Alternative of pdfinfo to display author and title

pdf

I am using pdfinfo to display the title name and author of pdf files. But for some pdf files, it's not working. It's showing all other info like creation date,modification date,pagesize etc except title of the paper and authors name. Is there any alternative way to retrieve these info? I have used:

pdfinfo filename

For pdfinfo to display the title, it must be specified in the metadata field title. The title that it displays it's not the pdf "physical" filename if that is what you're trying to get.

Use a graphic explorer to view the file properties and in the metadata tab make sure you have a title. In the image bellow you can see that they can have different values

Edit: For an alternative to pdfinfo you can use exiftool to read/write files metadata. For example to get title and author you could do this:

exiftool -Title -Author input.pdf

Possible to extract title and pagenum of each page in a pdf file

The following script will print the first line of each page of the PDF file passed as argument, followed by a space and the line number... It uses tools from Poppler (package poppler-utils on Debian or Ubuntu).

#!/bin/bash
if="$1"
pages=$(pdfinfo "$if" | sed -nre 's/^Pages: +([0-9]+)$/\1/p')
for ((i=1; i<=$pages; i++)) ;do
    printf "%s %d\n" "$(pdftotext -f $i -l $i -layout "$if" - | head -n 1)" $i
done

Export terminal display to PDF

I would try writing the syntax-highlighted code as an HTML file, using the Vim Syntax->Convert to HTML menu option. Then open the HTML in a browser and print to a PDF file. You can of course edit the HTML if you want to show just a section of the code, or use pdfcrop to isolate the region of interest.
