Concatenation
- Good discussion of various ways, and a bash/TeX script too
- mbtPDFasm - swiss army knife for PDFs with a terrible name :-) So far doesn't seem to work with all PDF's
Rearranging pages
If one pdf contains left-side pages of a scanned book, and another contains the right-side pages, here's one way to fix it using PDFTK:
genranges.scm: (define lastpage 269) (let loop ([i 0]) (when (<= i lastpage) (printf " A~a B~a" i i) (loop (+ 1 i)))) (exit) csi genranges.scm > r vi r (and delete extraneous stuff) pdftk A=left.pdf B=right.pdf cat `cat r` output c.pdf
