pdf problem

[Harikrishna Charan]

Hi ,

     I have installed ghostscript version 7.04 on my linux machine. Now i am 
trying the page selection printing using the ghostscript. 

when I type gs <somefile.pdf> I am able to view the pdf file. But when try to 
redirect the output of the gs to some other file on the command line it gives 
error. 

On the command prompt I typed 
         gs -q -dNOPAUSE -sDEVICE=deskjet -sPAPAERSIZE=a4 -dFirstPage=2 
-dLastPage=10 -sOutputFile=Output -

and I got the following error.

 /ioerror in --setfileposition --

What's the possible cause for this 

If your provide solution it will be helpful.

thanks and Regards
charan
