Hello
I was copying some files from one server to other, that I relized the total file size ( sum of all files ) in one server is a bit more than the one that copied from ( about 6 when I do du -s )
"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.
is there any more accurate way to make sure of integrity of the file. ( other than pgp or signature )
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 :-)
