what does xargs du -h do?

Question

the command is

find /etc -type f | xargs du -h

I know that it basically means find all files in /etc but I'm not too sure on what the du -h does to it.

Thanks.

Answer 1

du gives you the disk usage.

The -h switch shows the disk usage in human-readable format.

See http://linux.die.net/man/1/du

Answer 2

The du command reports on disk usage. The -h option prints in human units (e.g. 2.0K for 2 KiB).
