Hello all
I'm working on a print quota script that parses through a file to be printed to grab page numbers, paper size, and some others. My method works fine on jobs of small size, but takes forever on larger jobs. Is there a faster way to parse through a 60+ MB file? My method is thus: 
        open FILE, "$opt{d}/dfA$opt{j}$opt{h}" || die "cannot open $op
+t{d}/dfA$opt{j}$opt{h}: $!\n";
        while (<FILE>){
                                                                      
+                                                                     
+      
            # Duplex or no...
            $pagestate = "Duplex" if (/^%%.* \*Duplex Duplex.*/ || /^[
+&l1S/ig || /^[&l2S/ig || /DUPLEX=ON/g);
            $pagestate = "Simplex" if (/^%%.* \*Duplex None.*/ || /^[&
+l1S/ig || /DUPLEX=OFF/g);
                                                                      
+                                                                     
+      
            # Page Size
            $pagesize = "Letter" if (/^%%.* Letter/ || /^[&l2A/ig || /
+PAPER=LETTER/g);
            $pagesize = "Legal" if (/^%%.* Legal/ || /^[L3A/ig || /PAP
+ER=LEGAL/g);
            $pagesize = "Tabloid" if (/^%%.* Tabloid/ || /^[&l2000A/ig
+ || /PAPER=LEDGER/g);
                                                                      
+                                                                     
+      
            # Number of Pages
            #
            # Possible postscript flags are:
            # %%Pages: #
            # %%Page: # #^M
            # (%%[Page: #]%%) = ^M
            $pages = $1 if (/^\(?%%Page\w?: \d+? ?(\d+).*?/);
                                                                      
+                                                                     
+      
            # Number of copies
            $copies = $1 if (/^%%.* numcopies (\d+).*?/i);
            $copies = $1 if (/.*QTY=(\d+).*?/);
                                                                      
+                                                                     
+      
            # Document Title
            $doctitle = $1 if (/^%%Title: (.*)$/);
            chomp $doctitle;
        }
        close FILE;

The above grabs postscript and pcl flags for me, but it can be dirt slow. Anyone have any suggestions?

Thanks much!
Louie
