Frankly, I would not use a regexp for this (untested) :

my %opts;
undef @opts{ qw|-config -files -params -driverPath 
   -appPath -batchPath NONE| };
my %seen;
for my $e (split /,/ $str) {
   print "BAD op: $e\n" unless exists $opts{$e};
   print "Duplicate: $e\n" if $seen{$e};
   print "Incompatible with NONE\n" if $seen{NONE} && scalar keys %see
+n > 1;
   $seen{$e};
}
