Question

Trivial question.

#!/bin/bash

if test -z "$1"
then
  echo "No args!"
  exit
fi

for newname in $(cat $1); do
  echo $newname
done

I want to replace that echo inside the loop with array population code.
Then, after the loop ends, I want to read the array again and echo the contents.
Thanks.

If the file, as your code shows, has a set of files, each in one line, you can assign the value to the array as follows:

array=(`cat $1`)

After that, to process every element you can do something like:

for i in ${array[@]} ; do echo "file = $i" ; done
