git log --graph --decorate --oneline should show you names of the commits that have names. Not every commit is associated with a branch name.

Remember, a branch name is just a pointer to a particular commit. Each commit has a parent, so one commit may be a part of the history of a dozen separate branches.

• You can see which branches contain a commit via git branch --contains <ref>.
• If you just need some kind of symbolic name to track down a commit, use git name-rev <ref>.

• If you need a shell-scriptable ("plumbing") list of all branches containing a commit, try this:

  commit=$(git rev-parse <ref>) # expands hash if needed
  for branch in $(git for-each-ref --format "%(refname)" refs/heads); do
    if git rev-list "$branch" | fgrep -q "$commit"; then
      echo "$branch"
    fi
  done
