small shell script to make sure the living room computer can only play christmas music

christmasSpirit.sh

#!/bin/bash

while true
do
hasChristmasSpirit=false;
curSong=$(spotify-control getTitle)
declare -a whitelist=("christmas" "Lord" "Winter" "Xmas" "snow" "rudolph" "cold" "sleigh" "frosty");


## loop trough array of christmas spirit
for i in "${whitelist[@]}"
do
  if echo $curSong | grep -iq $i
  then
    hasChristmasSpirit=true
  fi
done

if $hasChristmasSpirit
then
  echo "christmas spirit found!"
else
   spotify-control next
  echo "no christmas spirit found"
fi

sleep 1
done
