How to use the result code of FTP ?

[lutech]

I have all the FTP return codes, but I don't know how to use it to make sure a seccessful FTP transfer. For example:
ftp -ivn <<EOF >resultfile
open username passwd
cd dest_path
put file_name
quit
EOF
Since there will be more than one result code in &quot;resultfile&quot;, what can I do to ensure the file has been transferred succesfully?

Thanks in advancd.

When I want to be sure the ftp transfer is 100% sucessful I:
1. compute a checksum for the transfered file (command cksum) file_name before the transfer and put it into a file cksum_file_name
2. transfer a file_name
3. transfer a cksum_file_name
4. compute a checksum for an already transfered file
5. compar the new checksum and the checksum in a cksum_file_name

If the checksums are identical you are sure the file was not corrupted during the transfer.
