how to move master branch to main branch

# Step 1 
# create main branch locally, taking the history from master
git branch -m master main

# Step 2 
# push the new local main branch to the remote repo (GitHub) 
git push -u origin main

# Step 3
# switch the current HEAD to the main branch
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main

# Step 4
# change the default branch on GitHub to main
# https://docs.github.com/en/github/administering-a-repository/setting-the-default-branch

# Step 5
# delete the master branch on the remote
git push origin --delete master

git change master branch

## 1) Rename master branch to oldmaster.
git branch -m master oldmaster
#Now there is no master branch on my local machine.

## 2) Rename my masterTemp branch to master
git branch -m masterTemp master
#The branch which was named masterTemp on my local machine is now master

## 3) Delete the branch from remote
git branch -rD master

## 4) Push the new master branch to remote
git push --force origin master

git move change from master to new branch

git stash						//you can stash the changes in the master branch .
git checkout -b newbranchname	//then checkout the branch
git stash pop					//and pop the changes here

how to move master changes to branch

git checkout -b newfeat master
git rebase --onto working-branch origin/master newfeat
git checkout master
git reset --hard origin/master

At this point you have:
*master pointing to the last pushed commit (origin/master)
*working-branch never changed
*a new newfeat branch that contains all the new commits and is ahead of working-branch.

Move you changes to your new branch from master

make your changes on master
creat new branch  my_branck and checkout the new branch
git add .
git commit 
git push
git checkout my_branch
git checkout master
to make sure your master is clear `git clewan -f`
