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).
