We were sorting numerical values with the 'sort' tool without telling it that we are sorting numbers, giving us unexpected ordering. So just pass the '-n' option to the 'sort' tool. Example: $ echo -e "11\n9\n20" | sort 11 20 9 $ echo -e "11\n9\n20" | sort -n 9 11 20 Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Eryu Guan <guaneryu@gmail.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
