Here’s something I am wondering if/how Hazel can do. In my work as a trial court judge, I often create multiple scheduling orders using Word and Excel to create a mail merge document as a PDF file. I then separate the individual orders by dragging the two pages in the order to the desktop. What I’d love Hazel to do is to “read” the contents, identify the case number in the order and then rename the file to match that case number. To be specific, near the top of each page in the caption (Party A vs. Party B) there will be a case number like 1906 PL 501. The next PDF might be 1906 PL 609. As I drop the new PDF file containing only 1906 PL 501 into the Hazel-monitored folder, I’d want Hazel to rename the file to 1906 PL 501 (or whatever the case number happens to be).
Something like this could be useful for anyone who might want to rename PDF files based on say an author’s name for academic articles etc.
I’ve hunted around but can’t seem to find any examples. The AppleScript stokini uses looks like it could be a start, but I could write everything I know about AppleScript inside a matchbook cover. 
Ideally I’d like to find a resource online that can show me how to do it so I learn something. Then if I run into problems I could ask questions on this site.
Many thanks in advance!
