OK, I am working on taking the CLI for an application we're using enterprise wide for our Ops folks and it's presented an interesting challenge: It takes values of the form: server_admin -u USER -p PASSWORD cmdName=addTargetServer hostname=host123 ipAddress=1.1.1.1 Though there's approximately 15 'cmdNames' with each able to have anywhere from 2-20 paramaters (hostname and ipAddress in this case). This screamed at first to be ideal to setup as hash values of the form: 
my %addTargetServer = ( hostName => "", ipAddress => "" );
    my %addTargetApplication = (targetServerHostName => $SERVER, targe
+tApplicationType => "Generic", targetApplicationName => "");
    my %addTargetAccount = ( targetServerHostName => $SERVER, targetAp
+plicationName => $addTargetApplication{targetApplicationName}, target
+ServerUserName => "", targetServerAccountPassword => "");

using Getopts::Long I defined appropriate --option tags for these and now I want to define which ones were actually defined from the command line: 
my $OPTIONS = GetOptions (
        'user=s'   => \$USERNAME,
        'passwd=s'  => \$PASSWORD,
        'server=s'  => \$SERVER,
        'hostname=s' => \$addTargetServer{hostName},
        'ipaddr=s'  => \$addTargetServer{ipAddress},
        'apptype=s' => \$addTargetApplication{targetApplicationType},
        'appname=s' => \$addTargetApplication{targetApplicationName},
        'targetuser=s'  => \$addTargetAccount{targetServerUserName},
        'targetpasswd=s' => \$addTargetAccount{targetServerAccountPass
+word}
);

So now I have defined values in the key pair for a given HASh, but I need to know which cmdName (which in this case is the actual name of the HASH I defined i.e. 'addTargetApplication' or somesuch, but I can't for the life of me now figure out how to get the ACTUAL NAME of said hash for passing to the cmdName parameter in the vendors tool? Any ideas welcome...
