Execute saved Synaptic markings

It happens quite often that I use synaptic to manage packages on my debian.However, sometime I save the markings in order to perform the installations another time.For example I need to apt-get something quickly without waiting for the whole thing to be downloaded and installed.

The standard procedure would be running synaptic again and then loading the markings.However, in this cases I don't feel like I need to start the whole synaptic thing. I'd prefer a small command line utility that processes the saved markings.

I wrote one. It is very simple. It uses sudo, so every now and then it asks the password.Of course one could do a better job, but I had not time to do something better.

#!/usr/bin/env ruby

args = $*
if args.size == 0
    puts "You should provide a file to process"
    exit 0
end

dict = Hash.new
File.open(args[0]) do |f|
    f.each_line do |line|
        key, action = *line.split
        dict[key] = action
    end
end

# sudo apt-get #{v} #{k}

dict.each do |k, v|
    exec("sudo apt-get -y #{v} #{k}") if fork.nil?
    Process.wait
end
