# This is a basic example how to create an import from csv data. This could 
# be called in a rake task:

namespace :db do
  namespace :import do
    desc "Import customer of old shop from csv"
    task :customer => :environment do
      csv_file = 'db/customer_data.csv'
      importer = Import::ImportCustomer.new(IO.read(csv_file))
      importer.import

Launch Sublime Text 2 from the Mac OS X Terminal

Sublime Text 2 ships with a CLI called subl (why not "sublime", go figure). This utility is hidden in the following folder (assuming you installed Sublime in /Applications like normal folk. If this following line opens Sublime Text for you, then bingo, you're ready.

open /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl

You can find more (official) details about subl here: http://www.sublimetext.com/docs/2/osx_command_line.html
