How to tell what version of `pdftk` you're running?

Question

pdftk -v doesn't do the trick. Neither does pdftk -h. That just fills the screen past the available history with a manual. But it does not tell me what version I'm running.

Any ideas?

I'm running Windows.

Answer 1

On my WinXP (and Ubuntu) pdftk --version works just fine.
e.g. Ubuntu
