git change master branch to another branch code example

Example 1: git sync branch with master

git checkout master
git pull
git checkout mybranch
git merge master


# to keep mybranch in sync with master

# then when you're ready to put mobiledevicesupport into master, first merge in master like above, then ...

git checkout master
git merge mybranch
git push origin master

Example 2: 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.
