#!/bin/bash
# Stale activity checker
# Runs (e.g. via cron every 5 min). Shuts down instance after 30 min of NO file changes under $MONITOR_DIR.
# Improvements:
#  - Uses a state file to persist the last observed activity timestamp.
#  - Handles empty directories without immediately triggering shutdown.
#  - Works off seconds (no integer minute truncation surprises).
#  - Prevents race conditions with a lock.

#This script will install the cloudformation helper work on Ubuntu 18.
#Some values are hard coded. Make sure to update where needed, or add to the parameters section.
#This would probably work on other distros, but I have not tested yet. Try it out. 
#Just make sure to change things like apt to yum if trying on another OS.
