#!/bin/bash
# A simple cron script that restarts Minecraft servers with an hour's notice
# Created by jflory7 <[email protected]>

# NOTICE ABOUT BROADCASTS
# This script assumes you use a plugin such as Spigot-Essentials or EssentialsX for broadcasting notifications. If you use something different, you should replace "bc"
# in this script with your preferred broadcasting plugin command.

# VARIABLES
# These are all of the variables used in the script. Make sure you change all the names below to the actual names of your tmux sessions or else this script will not work.
# To see what all of your tmux sessions are, type `tmux ls`
TMUX_SESSION_1=hub
TMUX_SESSION_2=survival
TMUX_SESSION_3=creative
TMUX_SESSION_4=skyblock
TMUX_SESSION_5=testing

# SCRIPT BODY
# By default, this script assumes you have five tmux sessions each running their own Minecraft server instance. If you have fewer than five servers, delete or comment out
# the extra lines that do not apply to you to prevent the script from yelling at you. If you have more than five servers, add a new variable above and copy the formatting
# of the other lines.
