Unique list

[Lance Prais]

I would like to create a unique list.  For example, I have two separate
lists of solution ids and there is the potential of over lapping results.
How would I best eliminate the duplicates and have a unique list of results.
Does anyone have an example of some code they used to do this?

I am trying to use the following code but is not working, just hoping
someone has a better way to do this.
sub createUniquePartitionFile {
        my %args = (
                PARTITION => '',
                PARTITIONFILE => '',
                OUTPUTFILENAME => '',
                @_,
        );
        $status = 0;
        $partitionFile = $args{PARTITIONFILE};
        $outputFileName = $args{OUTPUTFILENAME};
        # Message
        print "topten: Creating a unique solution file for [$partition].\n";
        # Remove existing output file
        $command_string = "/usr/bin/rm -f " . $outputFileName;
        $status = `$command_string`;

        $command_string = "sort -u " . $partitionFile . " \> " . $outputFileName;
        $status = `$command_string`;

        return  $status;
}

Thank you in advance
