$ ruby quicksort.rb unsorted.txt

quicksort.rb is the ruby file I would like to run unsorted.txt is the input file that contains unsorted numbers. Is it possible to do something like this in ruby?

Answer 1

You can read the commandline arguments and do a file operation. to read arguments you can use

ARGV.each do|a|
  puts "Argument: #{a}"
end

This way you can get the filename and get the content.
