you get 3 digit return codes from the other side. Try it out manually, direct the output of the ftp to a file and check it for bytes transferred and transfer complete codes.
Hi, Other way to see if the file is transfered completely is, see on the destination that the file has its permission and ownership set, coz till the file is in progress of tranfer the permissions will be 000 and owner is root.
I think you will automaticate control using a ftp script; ftp has not verify command neither any stop on error; so, unique way is same as tape backup: verify. After send you can receive same files (in other directory) and then compare locally; obviusly you need double transfer time.
We go a step further. We must make 100% sure that the files are correct. We use MD5 to obtain a checksum value prior to transferring, and then transfer the file. Once the file is transferred we have a script that does the MD5 checksum the receiving host. We then do a diff. All of this is done using scripts.
Good luck

When a sys-admin say's maybe, they don't mean 'yes'!
My fdavorite method is to use Perl Net::FTP module. This link has a Perl script attached that make FTP transfers (with error checking and retransmissions) very easy.
Note: It also works unchanged on Windows with one of the free Perls.
