The filewatch utility is not a well known utility, that can be very handy. I have used it especially when I needed process a unix file after it has been copied to a certain directory.
This is the documentation about the filewatch utility:
Th job below is submitted and then waiting and activated when there is a change in the input directory /yourdirectory/testfileloc
The job itself moves the files in the input directory to a processing directory, starts the next “watch” job and then the processing job for the files in the processing directory.
The setup is clearly to test the mechanism – and not necessarily a model for a production-like situation. In a production situation you might want to use TWS applications etc, but that is up to your application design of course.
I hope this helps.
