# Description: ####
# screensaverfull.sh needs xprintidle and feh to work.

# HOW TO USE: Start the script with the number of seconds you want the checks
# for fullscreen to be done. Example:
# "./screensaver.sh 120"

DIR=$( cd "$( dirname "$0" )" && pwd)
delay=$1


# If argument empty, use 60 seconds as default.
if [ -z "$1" ];then
    delay=60
fi

# If argument is not integer quit.
if [[ $1 = *[^0-9]* ]]; then
    echo "The Argument \"$1\" is not valid, not an integer"
    exit 1
fi
