For anyone interested, attached below (in the Extended Entry) is the script I run nightly from cron that informs me by email when my current iPhoto Library is getting big enough to consider taking an action with iPhoto Library Manager to create a new one.
A couple of notes:
(1) Yes, the script uses the CLI version of PHP. I’m much more familiar with the PHP language than I am with tools like Perl.
(2) The script uses the knowledge that I name my iPhoto Libraries according to the form “iPhoto-Library-20030521”, so that the last entry in a directory listing is the currently used Library (and the one whose size should be calculated).
(3) I’ve removed the ?> PHP delimiters from the script example, to prevent execution when you view it (since my blog is parsed by PHP).
The path less traveled.
