解决本地分支和远程历史分叉问题

git fetch origin --prune
  current=$(git branch --show-current)
  git for-each-ref --format='%(refname:short) %(upstream:short)' refs/heads | while read b up; do
    [ -z "$up" ] && continue
    if [ "$b" = "$current" ]; then
      git reset --hard "$up"
    else
      git branch -f "$b" "$up"
    fi
  done
