Using Git, show all commits that exist *only* on one specific branch, and not *any* others

Question

Given a branch, I\'d like to see a list of commits that exist only on that branch. In this question we discuss ways to see which commits are on one branch

Answer 1

Another variation of the accepted answers, to use with master

git log origin/master --not $(git branch -a | grep -Fv master)

Filter all commits that happen in any branch other than master.
