ruby

Ruby is a popular and powerful scripting language often used for command line tools. It was created in the mid-1990s by Yukihiro "Matz" Matsumoto. The Ruby programming language is known for its simplicity and readability, focusing on programmer happiness. Ruby command line tools are often used for automating tasks, manipulating data, and building interactive command line interfaces.

To create a command line tool in Ruby, you typically write a Ruby program with the necessary functionality and then use Ruby's built-in command line arguments support to accept input from the user. Ruby provides several built-in libraries and gems that can further enhance the command line tool capabilities, such as "optparse" for parsing command line options and arguments or "colorize" gem for adding colors to the output.

Ruby command line tools can interact with the file system, read and write files, consume APIs, and perform complex data processing. They can handle input and output streams, making them flexible for various data input sources and output destinations. Ruby's object-oriented nature allows for creating modular and reusable code, making command line tools maintainable and extensible.

Command line tools written in Ruby are cross-platform compatible, allowing them to run on different operating systems, including Linux, macOS, and Windows. Ruby's community is vibrant and supportive, offering a wealth of resources, tutorials, and libraries to aid in building command line tools. With its rich ecosystem, Ruby provides developers with a variety of tools and frameworks to expedite the development process and increases productivity.

Overall, Ruby provides an excellent platform for building command line tools that are simple, expressive, maintainable, and powerful enough to handle various tasks and processes efficiently.
