LINUX: how to detect that ftp file upload is finished

Question

In my project I have a file uploading feature. Files are uploaded via FTP. I need to configure a listener that will check for new files and invoke a script only when file up

Answer 1

I have used the HiddenStores feature of Proftpd. It keeps in-transit files hidden by prefixing them with a .in.filename.ext until they have finished uploading. Your process can then safely list the directories for completed files.
