$ bx script-encode --help

Usage: bx script-encode [-h] [--config VALUE] [SCRIPT]                   

Info: Base16 encode a plain text script.                                 

Options (named):

-c [--config]        The path to the configuration settings file.        
-h [--help]          Get a description and instructions for this command.

Arguments (positional):

SCRIPT               The plain text script tokens that make up the       
                     script. Multiple tokens must be quoted. If not

Example 3: Creating Multi-signature Addresses

Create a "2 of 4 multisig" payment address for a P2SH transaction to spend on the TEST (196) network. The input script follows a pattern, and requires all 4 public addresses of the signatories that can authorize a P2SH transaction. Smaller compressed public keys are used in the example below.

echo "2 [ 020ae29f86f404e4b302cfa17ff15d93149af6a54c80a4172d47e41f55f6a78d73 ] [ 03664d528eb80096671ef9011c533ceb5df133238e3690d88f2960c786398b86b1 ] [ 029a449ea4a2155ea10002d704604bb3e8606631d35af20889a74b82b2dab572f6 ] [ 0321602d78046d63256b1730b119b1aca3428039f18fdb73ccf45ad3e148dd9b17 ] 4 checkmultisig" | bx script-encode | bx bitcoin160 | bx address-encode -v 196
