Assigning du values to array

Question

I'm creating a function that gets an unspecified number of file names in input and returns an array with the size of all the files. I'm using du to check the file size, but I'm not sure on how to assign every file size to a different element of the array. What I've done so far (not working)

for i in size
do
size[i]=$(du -h "$@")
done

You can try this:

#!/bin/bash

size=($(du -h "$@" | awk '{ print $1 }'))
echo ${size[@]}

Sample call:

./script.sh config README.md

Sample output:
