Questions tagged [bitcoin-cli]

The Bitcoin-Core wallet provides a Command-LIne-Interface (CLI) that can be used to retrieve information from the wallet or to perform certain actions.

This command-line interface is available in the "console" window that can be opened within the Bitcoin-Core graphical User Interface (GUI). The CLI is intended to be used interactively by a person typing commands. The CLI commands are mostly the same as the RPC commands that are available in the Remote Procedure Call (RPC) interface that is intended for use by other programs.

How to generate SegWit address
