I am trying to write qpdf output to stdout.

qpdf --empty --pages 1.pdf 1 2.pdf 2 -- /dev/stdout

But it says open /dev/stdout: Permission denied.

Why qpdf can not write the output to stdout? Does it require random access in the output file to successfully write the output? Thanks.

pdftk can write output to stdout. I don't see a reason why qpdf can not do so. – user1424739 Feb 20 '23 at 19:28
`/dev/stdout` is not of what? The last sentence was not complete. I don't know what you are trying to say. – user1424739 Feb 21 '23 at 03:27

OK. `-` works. ----- – user1424739 Feb 23 '23 at 02:15
