Q. How do I find out more information about Portable Document Format (PDF) document from a shell prompt? How do I find out information such as what software used to create a pdf file, its page size, and its creation date etc, using the terminal?


A.
You need to use pdfinfo command which, prints the contents of the 'Info' dictionary (plus some other useful information) from a Portable Document Format (PDF) file.

pdfinfo to view tech information about a pdf file

Type the command as follows:
$ pdfinfo {file.pdf}
$ pdfinfo lecture5.pdf
