From the terminal I would like to be access the data that is readable when right clicking on a pdf file and selecting "document". example
I have tried reading metadata with tools such as mminfo and pdftk but some files are password protected so they can't show me the meta data.
Help appreciated.
You can use the program
pdfinfo
from the packagepoppler-utils
. For font information you can usepdffonts
from the same package.
