Creating a new command

Follow the instructions below to create a new command

1. Create a new file in the commands directory named my-command.rb
2. Do your work in my-command.rb. This file should be in a similar format to below (it must contain an execute function and an options function):

   module GHI
     module Commands
       class MyCommand < Command
   
         def options
             OptionParser.new do |opts|
                 opts.banner = 'usage: ghi mycommand'
                 opts.on '-a', '--all', 'some flag information' do
                     object[:key] = 'value'
                 end
             end
         end
   
         def execute
             begin
                 options.parse! args
                 @repo ||= ARGV[0] if ARGV.one?
             rescue OptionParser::InvalidOption => e
                 fallback.parse! e.args
                 retry
             end
             puts "Hello, world!"
         end
   
       end
     end
   end  

3. Add your new file to the build manifest in the Rakefile
