geth lists the non-zero balance accounts and the next zero balance account from your Ledger Nano.

How can I get a list of accounts from my Ledger Nano S wallet, including the next block of unused accounts?

function padLeft(s, n) {
  var result = s.toString();
  while (result.length < n) {
    result = " " + result;
  }
  return result;
}

function listNanoAccounts(from, to) {
  if (from == null) {
    from = 0;
  }
  if (to == null) {
    to = 9;
  }
  var nanoUrl=personal.listWallets[personal.listWallets.length-1].url;
  var nanoPathPrefix="m/44'/60'/0'/";
  var total = new BigNumber(0);
  console.log("  # Account                                                        Ethers");
  console.log("--- ------------------------------------------ --------------------------");
  for (var i = from; i <= to; i++) {
    var account = personal.deriveAccount(nanoUrl, nanoPathPrefix + i, true).address;
    var weis = eth.getBalance(account);
    var balance = web3.fromWei(weis, "ether");
    total = total.add(balance);
    console.log(padLeft(i, 3) + " " + account + " " + padLeft(balance.toFixed(18), 26));
  }
  console.log("--- ------------------------------------------ --------------------------");
  console.log("    Total                                      " + padLeft(total, 26));
  console.log("--- ------------------------------------------ --------------------------");
}
