CentOS - Nov 2007 - How to know when files have finished FTPing?

Hello:

I have a server set up a CentOS 5 server for a client 
to push files onto using FTP.

I have a cron job to process the files and
move them to another directory.

Sometimes, the cron job executes while the client
is still uploading a file (Some of them can be large)
and I get a partial file.

Is there a way to tell when a file has finished
uploading?

I am using the vsftpd daemon installed using yum.

Thanks,
	Neil

One thought that comes to mind is to upload a file containing the md5sums 
of the other files.

Your script would then read the check file and compare the md5sum of each 
file with the one recorded in the check file.  Good files are copied, bad 
files are left until the next time.

how about just watching the logfile rather than the file directory ? the 
log entry for a file is only written once the file has completed... 
since it includes the file size and status of transfer.

Wow, all quite involved answers.

You may be able to get the list of files to process using 'find'.  If
you check using "-mmin +X", you might be able to get only files that
haven't been updated in X minutes.  That should filter out anything in
progress.  If a transfer is stopped in the middle, then restarted
later, that wouldn't help here.

It's possible that the FTP daemon might not update this information,
so you'll have to expieriment.  It's worth a shot before you start
telling the client to modify their process.
