Only show first letters of string of each word

I have this string

Rock Paper Shotgun

I have looked around to find an easy way to get the first letters of each word. Because I want my end result to be:

RPS

Is there a special ruby on rails function for this? If not, how can I achieve such thing?

I found this

str = "nishant nigam"
=> "nishant nigam"
str.split(" ").map {|name| name[0].chr }.join.upcase
=> "NN"

But I was hoping if there is even a simpler method

"Rock Paper Shotgun".split.map(&:first).join.upcase

edit:

irb: [4] pry(main)> "rock Paper Shotgun".split.map(&:first).join.upcase

=> "RPS"

Do it like this:

"Rock Paper Shotgun".split.map{|i| i[0,1].upcase}.join
