Splitting a PDF with Ghostscript

Question

I try to split a multipage PDF with Ghostscript, and I found the same solution on more sites and even on ghostscript.com, namely:

gs -sDEVICE=pdfwrite -dSAFER -o outname.%d.pdf input.pdf 

But it seems not working for me, because it produces one file, with all pages, and with the name outname.1.pdf.

When I add the start and end pages, then it is working fine, but I want it to work without knowing those parameters.

In the gs-devel archive, I found a solution for this: http://ghostscript.com/pipermail/gs-devel/2009-April/008310.html -- but I feel like doing it without pdf_info.

When I use a different device, for example pswrite, but same parameters, it works correctly, producing as many ps files, as my input.pdf contains.

Is this normal when using pdfwrite? Am I doing something wrong?

Answer 1

I found this script wriiten by Mr Weimer super useful:

#!/bin/sh # # pdfsplit [input.pdf] [first_page] [last_page] [output.pdf]  # # Example: pdfsplit big_file.pdf 10 20 pages_ten_to_twenty.pdf # # written by: Westley Weimer, Wed Mar 19 17:58:09 EDT 2008 # # The trick: ghostscript (gs) will do PDF splitting for you, it's just not # obvious and the required defines are not listed in the manual page.   if [ $# -lt 4 ]  then         echo "Usage: pdfsplit input.pdf first_page last_page output.pdf"         exit 1 fi gs -dNOPAUSE -dQUIET -dBATCH -sOutputFile="$4" -dFirstPage=$2 -dLastPage=$3 -sDEVICE=pdfwrite "$1"

save it as pdfsplit.sh, see the magic happens.

PDFSAM also could do the job. Available on Windows and Mac.
