What permissions are you trying to add/take away?  Much of this is done 
by editing which group or groups a user is part of.  Other times you 
will need to change the files that a user can read/write/execute.  If 
you give us an example of what a user [can/can't] do and what you want 
that user to be [unable/able] to do we can offer more help.

To be or not to be, that is the question
                2b || !2b
(0b10)*(0b1100010) || !(0b10)*(0b1100010)
        0b11000100 || !0b11000100
        0b11000100 || 0b00111011
               0b11111111
        255, that is the answer.
