Possible? Giving and removing permissions via command/sign

Hello everyone and thank you for taking time to help me with a question of mine. I'm just wondering if it is possible, if so how, to give a player a permission or remove a permission without changing the group they are currently in via command or a sign.

Thanks,
Warreo

 

you can do it just using commands if you have PermissionsEX

 

Pseudo code:
PlayerInteract event
Player p = event.getPlayer:
If interact is right click
If its a sign
If sign text is "right click to get Op!!1!"
Dispatch command: "pex user "+p+" add permission.node"

Also: the dispatch command thing is


Code:
plugin.getServer().dispatchCommand(console,"command plus arguments");

I think I understand what your saying. And thank you very much, it helps a ton. And the

plugin.getServer().dispatchCommand(console,"command plus arguments");

should work with any command to give a player a permission using PermissionsEx, correct?

 

Yes. It works with any command, but it executes it from the console, so you can't do stuff like /fly

 

Thank you very much! I've been doing some testing and this helps soooo much! makes my life a million times easier! my server appreciates it!

 

No problem!
