How to find the nearest parent of a Git branch?

Question

Let\'s say I have the following local repository with a commit tree like this:

master --> a
            \\
             \\
      develop c --> d
               


        

Answer 1

This did not work for me when I had done something like develop > release-v1.0.0 > feature-foo, it would go all the way back to develop, note there was a rebase involved, not sure if that is compounding my issue...

The following did give the correct commit hash for me

git log --decorate \
  | grep 'commit' \
  | grep 'origin/' \
  | head -n 2 \
  | tail -n 1 \
  | awk '{ print $2 }' \
  | tr -d "\n"
