simple Rake task for cleanup of Rails directory

admin-cleanup.rake

namespace :admin do
  desc "Clean up all temporary files in the application directory"
  task :cleanup, :needs => :environment do
    puts "Removing temporary directory contents"
    tmp_files = []
    %w{ cache pids sessions sockets }.each do |dir|
      tmp_files += Dir.glob( File.join(Rails.root, "tmp", dir, "*") )
    end
    File.delete(*tmp_files)

    puts "Removing log files"
    log_files = Dir.glob( File.join(Rails.root, "log", "*") )
    File.delete(*log_files)

    puts "Removing emacs temporary files"
    emacs_tmp_files = Dir.glob( File.join(Rails.root, "**", "*~") )
    emacs_tmp_files += Dir.glob( File.join(Rails.root, "**", "\#*\#") )
    File.delete(*emacs_tmp_files)
  end
end

May want to add a line to remove those annoying lock files (.#filename)
emacs_tmp_files += Dir.glob( File.join(Rails.root, "*", "#") )
