Hello monks.

I have the following data structure via data dumper:

$VAR1 = {
          'CSTRING' => 'public',
          'SPECIFIC' => '1',
          'GENERIC' => '6',
          'SSERVER' => 'test1',
          'DATE' => 'Wed Feb 26 11:46:00 2003',
          'OID' => '1.2.3.4.6',
          'DEVICE' => '123.124.125.126',
          'TRAPS' => {
                       'TRAP_LIST' => [
                                        {
                                          'TYPE' => 2,
                                          'DATA' => '5',
                                          'VARBIND' => '1.1.2.5.26'
                                        }
                                      ]
                     },
          'PORT' => '162'
        };
$VAR2 = $VAR1;
$VAR3 = {
          'CSTRING' => 'public',
          'SPECIFIC' => '0',
          'GENERIC' => '3',
          'SSERVER' => 'test1',
          'DATE' => 'Wed Feb 26 11:13:11 2003',
          'OID' => '1.3.6.1.4',
          'DEVICE' => '124.125.126.128',
          'TRAPS' => {
                       'TRAP_LIST' => [
                                        {
                                          'TYPE' => '2',
                                          'DATA' => '12',
                                          'VARBIND' => '1.3.6.1.2.1.2.
+1.1'
                                        },
                                        {
                                          'TYPE' => '2',
                                          'DATA' => '20',
                                          'VARBIND' => '1.3.6.1.2.1.2.
+1.1'
                                        },
                                        {
                                          'TYPE' => '2',
                                          'DATA' => '22',
                                          'VARBIND' => '1.3.6.1.2.1.2.
+1.7'
                                        },
                                        {
                                          'TYPE' => '2',
                                          'DATA' => '32',
                                          'VARBIND' => '1.3.6.1.2.1.2.
+1.8'
                                        }
                                      ]
                     },
          'PORT' => '162'
        };

How can I get rid of $var2 = $var1?
or even better how can I check for that to prevent it?

This is the code that generates the above

my @temp = ();
    
    foreach (@log_file) {
    chomp;
    
    next if ($_ =~ /^\s*$/);

    if ($_ =~ /^Date:\s+(.+)$/) {
        push(@temp, $hash) if (defined($hash));
        $hash = {DATE => $1};
    }
    if ($_ =~ /^SServer:\s+(.+)$/) {
        $hash->{SSERVER} = $1;
    }
    elsif ($_ =~ /^Device:\s+(.+)$/) {
        $hash->{DEVICE} = $1;
    }
    elsif ($_ =~ /^CString:\s+(.+)$/) {
        $hash->{CSTRING} = $1;
    }
    elsif ($_ =~ /^Port:\s+(.+)$/) {
        $hash->{PORT} = $1;
    }
    elsif ($_ =~ /^SNMP Traps Generated:/) {
        $hash->{TRAPS} = {TRAP_LIST => []};
    }
    elsif ($_ =~ /^\s+Trap OID:\s+(.+)$/) {
        $hash->{OID} = $1;
    }
    elsif ($_ =~ /^\s+Generic:\s+(.+)$/) {
        $hash->{GENERIC} = $1;
    }
    elsif ($_ =~ /^\s+Specific:\s+(.+)$/) {
        $hash->{SPECIFIC} = $1;
    }
    elsif ($_ =~ /^\s+Varbind:\s+(.+)$/) {
        $trap = {VARBIND => $1};
    }
    elsif ($_ =~ /^\s+Type:\s+(.+)$/) {
        $trap->{TYPE} = $1;
    }
    elsif ($_ =~ /^\s+Data:\s+(.+)$/) {
        $trap->{DATA} = $1;
        push(@{$hash->{TRAPS}->{TRAP_LIST}}, $trap);
    }
    }

    push (@temp, $hash); # if (defined($hash));
    push @lookup, @temp;

I only run into this problem when @lookup has data prior to running this sub-routine.
Any ideas?
