you can use gsub to replace something in a centain word or sentence, let say the players name for roleplay servers;

local name = "angelica_mitten":gsub ( "_", " " ) 

This will replace _ with a space, transforming Angelica_Mitten into Angelica Mitten. You can use this as a bad word filter too. read all about it on the lua wiki; http://lua-users.org/wiki/StringLibraryTutorial

Firstly if i am going to change everyone's name entering the server if he has a "_" to "" then how can i even check if he has "_", secondly how to apply this example on many typing characters, for example if i want to avoid everyone from typing numbers in mainchat ?

[tosfera]

Well, the function itself already checks if there is a _ in the given string. So don't worry about that, you should rename players without the underscore. Just remove it while typing etc. To remove numbers you can use the parameter %W like this;

local name = name:gsub ( "%W", "" );

Well, actually i wanted if someone changing his nick to something that contains numbers then a gui shows telling him that he couldn't change his nick to that name. i wanted gsub to automatically change it without numbers

So, how to check the entered nick if it contains numbers or not(without changing it)

function containsNumber ( str ) 
    if str:find ( "%d" ) then 
        return true 
    end 
    return false 
end
