Thanks for your report, era! Please note, that since pdftk 1.45 the syntax has changed. "Shorthands" are replaced by the full words [1]. The man pages and the official documentation have been updated, but maybe something was missed. Which documentation did you use? The man page on your system ("man pdftk") should be ok.
[1] From the 1.45 changelog ( https://www.pdflabs.com/docs/pdftk-version-history/ ): "Changed the syntax for page rotation. Instead of N, S, E, W, L, R and D, now use: north, south, east, west, left, right and down." ** Changed in: pdftk (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1385086 Title: Command-line rotation shorthands don't work (incl. man page examples) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pdftk/+bug/1385086/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
