Extract first line of pdf file and put as title

[JpPamplona]

Hello guys,

is there a way of getting the first line of many pdf files and put it as theirs title metadata?

Thanks!

Sorry, ExifTool doesn't have the ability to decode the displayed content of a PDF document.

Exiftool can't do this, but with a little bit of regular expression and scripting magic, perhaps you can achieve what you want to do with e.g. ps2ascii (tool to extract text from a PDF, part of Ghostscript). I use this to automatically move some PDFs I receive regularly to a dedicated folder on my system.
