[uug] automatically execute a shell script?

[Richard Miller]

Hi!  I am running Mac OS X and have a question about shell scripts:

Can I have a shell script run automatically whenever certain files are 
modified?

I put together a small shell script to upload my iCalendar files to my 
web server (I am using PHPiCalendar to view them) but I have to 
personally run my script anytime I modify my calendars.  I would like 
that to be done automatically.

BTW, I learned how to use cron yesterday, but I think I would still 
prefer that the files be uploaded whenever they are modified as opposed 
to on a regular schedule.

Any help appreciated!  Thanks!
