    That's about the only easy thing you can do with a PDF (aside from unlink()). Here's how to get a page count.

    use PDF::API2;


my $pdf = PDF::API2->open( 'yourfile.pdf' );
my $count = $pdf->pages();
print "O frabjous day! The PDF has $count pages.  Callooh! Callay!\n";

    PDF::API2

    Update: Well, in my excitement, having just done some painful work with PDF's a few days ago, I jumped on an answer, not realizing that you (the OP) followed up to your own node with a mostly similar solution. ...except that yours keeps a running total of total pages across multiple PDF files. I didn't see that need in the original question. But now I'm wondering what just happened here: If you already know the answer why did you post the question to Seekers of Perl Wisdom. Is there something more you would like us to add to your solution? :)

    Install xpdf. Run the pdfinfo utility on the pdf you want. Read its output. It has a line like Pages: 150 which should give you the number of pages.

    We can do like this..

    use PDF::API2;
    foreach $doc (@ARGV)
    {
    $pdf = PDF::API2->open($doc);
    $pages = $pdf->pages;
    $totalpages += $pages;
    print "$doc contains $pages pages\n";
    }
    print "Total pages of pdf pages = $totalpages\n";

    You could install pdftk for your platform and then use:

    pdftk <filename> dump_data

    It will emit 11 lines of metadata about the file. The last item is the page count.
