   Save the file, then 'chmod o+x thefile"   
      
     chmod --> change mode (permission) bits   
     o+x --> for "o"wner, set the e"x"ecute bit   
     thefile --> just a placeholder for the filename you saved it as

   Because the okular (the last part of that pipeline) was still running.

   you'll need to read the qpdfview manual to determine what switch (if   
   any) it needs to be told "read from stdin".   
      
   It may also be the case that you cannot pipe input into qpdfview (I know   
   evince has this shortcoming).

   Artifact of opening it from a pipeline.   
      
   If you want to save the output as a file, this is a little more   
   straightforward:   
      
     gunzip -c $(man -w WHATEVER) | groff -ktman -Tpdf > WHATEVER.pdf   
      
      
   Instead of sending the groff conversion output of the "WHATEVER" manpage   
   into okular, the above command stuffs it into the file "WHATEVER.pdf"   
   (then you can open it with whatever viewer you want).
