Display dir name in ls -lhtra

OS: Red Hat Linux 6.8

DB: Oracle 11.2.0.3.0 

Question: I have written a small script that gives me the list of files and their size in 3 directories. But it does not gives me directory names. Please advice how to get that directory name? Currently, I can only run it from my directory. Is there anything I can do to run it from any other directory and get the same results?

Scirpt:

#!/bin/sh

ls -lhtra /oracle-backups/test1/backups

ls -lhtra /oracle-backups/test2/backups

ls -lhtra /oracle-backups/test3/backups

Thanks for your help.
