${unique; 1,2,3,1,2; 1,2,4 } ~ “2,4,3,1”static String _uniqHelp = "${uniq;<list> ...}";
public String _uniq(String args[]) {
verifyCommand(args, _uniqHelp, null, 1, Integer.MAX_VALUE);
Set<String> set = new LinkedHashSet<String>();
for (int i = 1; i < args.length; i++) {
Processor.split(args[i], set);
}
return Processor.join(set, ",");
