Using inotifywait with queue directories
After writing Using directories as queues I realized I did not mention how you should check the queue. Using a cron job is usually adequate. However, this does mean your script will be polling the queue-directory and having to distinguish been an empty and a non-empty queue-directory. If you don't like polling then use inotify and specifically inotifywait (part of the Ubuntu package inotify-tools). For example, this command line will monitor the directory /queue/new and when files are added to or moved into the directory the word count command is run.
