In unix how to find the space occupied ( in Bytes) by the /home directory including all its subdirectories.

The du command outputs the number of kilobyes used by each subdirectory. Useful if you have gone over quota and you want to find out which directory has the most files. but how shuld i use tat in my case.

du -bs ~ will print out total space in bytes used in your home directory and all of its sub-directories, though you may find du -hs to print friendlier numbers.

See also man du

(also probably a serverfault.com or superuser.com question)

@unhillbilly: OP said "/home directory including all its subdirectories" – thejh Dec 15 '10 at 17:03
-s means "including all subdirectories". – Zack Dec 15 '10 at 17:05
@thejh. My words lie, the command does not. I shall correct. Thank you! – unhillbilly Dec 15 '10 at 17:06

Try this:

du --bytes /home

If you really just want the number:

du --bytes -s /home|cut -f 1

If you really want just the number, don't you use du --bytes -s /home? – Jonathan Leffler Dec 15 '10 at 17:14
@Jonathan Leffler: You will still need to cut, but yes, the tail was unnecessary. removing it. – thejh Dec 15 '10 at 17:28

Although it doesn't use the command line, I like to use KDirStat to see the usage of space. I'm just a visual guy.
