There are easier ways to do certain parts of your existing program. If you want to find all gzip'd files in a directory, use File::Find: 
use File::Find;
my $dir = "/home/lprjob1/filest"
find( sub { push @files, $File::Find::name if -f && /.+gz/ }, $dir );

Then I would look into using some of the CPAN modules associated with gzip like Tie::Gzip. If the files you are looking to process are text files, you can tie them to a gzip'd filehandle and read them: 

use Tie::Gzip;
 for my $log (@files) {
   tie *LOG, 'Tie::Gzip';
   open (\*LOG, '<', "$log") or die("Cannot open $log: $!");
   while (my $line = <LOG>) {
     # Iterate over the files here and do blah
   }
   close (LOG);
   untie *LOG;
 }
