  //for i := 0; i < 1502; i++ {
  for i := 0; i < 3; i++ {
    command := "aws s3 cp --acl public-read-write nft/parachain/" + fmt.Sprintf("%v", i) + " s3://nft-data.raindrop.link/nft/parastate/" + fmt.Sprintf("%v", i)


    fmt.Println("== executing command: %s \n", command)
    // 这里每个参数都要有个空格  
    // fmt.Sprintf("%v", 3) 就是把数字转换成String 
    out, err := exec.Command("aws", "s3", "cp", "--acl", "public-read-write",
      "nft/parachain/" + fmt.Sprintf("%v", i), "s3://nft-data.raindrop.link/nft/parastate/" + fmt.Sprintf("%v", i)).Output()

    if err != nil {
      fmt.Printf(" ERROR: %s", err)
    }else{
      fmt.Printf(" OK: %s", out)
