The following script can be used to run the TapeTrack Synchronization command whenever a file is uploaded with FTP or SFTP.

The script does the following:

1. Listens using inotify for a change to the directory /var/sftp/user/upload.
2. Spawns a separate thread to run the syncronization.
3. Writes output to the reports directory with a time and date stamp.
4. Loops back to listen to for the next uploaded file.
