I'm running Kubuntu 18.04. I want to extract page 10 from a PDF file in the form of another PDF file. The program qpdf is supposed to do that. When I run the command
qpdf 0092434747.pdf --pages . 10 -- - > mtg.pdf
it seems to do the extraction, but there's no output; the file mtg.pdf is not created. I get the same result with (the more straightforward command)
qpdf 0092434747.pdf --pages . 10 -- mtg.pdf
What am I missing?
