> TWO INTERESTING tiny scripts below, from *Wicked Cool Shell Scripts* (Dave
> Taylor, No Starch Press, 2004, San Francisco). Both combine to implement a
> simple calendar program that help you keep track of the events. Extremely
> useful in the real world of work...
>
> The first script, *addagenda*, enables you to specify either recurring or
> one-time events. All dates are validated and saved, along with one-line
> event description, in an *.agenda* file in your home directory.
>
> For its part, the second script, *agenda*, checks all known events,
> showing which are scheduled for the current date. Useful for remembering
> birthdays, events, appointments, schedules.
>
> HOW IT WORKS: Weekly, annual and one-time events are accepted. As entries
> are added to the agenda file, their specified dates are 'normalized' and
> compressed so that 3 April becomes 3Apr, and Thursday becomes Thu. The
> *agenda* script checks for events by taking the current date and
> transforming it into three possible date string formats. It then simply
> compares each of these date strings to each line in the *.agenda* data
> file.
>
> This script, writes Dave Taylor, just "scratches the surface of this
> complex and interesting topic". It would be nice to have a look a few days
> ahead. This script could be used on a *nix box to send out systemwide
> reminders. Imagine newspaper reporters getting a reminder of what's on the
> schedule on that day. Simply have the *agenda* script on each user's
> machine point to a shared read-only .*agenda* file, and then add a call
> to the agenda script in each user's *.login* or similar file.
