du reports how much space the file takes on the disk. This # depends on the
block size of each file system.

Hello DBAs,
Though this is not exactly a mysql problem, but I think this list may
be helpful for my question.
I have dumped a mysql data file, and scp it to another host.
The current host is ubuntu-8.04, the remote host is ubuntu-9.10.
As you can see below:
The current host:
$ md5sum fcm.0812.sql.gz
ea08ec505c1b1724213538fed7483975 fcm.0812.sql.gz
$ lsb_release -r
Release:8.04
$ du -k fcm.0812.sql.gz
418080 fcm.0812.sql.gz
The remote host:
$ md5sum fcm.0812.sql.gz
ea08ec505c1b1724213538fed7483975 fcm.0812.sql.gz
$ lsb_release -r
Release:9.10
$ du -k fcm.0812.sql.gz
417672 fcm.0812.sql.gz
Though the files in two hosts have the same md5sum, but why they have
different size with 'du -k' showed?
Thanks.
