require ‘optparse’

options = {}

optparse = OptionParser.new do|opts|  
opts.banner = “Usage: file1 file2 …”  
opts.on( ‘-r’, ‘–hhhh’, ‘screen’ ) do  
puts opts  
end

opts.on( ‘-s’, ‘–ssss’, ‘Display this screen’ ) do  
puts opts  
end

opts.parse!  
end

# ======= ning@ning:~$ ruby xb.rb -h Usage: file1 file2 … -r, --hhhh screen -s, --ssss Display this screen

Someone else defined it for you

11:17:16 desktop$ ruby19 -r optparse -e ’ OptionParser.new.parse “-h”’  
Usage: -e [options]  
11:17:42 desktop$ ruby19 -r optparse -e ’ OptionParser.new.parse “-x”’  
-e:1:in `': invalid option: -x (OptionParser::InvalidOption)

Kind regards
