Ruby Language Getting started with Ruby Language Hello World from IRB
Example
Alternatively, you can use the Interactive Ruby Shell (IRB) to immediately execute the Ruby statements you previously wrote in the Ruby file.
Start an IRB session by typing:
$ irb
Then enter the following command:
puts "Hello World"
This results in the following console output (including newline):
Hello World
If you don't want to start a new line, you can use print:
print "Hello World"
