#    auto-restart.sh
#
#    This script is intended to be launched by a cronjob task every minute
#    to check for any offline game servers. The cronjob would look like this:
#        * * * * * /path/to/auto-restart.sh
#
#    (this script assumes every game server has it's own startup script and a unique screen name)
#
#    You can add as many servers as you like. HOWEVER, keep the name the same
#    BEFORE the equal sign. e.g. server1, server2, server3. & start_svr1, start_svr2,
#    start_svr3.
#
#    Screen names should be unique enough that the full name of one server isn't found in another.
#    e.g. L4D2_svr1 & L4D2_svr2 would be OK, but this would be problematic: L4D2_svr & L4D2_svr2
#
#    EXAMPLE customization:
#    NUM_SERVERS=3
#
#    server1=L4D2_svr1  // screen names, assigned in startup script ("screen -mdS L4D2_svr1")
#    server2=L4D2_svr2
#    server3=CSGO_svr
#
#    start_svr1=/path/to/l4d2svr1.sh    // path to each server's start (bootup) script
#    start_svr2=/path/to/l4d2svr2.sh
#    start_svr3=/path/to/CSGOsvr.sh

# The three checks before launching a game server are because the "alive" variable can sometimes incorrectly return a value of 1 (no server detected)
#  https://i.imgur.com/UDsFTil.png      so it would relaunch the game server when it's already running...
