Restricting to certain programs

Hello, im trying to restrict the fs.delete function so that it can only be used in specific programs.

local oldfsdelete = fs.delete
function fs.delete()
  --verify permision then if the program has permission run oldfsdelete
end

ive looked into using shell.getRunningProgram but i think that would just return the program directory of the above code.

any help is appriciated :)/>

It would not. It would return the file path of the program running at the time it is called.
