Hi, I have a very large Apache weblog. What I want to do is extract all the hits for each department's directory and put them in its own file. I thought of a couple of ways to do this, but none seem to be all that great. First idea was: 
my @dir_list = qw(dept1 dept2 dept3); # actually there are over 40 dep
+artments in this list

foreach my $dept (@dir_list) {

     open (DEPTLOG, "+>/data/logs/" . $dept . "current.log");

     open (LOGFILE, "/data/logs/access.log");

     while (<LOGFILE>) {

          if (/$dept/) {

          print DEPTLOG $_;

     }

close(LOGFILE);
close(DEPTLOG);


}

The other way I thought was to store each log in a hash first then wirte it to the DEPTLOG 
my @dir_list = qw(dept1 dept2 dept3); # actually there are over 40 dep
+artments in this list

my %logs;

open (LOGFILE, "/data/logs/access.log");

while (<LOGFILE>) {

     foreach my $dept (@dir_list) {

          if (/$dept/) {

          $logs{$dept} .= $_;

     }

}

close(LOGFILE);

foreach my $dept (@dir_list) {

     open (DEPTLOG, "+>/data/logs/" . $dept . "current.log");
     print DEPTLOG $logs{$dept};
     close (DEPTLOG);



}

As I said neither of these seem very good. They both take forever to process. Is there a quicker way to handle this? Thanks.
