As other posters imply the sending process needs improvement. There are three common approaches:

1) Transmit each file under a temporary filename, then the transmission process renames each file after the transfer is complete. This is not 100% safe because whole files could be missing.
Also verify that each file is dated today.
2) Transmit each file under a temporary filename, then the transmission process renames each file and then finally transmits an "end of transmission" file to signify the end of the transmission.
Also verify that each file is dated today.
3) Construct a batch of files and send a "start of transmission" file and and "end of transmission file" containing control records for the batch containg a list of files and their respective checksums.
Also verify that each file is dated today.

I use a combination of 2) and 3) with an automatic retry mechanism.


The "fuser" approach is flawed because it will ignore a failed or missing transmission. I can't think of any reliable way of determining whether an incoming ftp has finished just by looking at the incoming file.
