  git rebase --onto <new_commit_on_which_i_want_to_rebase> <old_commit_of_parent_from_which_i_rebased> <name_of _my_branch>
  git rebase --onto 38b4b02 032d9d6 improve_ci_further

or, if i already checked out the branch to rebase:

  git rebase --onto <new_commit_on_which_i_want_to_rebase> <old_commit_of_parent_from_which_i_rebased>
