Is there something I can use that renames PDF files according to their content? Basically an equivalent of http://macscripter.net/viewtopic.php?id=27620 in Ubuntu.
If you are comfortable with python you could use the script on http://blog.matt-swain.com/post/25650072381/a-lightweight-xmp-parser-for-extracting-pdf-metadata-in. I have just tested the scripts he provides (for a start, you can pip install pdfminer) and they work nicely. The result they give is something along the lines of:
[{'ModDate': "D:20050422142709+02'00'", 'CreationDate': "D:20050422142709+02'00'", 'Producer': 'Mac OS X 10.3.8 Quartz PDFContext', 'Creator': 'Word'}]
That output you could use to rename your files.
