Os ubuntu.
Need to get links or more data (for example binding layer from QuarkXPress application) from pdf to text, in terminal.
Tried pdftotext, but seems links are not exported, pdfgrep is the same.
Is there any solution?
Thanks.

You could try and extract the /URI(...) PDF directives by hand, maybe after removing compression if any using pdftk:
pdftk file.pdf output - uncompress | grep -aPo '/URI *\(\K[^)]*'

@StanislavHosek. OK. I think I misinterpreted your question and that you were wanting to retrieve the list of linked URLs from a PDF file. Jul 24, 2019 at 15:49
Using pdfx and filtering all lines starting with - http:
pdfx -v file.pdf | sed -n 's/^- \(http\)/\1/p'
Test this:
pdftotext -raw "filename.pdf" && file=`ls -tr | tail -1`; grep -E "https?://.*" "${file}" && rm "${file}"

1You should not parse
ls..., but you can just send output to stdout instead of using a temporary file:pdftotext -raw "filename.pdf" - | grep ...(Fromman pdftotext:If text-file is ´-', the text is sent to stdout.)– pLumoJul 24, 2019 at 14:29 -

pdftotext version 0.71.0 / GNU bash, versão 5.0.3(1)-release (x86_64-pc-linux-gnu) / grep (GNU grep) 3.3. @pLumo it works either way for me... :) Jul 24, 2019 at 20:07
You can use pdftohtml and then use lynx to pull the links from the html.
First, you need to check if your pdf is compressed or not, see:
How to know if a PDF file is compressed or not and to (un)compress it
If it's compressed, you need to uncompress it.
Then, you can extract links using grep and sed:
strings uncompressed.pdf | grep -Eo '/URI \(.*\)' | sed 's/^\/URI (//g; s/)$//g'
pdftohtml? it just works for me, maybe you could share a sample PDF file...pdfannotextractor
