Git: squash & rebase

.aliases

# @arg int: The number of commits you want to squash.
function squash() {
  num=${1};
  if [ ! num ]; then
    echo "Integer required";
    return 0;
  fi
  git reset --soft HEAD~${num};
  git commit --edit -m"$(git log --format=%B --reverse HEAD..HEAD@{1})";
}

# @arg string: The branch you are applying your changes "on top of".
function rebase() {
  rebase_on=${1};
  status=`git status --porcelain`
  if [ -z ${status} ]; then
    branch=$(git symbolic-ref --short -q HEAD)
    git checkout ${rebase_on}
    git pull
    git checkout ${branch}
    git rebase ${rebase_on}
  else
    echo "Commit your changes: ${status}"
    return 0;
  fi
}

Great functions, however please change the name of the variable 'status' in the rebase function to avoid an error with zsh.
