#!/usr/bin/env bash
#
# lncli against one node of the regtest fixture. The node name is required,
# because the fixture runs three of them.
#
#   bin/ln-cli alice getinfo
#   bin/ln-cli bob listchannels
#   bin/ln-cli carol addinvoice --amt=1000
#
# --lnddir is passed explicitly: 'docker compose exec' lands as root, whose HOME
# is /root, but lnd's datadir is /home/lnd/.lnd. Without it lncli looks for the
# TLS cert in the wrong place and fails.
