le probleme est simple ce situe juste après la première boucle  : echo $Ad ne revoiye rien alors que cela ne devrai pas être le cas!

	while [ $Wh1 -lt 10 ];do
		Buff="${f#"${TbStat[$Wh1]}"}"
		if [ "${f%$Buff}" = "${TbStat[$Wh1]}" ] ; then
#			echo "OUI "  "${f%$Buff}" " <===>" "${TbStat[$Wh1]}"

esac
