I had to make an alias for rebasing, because I kept doing the opposite:
git checkout master #check out the branch to apply commits to
git rebase mybranch #Apply all commits from mybranch
Now I just write rebase-current-branch
and it does what I want: fetches origin/master and rebases my working branch on top of it.But "ours"/"theirs" still keeps tripping me up.
You can use the --onto flag for git rebase
git rebase --onto origin/master
It will checkout origin/master and replay the current branch on top.P.S. I had to check the man page as I use Magit. In the latter I tap r, then u. In magit my upstream is usually the main trunk. You can also tap e instead of u to choose the base branch.
Tip, you may want to use origin/HEAD over origin/master
