Create a bash script called org.sh that takes as an argument a directory name, and organizes the files in that directory into buckets. All files are named $$n$.$txt$,$ where n is a number between $1$ and $100$ inclusive. The buckets are just directories through which we organize these files, and we want $5$ buckets for values $1-20,21-40,41-60,61-80,81-100.$ To keep your directory structure clean, put these buckets in a directory called buckets
