$ bx hd-new --help

Usage: bx hd-new [-h] [--config VALUE] [--version VALUE] [SEED]          

Info: Create a new HD (BIP32) private key from entropy.                  

Options (named):

-c [--config]        The path to the configuration settings file.        
-h [--help]          Get a description and instructions for this command.
-v [--version]       The desired HD private key version, defaults to     
                     76066276.                                           

Arguments (positional):

SEED                 The Base16 entropy for the new key. Must be at least
                     128 bits in length. If not specified the seed is    
                     read from STDIN.

This command supports the testnet configuration setting.
