How to add page numbers to Postscript/PDF

Question

If you\'ve got a large document (500 pages+) in Postscript and want to add page numbers, does anyone know how to do this?

Answer 1

I took captaincomic's solution and added support for filenames containing spaces, plus giving some more informations about the progress

#!/bin/bash
clear
echo
echo This skript adds pagenumbers to a given .pdf file.
echo 
echo This skript needs the packages pdftk and enscript
echo if not installed the script will fail.
echo use the command sudo apt-get install pdftk enscript
echo to install.
echo 
input="$1"
output="${1%.pdf}-header.pdf"
echo input file is $input
echo output file will be $output
echo 
pagenum=$(pdftk "$input" dump_data | grep "NumberOfPages" | cut -d":" -f2)
enscript -L1 --header='||Page $% of $=' --output - < <(for i in $(seq "$pagenum"); do echo; done) | ps2pdf - | pdftk "$input" multistamp - output "$output"
echo done.
