Hey so I've the most convenient way to get the largest file size to print in a format of

(Values in this output only serve as an example

> 
> Largest file size: 2015  
> 
>  Size of an average file: 1132
> 
> 
> 

so to get the largest file size, i'd probably use the command 

`find . -type f -ls | sort -r -n -k7 | head -n 1` 

This will print a lengthy list of multiple attributes and print the largest of them (based on their file size)

Issue is, I can't really find a way to get only the actual file size and nothing else

In similar fashion, what I want is to get the average file size.

So I need to find a way, to sum the file size of all the files and then divide it through number of files

To get the number it is quite easy, just a simple (find . -type f | wc -l)
bigger issue is about the summary.

Ideally I'd like the solutions to be in a simple format of

eg. `echo "Largest file size: $(find . -type f | command | command)"` 

Thank you.
