i am a complete noobie here to Ruby and programming in general.
I was looking for the best way to break a loop using "user input" via
gets.
I have a loop running that needs to be broken when the user hits a
specified key.
What would be the best way to go about this?
Thank your for your time and attention and sorry for such a "noobie"
question!

There is no best way, here are 2 ways to mull over, first way gives you an idea of how to break out of a loop. The 2ns way show use of a do/while loop, that test for the loop condition is done at the end, not the start.

Be aware that pressing Ctrl-D (Unix) makes gets return nil, not a
string.
while(true)
c = gets
break if c.chomp == 'x'
end
loop do
c = gets
break if not c or c.chomp == 'x'
end
begin
c = gets.chomp
end while c != 'x
begin
c = gets.to_s.chomp
end while c != 'x
