I'm new with Perl, first time trying to use command line arguments and options. I want to provide the user with the options if you say "--help" : the "usage" comes up (doesn't run script) "--delete" : delete old files "--error" : print errors in log file then it will have 3 arguments so the command line would look like this:

learning_perl/script > program.pl --help --delete --err_dup F68 F100 5

this is my code for getting the command line but when I run this, I get an error and I know it has to do with the %options hash, but I'm not quite sure how to fix it 


sub getCmndArg {
    
#    my $num_args = $#ARGV + 1;
#    if ($num_args != 3) {
#        print "\nUsage: csv_ext_utl -d begin_addr end_addr numberOfSi
+ms\n";
#        exit;
#    }

    my %options=();
    GetOptions(\%options, qw[ help dfiles err_dup ]);

    if ($options{"help"}){
        print "help is called - Help Panel:\n";
    } else {
        print "help is NOT called\n";
    }


    if ($options{"dfiles"}){
        print "dfiles is called - deleting old simulation files\n";
        my $unlinked = unlink glob {"address_register_sweep_*.sv"};
    } else {
        print "dfiles NOT called\n";
    }
    
    if ($options{"err_dup"}){
        print "err_dup is called\n";
    } else {
        print "err_dup NOT called\n";
    }

    

    #$deleteFile = $ARGV[0];
    $beginAddrHex     = $ARGV[0];
    $endAddrHex     = $ARGV[1];
    $numberOfSims     = $ARGV[2];
}

Error I receive: 

help is called - Help Panel:
dfiles is called - deleting old simulation files
Odd number of elements in anonymous hash at ./csv_ext_utl line 90 (#1)
    (W misc) You specified an odd number of elements to initialize a h
+ash,
    which is odd, because hashes come in key/value pairs.

err_dup NOT called

If anyone can chime in, I'd appreciate it! Thank you!
