call R function with parameter from cmd

Question

I have file a.R with one function:

  big_name<-function(name){
    big_name<-toupper(toString(name))
    return(big_name)
  }

How can I call this function from cmd(command prompt or shell) with parameter for example "John", without R opening?

You can do : R -e "source('./big_name.R'); big_name('test')" If you added R in your system path.
