Not good way to get size "cut -d' ' -f2"
SIZE="$(curl --silent --location --head --insecure "${LINK}" | grep -i '^Content-Length' | cut -d' ' -f2)"
Because if you use this for variable is will contains additional characters like this:
SIZE=$'597622784\r'
Better user grep:
SIZE="$(curl --silent --location --head --insecure "${LINK}" | grep -oP '(?i)(?<=Content-Length:\s)\d{1,20}(?=\D)?')"
