+# Run A Rake Task Programmatically
+
+Typically the way to run a rake task is with the `rake` command from the
+command line.
+
+```bash
+$ rake example:env
+```
+
+What if you have a rake task that you want to invoke as part of a Ruby script
+or from somewhere in your Rails codebase?
+
+Your tasks can be called programmatically as well.
+
+Consider these two rake tasks:
+
+```ruby
+namespace :example do
+  task :env do
+    puts "Current Environment: #{Rails.env.upcase}"
+  end
+
+  task :message, [:msg] do |task, args|
+    puts "Message: #{args[:msg]}"
+  end
+end
+```
+
+These can be called from somewhere else by referencing and invoking them like
+so.
+
+```ruby
+Rake::Task["example:env"].invoke
+Rake::Task["example:message"].invoke("Nice rake task!")
+```
