Five Ruby Hello World greetings. The the following Hello World examples in the Ruby programming language may we want the ARGV array — where Ruby stores
class OptionParser The following example is a complete Ruby program. Parses command line arguments argv in order.
How do I make a command-line tool in Ruby? This guest post is by Allen Wei, who works as Senior Ruby On Rails Engineer for Seravia, in Beijing.
OptionParser - Ruby 2.1.1 verbose] = v end end. parse! p options p ARGV Complete example The following example is a complete Ruby program.
A Short Explanation of ARGV. Ruby captures all the command line arguments passed to a Ruby program Let's take a look at a real world example,
Here are a few examples. 1) To work with the actual values of the arguments that are passed into your Ruby program, just treat ARGV as a normal Ruby array,
Example of embedding Ruby interpreter into C/C++ program Raw. main.cpp // very basic embedded Ruby interpreter for C++ programs // thrown &argv); RUBY_INIT_STACK;
Reading from input files or STDIN in Ruby using ARGF. If ARGV is empty, For example, a cat-like program could be implemented in Ruby as:
Ruby Example Code CSc 232 Ruby: Basics: Ruby Hello, World! Expressions: Oh, I Meant Objects: Strings: String Operations
ARGV is used for storing arguments passed into a ruby program. For instance is I execute my ruby file like so [code]ruby foo.rb bar baz[/code] Then [code]ARG
For example, an alternative entry point in Apple I's BASIC The "argc" variable keeps the number of arguments passed to the program. The "argv" variable Ruby

Any command-line arguments after the program filename are available to your Ruby program in the global array ARGV. For instance, invoking Ruby as
