Hi All,

Whats the easiest way to remove duplicate entries from an array. Below is a
script that removes ip addresses from a log file and adds them to an array.
I then check the array to see if the value is already present and if it is i
set a flag($exists) and then push that value into the array if $exists is
false.

Is there an easier way? 

_____________START_____________

open(ADD_FIRE,"+</var/log/add_firewall") || die "Unable to open file\n";

open(LOG,"/var/log/testlog") || die "Unable to open file\n";

        while(<LOG>) {
                chomp;
                        $exists = 0;

                if(/\[(\d+\.\d+\.\d+\.\d+)\].+reject=550/) {
                $address = $1;
                        foreach(@ipadds) {
                                $exists = 1 if($_ eq $address);

}
                push(@ipadds,$address) if !$exists;

}
}
close(LOG);
close(ADD_FIRE);

        foreach(@ipadds) {
        print "$_\n";
}
