After rcp -rp from remote host, using du -k to verify the file size but total file size have different size. Check on individual file, file size is correct.
How can I confirm on the file size after ftp?
Pls advise.
Thank you.
cluster size?
all you are interested in is the exact byte length of the file and possibly it's MD5 signature, the space on disk is much less of a concern.
Sorry, I'm using wrong categories - UNIX for advanced & Expert Users where I should use the basic one..
This is one of the example.

Did you notice?
When the sizes of the files in a directory are listed, a
total count of blocks, including indirect blocks, is
printed.
Try the following..
ls -ld * | wc -l
ls -ld .* | wc -l
on each.
both node shows the same:
# ls -ld * | wc -l
6
# ls -ld .* | wc -l
2
So
(a) you have all the files
(b) the file byte lengths are correct.
I would count that as success.

Yes, I noticed.. can u pls explain? Thanks.
It says block size, not sector size.
What are the two systems? What are the disk formats/file systems, and how big are the disks?
Sun Solaris.
Source: - veritas file system
/dev/vx/dsk/devappdg1/vol04
60G 16G 43G 28% /linxnet/server2
Target:
/dev/md/dsk/d54 59G 13G 46G 23% /linxnet/server2
Thanks for your advise.
Is this problem due to different file system?
Is it actually a problem, or just a fact?
Besides checking each file size, how can I confirm ftp of all files is correct since this is the fact? Need your advise. Thank you.
The best way is to get an MD5 checksum generated at the server end, then you can compare it at the client end with the MD5 of whatever you downloaded (and after confirming the lengths are correct).
man md5
You'll see this technique used on the internet where, for example, CDs will have both an iso and a md5 checksum file.
You can use cksum as well. It might be more commonly available than md5sum.
If using Solaris 10 md5 is also available using the digest command.
# digest -a md5 /etc/hosts

Hi All,
Thanks for the response.
HOw should I verify those files that already copied over from different node? As there are more than 100 files in one sub directory, what command should I use to verify the file size in one directory instead of checking each individual file size?
