the deletions to the commit
git add .
# still have files that were added on develop; in my case they are all in web/
git rm -r web

Not a new answer, just combining bits from many answers, partly to reassure that you might need all of these answers.

Answer 14

Accept remote changes (theirs) and in case there are conflicts you get the following error:

fatal: Not possible to fast-forward, aborting.

so you may want to pull and accept their changes with fast-forward:

$ git pull -X theirs --ff

Answer 15

In Emacs using smerge-mode, to resolve all conflict markers using either mine or theirs, we can define:

(defun aj/smerge-keep-mine-all ()
  ""
  (interactive)
  (save-excursion
    (beginning-of-buffer)
    (while (ignore-errors 'user-error (progn (smerge-next) t))
      (smerge-keep-mine))))

(defun aj/smerge-keep-other-all ()
  ""
  (interactive)
  (save-excursion
    (beginning-of-buffer)
    (while (ignore-errors 'user-error (progn (smerge-next) t))
      (smerge-keep-other))))

Answer 16

Even though there are already great answers here, I wanted to post this answer to document how to resolve all merge conflicts in Visual Studio (in favor of our changes as an example).

If instead, you want to accept incoming changes (their changes) as asked in this question, just replace ours in Step 6 below with theirs. It's as simple as that.

---

Summary of what I'm doing here:

Merge dev into my branch and while doing that if there are any merge conflicts, take changes from my branch.

(After this is done, I'll create a PR to finally push the changes from my branch to dev).

---

Step 1

Checkout the branch where you want to merge dev into by going to 'Manage Branches' and double clicking your branch name. In my case, it's feature\InterimBranchToDev2-AshK.

Step 2:

Right click dev and click Merge 'dev' into 'feature/InterimBranchToDev2-AshK'

Step 3:

You'll see a ton of merge conflicts!

Now it's very tedious to right click each of those files and click Keep Current (feature/InterimBranchToDev2-AshK), so let's Abort this and take care of this using command line.

Step 4:

Hit Abort

Step 5:

Open cmd

Step 6:

Type git merge --strategy-option ours --no-commit dev and hit enter

What this basically means: "Merge dev into current branch and if there are any merge conflicts, take version from current branch, and also don't commit the merge yet".

This will be the output: Automatic merge went well; stopped before committing as requested

Step 7:

Now go to Visual Studio, conflicts are nicely taken care of and you can enter your message and commit:

Answer 17

I found that I needed to specify origin main as the branch I was merging into.

git merge **origin main** --strategy-option theirs

Answer 18

Starting with an example, We have a main branch and a dev branch having some conflicts

Pull updates before checkout, so the main branch is up to date:

git checkout main
git pull
git checkout dev

Then merge:

• if you want to accept incoming changes from the main to be the source of truth:

git merge --strategy-option theirs main

• if you want to accept the current changes in dev as the source of truth:

git merge --strategy-option ours main

ours and theirs here are special words, they have meaning and are not custom, but main or dev could be any other two branches you want to merge together.

Answer 19

It's Solved. To resolve all conflicts with below simple steps.

git fetch && git reset --hard origin/master

git pull -X theirs

git pull origin master
