git checkout custom_branch && git rebase master

This will update custom_branch with changes from master branch.

Don't forget to make sure master is up to date first. git pull


This is also possible with git checkout custom_branch && git merge master

How do I safely merge a Git branch into master? - Stack Overflow
A new branch from master is created, we call it test. There are several developers who either commit to master or create other branches and later merge into master. Let's say work on test is taking several days and you want to continuously keep test updated with commits inside master. I would do git ... More on stackoverflow.com

Super dumb question, How to merge origin/master into my branch in one commit?
There isn't a way to do exactly what you want. If the merge was the other way you would squish the commits before merging, but in this case it would be a bad idea. If you squish the new commits on master and merge the squished commit into your branch, it will be fine until you try to merge your branch back into master. At that point the squished commit will count as a new commit on your branch as it doesn't exist on master which will of course cause conflicts. If you want to keep your branch up to date with master but not have a messy history then I recommend rebasing your branch on top of master. This achieves a similar effect to the merge except instead of creating a merge commit, it basically moves the commits on your branch and places them as if you had originally started the branch from the latest commits to main. If you don't want to rebase (re-writing history can be problematic), then I'm not aware of any other way except for putting up with the messy history. More on reddit.com

How to Merge Master into a Feature Branch
I wouldn't. I usually just rebase feature branches onto master when they diverted too much. Unless this branch is collaborative, it should pose no issues. Just do so locally: [assuming you're on the feature branch and the remote is called origin] git fetch git rebase origin/master git push --force-with-lease More on reddit.com

You can either git merge master or git rebase master.

If the branch has not been distributed to other people, in this case i would prefer git rebase.

Because git rebase makes it as if the changes on the feature branch were made on top of the changes on the master branch, which makes the version graph simpler.

Rebase

Taking the example from the git rebase manual, git rebase master in branch feature:

      A---B---C feature                             A'--B'--C' feature
     /                   --rebase-->               /
D---E---F---G master                  D---E---F---G master

However, git rebase is only suitable when nobody else is working on it, or there will be confusion and extra work for them, because the old commits A, B, C are now replaced by new commits A', B', C', plus F and G that were not there before.

The actual result after git rebase master in branch feature is this:

      ( A---B---C ) feature@{1}
       /
      /       A'--B'--C' feature
     /       /
D---E---F---G master

Commits A, B, C are dangling after the rebase, but are reachable through git reflog feature as feature@{1}.

Merge

If someone has pulled your branch, or you have pushed it somewhere, you should merge into it instead, to avoid confusion and extra work on the other end. See Recovering from upstream rebase.

This is the result of git merge master in branch feature:

      A---B---C feature                    A---B---C---M feature
     /                   --merge-->       /       ,---’
D---E---F---G master                 D---E---F---G master

Alternatively, if you git merge feature in branch master, it would look like this:

      A---B---C feature                    A---B---C feature
     /                   --merge-->       /         \
D---E---F---G master                 D---E---F---G---M master

Git Branch Merge
To combine the changes from one branch into another, use git merge. Usually, you first switch to the branch you want to merge into (often main or master), then run the merge command with the branch name you want to combine in.

How I would do this

git checkout master
git pull origin master
git merge test
git push origin master

If I have a local branch from a remote one, I don't feel comfortable with merging other branches than this one with the remote. Also I would not push my changes, until I'm happy with what I want to push and also I wouldn't push things at all, that are only for me and my local repository. In your description it seems, that test is only for you? So no reason to publish it.

git always tries to respect yours and others changes, and so will --rebase. I don't think I can explain it appropriately, so have a look at the Git book - Rebasing or git-ready: Intro into rebasing for a little description. It's a quite cool feature

This is a very practical question, but all the answers above are not practical.

Like

git checkout master
git pull origin master
git merge test
git push origin master

This approach has two issues:

  1. It's unsafe, because we don't know if there are any conflicts between test branch and master branch.

  2. It would "squeeze" all test commits into one merge commit on master; that is to say on master branch, we can't see the all change logs of test branch.

So, when we suspect there would some conflicts, we can have following git operations:

git checkout test
git pull 
git checkout master
git pull
git merge --no-ff --no-commit test

Test merge before commit, avoid a fast-forward commit by --no-ff,

If conflict is encountered, we can run git status to check details about the conflicts and try to solve

git status

Once we solve the conflicts, or if there is no conflict, we commit and push them

git commit -m 'merge test branch'
git push

But this way will lose the changes history logged in test branch, and it would make master branch to be hard for other developers to understand the history of the project.

So the best method is we have to use rebase instead of merge (suppose, when in this time, we have solved the branch conflicts).

Following is one simple sample, for advanced operations, please refer to http://git-scm.com/book/en/v2/Git-Branching-Rebasing

git checkout master
git pull
git checkout test
git pull
git rebase -i master
git checkout master
git merge test

Yep, when you have uppers done, all the Test branch's commits will be moved onto the head of Master branch. The major benefit of rebasing is that you get a linear and much cleaner project history.

The only thing you need to avoid is: never use rebase on public branch, like master branch.

Never do operations like the following:

git checkout master
git rebase -i test

We can then push the merges back to the remote repository's version of the branch. The commits are those that were committed by others to the remote repository's main branch. Notice that we could skip the first two lines and change the merge to merge origin/main to also effect a merge from the remote main into the current branch.

Not sure if this is the right place to ask this. My branch is behind origin master by many commits, I tried to git merge master to my branch earlier but my git log history now shows a bunch of other people’s commits, but I actually just wanted to keep my branch up-to-date with master in one commit only, something like “Merge branch ‘master’ into ‘some-branch’” any help is appreciated.
