Rake TasksUnderstanding rake tasks and how to write one
In your RAILS project working directory, when you type rake routes it lists all the routes you made in your application. This rake routes is a 'rake' task which is specified to list all routes in an application. Also there is a task rake db:migrate that runs your migrations. There are many tasks available to you, and they all can be listed using rake -T. But you are not restricted to the tasks listed in rake -T only. You can write your own custom rake tasks also. They will do mundane as well as hefty tasks you will ask them to do for you. But then, how to?
Rake is ruby make. It replaces Unix make and use Rakefile and .rake files to build up a list of tasks.

If you are working with RAILS, your tasks are stored in /lib/tasks folder.
