Task scheduling using Ruby?

[nkb]

Hi.
I would like to schedule a task (e.g check if a file exists or if the
date of the files in a diretory are newer than yesterday, etc.) on Linux
using Ruby. Can this be done, if so how? I supposed I would run the
script as root background? Thanks for any pointer!!

Gavin Kistner released something two weeks ago that might interest you:

http://phrogz.net/RubyLibs/rdoc/classes/Dir/DirectoryWatcher.html

A DirectoryWatcher keeps an eye on a certain directory, firing off your own custom
procs when a file is added to, modified in, or removed from that directory.

See the link above for documentation. Download available from
http://phrogz.net/RubyLibs/DirectoryWatcher.rb

If that doesn't get you in the right direction, ask us again...

Thanks.
I downloaded DirectoryWatcher.rb.
I copied and pasted the codes under the Example: section (uncommented
them) to the end of the DirectoryWatcher.rb. And instead of using
'plugins/devices', I replaced it with 'C:/temp'.
I ran DirectoryWatcher.rb at my command prompt on windowsXP. Nothing
happens when I change or add files to the C:/temp.
What am I missing? Thanks.
