Hi there

I have a Rails app running that needs to have it's database
periodically updated from an upload of a text file.

The data file is in UIEE format and I'm working on a Ruby script that
parses the file and inserts the data into MySQL. That should be OK I
think at this stage.

However I need to automate this process - basically the client is
uploading the UIEE file to a prescribed directory on the remote
server. I then either need to detect whether there has been a fresh
upload OR rely on cron to look into the directory and then parse the
fresh file (if present).

Am I on the right track looking at cron to do this? Maybe I'm better
building an admin page where the user can manually trigger the running
of the database update script? Or is there another unix command that
can detect a change in a directory and thereby trigger the script?

Any clues on how best to approach this situation would be
appreciated...
