You can run Rake tasks from your shell by running:

rake task_name

To run from from Ruby (e.g., in the Rails console or another Rake task):

Rake::Task['task_name'].invoke

To run multiple tasks in the same namespace with a single task, create the following new task in your namespace:

task :runall => [:iqmedier, :euroads, :mikkelsen, :orville] do
  # This will run after all those tasks have run
end

Ruby-on-rails – A cron job for rails: best practices

I've used the extremely popular Whenever on projects that rely heavily on scheduled tasks, and it's great. It gives you a nice DSL to define your scheduled tasks instead of having to deal with crontab format. From the README:

Whenever is a Ruby gem that provides a clear syntax for writing and deploying cron jobs.

Example from the README:

every 3.hours do
  runner "MyModel.some_process"       
  rake "my:rake:task"                 
  command "/usr/bin/my_great_command"
end

every 1.day, :at => '4:30 am' do 
  runner "MyModel.task_to_run_at_four_thirty_in_the_morning"
end

Ruby – How to run a rake task from Capistrano

A little bit more explicit, in your \config\deploy.rb, add outside any task or namespace:

namespace :rake do  
  desc "Run a task on a remote server."  
  # run like: cap staging rake:invoke task=a_certain_task  
  task :invoke do  
    run("cd #{deploy_to}/current; /usr/bin/env rake #{ENV['task']} RAILS_ENV=#{rails_env}")  
  end  
end

Then, from /rails_root/, you can run:

cap staging rake:invoke task=rebuild_table_abc
