[SOLVED] List files by size (easy-ish) - pass list to a bash script (difficult)

I had a nice little script, sadly I deleted the notes I took and I cannot recreate it.

I want to loop through a folder of files, order by size - biggest first, then pass that to a bash script to process it.

ls -lS | awk '{print $9}'

But some files have spaces and it only prints the first word of the filename :-(
