worldbox-observer-mod/scripts/worldbox-ctl.sh

#!/usr/bin/env bash
# Canonical WorldBox process control for IdleSpectator agents.
# Always run this script (or harness-run.sh) with unrestricted / `all` permissions.
# Never invent ad-hoc pkill -f patterns that include the worldbox path in the
# agent shell command line - that can kill the agent itself.
#
# Usage:
#   ./scripts/worldbox-ctl.sh status
#   ./scripts/worldbox-ctl.sh start
#   ./scripts/worldbox-ctl.sh stop
#   ./scripts/worldbox-ctl.sh restart   # stop + start + wait for IdleSpectator ready
