CLI pdf viewer for linux [closed]

Question

Hey, for quite a while now, I am looking for a pdf viewer for the command line.

As I like to work without X on Linux, and often work on a remote machine, I would like to have a tool to read pdfs. There are quite a lot of really good graphical programs (evince, okular, acroread, ...) to do the job, so I figured there should be at least one decent text-mode tool. But I don't even know of a crappy one!

Currently, I either start X only to read pdfs, or use pdftohtml+lynx. However, the latter does not produce a very good output, and most documents are just unreadable, especially if they contain mathematical formula.

Google is full of people saying either it's not possible or suggesting the pdftohtml version.

I realise, this is not exactly a programming question, but I am currently considering starting a project to implement such a program, unless there already is a good one out there.

Thanks for any suggestions.

Answer 1

Hi I think that you don't need to write a program for your purpose I mean reading pdf file in console mode because "less" command already do it for you. So use it and just enjoy it.

less "the name of pdf file"

Answer 2

Ok, you asked to know even "crappy" ones. Here are two (decide yourself about their respective crappiness):

First: Ghostscript's txtwrite output device

 gs \
   -dBATCH \
   -dNOPAUSE \
   -sDEVICE=txtwrite \
   -sOutputFile=- \
   /path/to/your/pdf

Second: XPDF's pdftotext CLI utility (better than Ghostscript):

 pdftotext \
   -f 13 \
   -l 17 \
   -layout \
   -opw supersecret \
   -upw secret \
   -eol unix \
   -nopgbrk \
   /path/to/your/pdf
   - |less

This will display the page range 13 (first page) to 17 (last page), preserve the layout of a double-password protected named PDF file (using user and owner passwords secret and supersecret), with Unix EOL convention, but without inserting pagebreaks between PDF pages, piped through less...

pdftotext -h displays all available commandline options.

Of course, both tools only work for the text parts of PDFs (if they have any). Oh, and mathematical formula also won't work too well... ;-)

Edit: I had mis-typed the command above (originally using pdftops instead of pdftotext).

Answer 3

By the way, i m always in the same situation, and I use mc (midnight commander) which handles text pdf's very well... Just view the file (F3) in mc

Answer 4

fbgs maybe could do the trick.

Answer 5

There is also the green PDF viewer. There is a demo on YouTube.

Answer 6

fbpdf is a framebuffer pdf viewer.

There is also a fork, jfbpdf, but at the moment I am not able to get it working.

Answer 7

This would only work if your PDF document is structured, i.e. it is a tagged PDF document.

This is required to get the correct reading-order of the text objects in the document.

Tagged PDF documents also allow your to re-flow the document though I am not aware of any tool doing that with command line output.
