You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: enum_connections.rb
    path of file: ./repos/metasploit-framework/modules/post/linux/busybox
    
    the code of the file until where you have to start completion: ##
# This module requires Metasploit: https://metasploit.com/download
# Current source: https://github.com/rapid7/metasploit-framework
##

class MetasploitModule < Msf::Post
  include Msf::Post::File
  include Msf::Post::Linux
    
  def read_connection_file(file)
    str_file = read_file(file)
    vprint_line(str_file)
    p = store_loot('busybox.enum.connections', 'text/plain', session, str_file, file, 'BusyBox Device Network Established Connections')
    print_good("Connections saved to #{p}")
  rescue EOFError
    print_error("Nothing read from file #{file}, file may be empty")
  end
