Add permission to a player when typing a command

So this is my code, when typing for example "/perm add Notch" it would give player Notch a certain permission, in this case "essentials.helpop". What's the expression I should use to do this? something similar to the this?:

Code:

getServer().getPluginManager().addPermission(new Permission("essentials.helpop"));

Code:

if(args.length == 2 && args[0].equalsIgnoreCase("add")) {
       Player tp = (Player) Bukkit.getServer().getPlayer(args[1]);
       if(tp != null) {
             //command to add permission to a "tp"
       }
return false;
}

 

Check out this tutorial, it explains the basics of how to work with them: http://wiki.bukkit.org/Developing_a_permissions_plugin

You can also try using the Vault API.

 

Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "permission command here");

"Permission command here" is where you put pex + player + "permission"

 

@Treeline1 He wants to do it programmatically.

 

@Treeline1 And when you do it like this, it would screw up all Commands which require a Player as Executor (such as the /tp Command, because how do you wanna teleport a Console?) so that's a very bad Idea.

 

If he was using a permissions plugin like Permissionsex or whatever, then this command gives them the permission to be able to teleport. Which is what I thought he was asking for
