So, following up on the previous thread about using pdftk to rotate pdf's, here is a follow-up for those times you need to get a single page of a range of pages from a larger PDF document.
First, install pdftk:
$ sudo apt-get install pdftk
For example, to extract pages 22-36 from a 100-page PDF file using pdftk:
$ pdftk A=100p-inputfile.pdf cat A22-36 output outfile_p22-p36.pdf
When you invariably need to put them back into a single large document again, just:
$ pdftk in1.pdf in2.pdf cat output out1.pdf
To more fun ways you can use pdftk, check out the website examples page.
