Railsアプリで実行できるrakeタスク一覧を表示する

rake -Tでrakeタスクの一覧を表示できることを知った。
capistranoはrakeタスクを追加するらしいけど、それも見れるみたい。
とりあえずテスト環境で動かしてみた。

rake db:fixtures:load          # Load fixtures into the current environment's database.  Load specific fixtures using FIXTURES=x,y
rake db:migrate                # Migrate the database through scripts in db/migrate. Target specific version with VERSION=x

rake stats                     # Report code statistics (KLOCs, etc) from the application
rake test                      # Test all units and functionals
rake test:functionals          # Run the functional tests in test/functional
rake test:integration          # Run the integration tests in test/integration
rake test:plugins              # Run the plugin tests in vendor/plugins/**/test (or specify with PLUGIN=name)

結構知らないのあるなぁ…。
rake -T freeze
とかやると、freezeに部分一致したのだけ表示してくれる。
便利。
