How To Know Folder Size in Linux

As we all know that the folder in linux was identified as a given file or directory d flag, after the ls command is given will surely display the default size of a folder that is 4096:

andri@bima:/home/andri/repo-10.04$ ls -l

total 16

-r--r--r-- 1 root root 10 2010-05-02 23:00 Archive-Update-in-Progress-ranah.web.id

drwxr-xr-x 7 root root 4096 2010-04-30 19:47 dists

drwxr-xr-x 6 root root 4096 2010-05-01 02:58 pool

drwxr-xr-x 3 root root 4096 2010-05-02 21:12 project

to see the size of a directory or folder can use the du command, for example:

andri@bima:/home/andri/repo-10.04$ du -s

41173756

andri@bima:/home/andri/repo-10.04$ du -hs

40G

andri@bima:/home/andri/repo-10.04$ du -hs /home/andri/repo-10.04

40G /home/andri/repo-10.04/

That's it :)
