How to undo an amend commit

git reflog is useful

# Move the current head so that it's pointing at the old commit  # Leave the index intact for redoing the commit  git reset --soft HEAD@{1}    # commit the current tree using the commit details of the previous  # HEAD commit. (Note that HEAD@{1} is pointing somewhere different from the  # previous command. It's now pointing at the erroneously amended commit.)  git commit -C HEAD@{1}
