Hi Russell -
It's not often I have to assemble larger numbered documents. I usually use this little script.
enscript -L1 -F --header-font=Times-Roman12 -b '||$%' -o- < <(for i in $(seq "$(pdftk "$1" dump_data | grep "Num" | cut -d":" -f2)"); do echo; done) | ps2pdf - | pdftk "$1" multistamp - output "${1%.pdf}-numbered.pdf"
I've used something similar myself many times. Your grep command should be: grep '^PageMediaNumber:' as you're also matching 'PageLabelNumStyle' content. These aren't numeric values, and will cause seq to fail. It may also be possible for PageMediaNumber to return something like '1-1'. Personally, I'd use pdfinfo rather than pdftk … dump_data to do page counts, as its Pages field is always numeric. Bates Numbering is fun! cheers, Stewart
