As per Google Analytics, the article "How do I make a command-line tool in Ruby?" has been the most popular this year

Please also note that highline makes many tasks such as user input simple. There’s main and Vision Commander and gli also. There is a tiny wrapper over OptionParser called subcommand (a ruby gem) which allows for commands within our program. All option parser syntax will continue to work. Why i prefer “subcommand” is that all the others take over the application. subcommand prints help for all options, and subcommands and their options too. I am glad you did not get into the many alternatives for OptionParser, I’ve tried them all and come back to OptionParser in the end. There are many other aspects of command-line programs that need to be mentioned. For example, return values (0 and 1), so the program can be called from a script. Also, the program should be usable in pipes, so it can work with other programs just like any other unix script. Thanks, rahul
