How would I display a directory structure including all its sub-directories and their relative file size information in a tree like format?

Thanks

Did you try:

find /mydir -ls

where /mydir is the directory you want to list.

Yes, However, what I am really looking for is a way to print out the tree like structure of a given dir like below:

/
----> /home
-------------->/home/aaa
--------------->/home/test
------------------------>/home/test/7.1
------------------------>/home/test/7.2
--------------->/home/prod
--------------->/home/lastone
----->/opt
..
..

Thanks for your help

use the du command, Its neerly what you want

Thank You.
