"du" takes into account block sizes and so on, so may not be the same on
two different machines. "ls -l" shows the exact size per file.

md5sum will generate an MD5 checksum on each file. It's typically what is
used by larger FTP sites to ensure you've downloaded a non-corrupt file.
It's _possible_ for two seperate files to have the same checksum but the
chances of this happening by accident are 1 in 2^128 - very unlikely :-)
