sed高手求助

type NideshopUserLevel struct {
    Id          int    `orm:"column(id);auto"`
    Name        string `orm:"column(name);size(30)"`
    Description string `orm:"column(description);size(255)"`
}
type NideshopUserCoupon struct {
    Id           int    `orm:"column(id);auto"`
    CouponId     uint8  `orm:"column(coupon_id)"`
    CouponNumber string `orm:"column(coupon_number);size(20)"`
    UserId       uint   `orm:"column(user_id)"`
    UsedTime     uint   `orm:"column(used_time)"`
    OrderId      uint32 `orm:"column(order_id)"`
}
type NideshopUserLevel struct {
    Id          int    `orm:"column(id);auto"`
    Name        string `orm:"column(name);size(30)"`

}

用 sed 把重复的结构体 NideshopUserLevel {} 去掉,文件内还有未知的重复.
