如何向像-v，-o這樣的ruby腳本提供標誌並相應地放置代碼？

Question

我已經創建了我想要與控制檯一些標誌運行一個Ruby腳本說，在與我從控制檯以文件名新文件控制檯和-o店輸出-v標誌打印輸出使用gets()

我的代碼具有以下結構：

puts "Enter filename to analyze:\n\n" 
filename = gets().chomp 
puts "Provide filename to store result in new text file:\n\n" 
output = gets().chomp 
filesize = File.size(filename) 
puts "File size in Bytes:\n#{filesize.to_i}\n" 
pagecontent = filesize - 20 
puts "\n\nData:\n#{pagecontent}\n\n" 
File.open(filename,'r') do |file| 
     #whole process with few do..end in between that I want to do in 2 different #ways. 
    #If I provide -v flag on console result of this code should be displayed on console 
    #and with -o flag it should be stored in file with filename provided on console #stored in output variable declared above 
end 
end
