How to get size of Linux folders and subfolders?

[Elliott]

I’m trying to get size of a folders and sub-folders in Linux file system by using ls –la command.
But it's the giving me the summarized size. Is there another command that would achieve this?

Refer the following command to get size of Linux folders and sub-folders.

du -sh /*

-s - to give only the total for each command line argument.
-h - for human-readable format (optional).
/* - simply expands to all directories (and files) in /.

To check more than one directory and see the total, use:

du -sch

-c - Produce a grand total
