How do You Pass Command Line Arguments in Ruby?
Command-Line Arguments:
When you run a Ruby program from the command line, you can pass in arguments. These are accessible in two different ways:
i. The array ARGV contains each of the arguments passed to the running program. Create a file called cmd_line.rb that contains the following:
puts "You gave #{ARGV.size} arguments" p ARGV
When we run it with arguments, we can see that they get passed in:
$ ruby cmd_line.rb ant bee cat dog
You gave 4 arguments
["ant", "bee", "cat", "dog"]
