init

#!/usr/bin/env bash
# init - Post-clone setup: create/rename scripts dir, install .aliases, and update ~/.bashrc (optionally runs fixnano).

# Author: Don Ferris
# Created: 2025-10-24
# Current Revision: v1.1 - 2025-11-14
# ──────────────────────────────────────────────────────
# Revision History
# ----------------
# v1.1 — 2025-11-14 — Add installation of ntfy (used by mediasync.sh and generally useful for very long-running processes). Also added logic allowing init to be run multiple times without rerunning previously run commands.
# v1.0 — 2025-10-24 — Core functionality
