This happen before, but just to help, this is what i use.
It's just du, wrapped to operate on your files.

For example, to walk /usr/nemo to find files with execute permission:

; walk /usr/nemo 'test -x $f && echo $f'

you can pass any command and use $f where you want the file name.

#!/bin/rc

rfork e

if (~ $#* 0) {
	echo 'usage: walk file [cmd...]' >[1=2]
	exit usage
}

file=$1
shift
if (~ $#* 0)
	cmd='echo $f'
if not
	cmd=$*
cd `{basename -d $file}
exec du -a $file | awk '{print $2}' | while (f=`{read}) { eval $cmd  }
