Have you ever wondered where a particular rake task is defined? Enter
rake -W (introduced in
$ rake -W db:schema:load
rake db:schema:load /Users/bozhidar/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/activerecord-4.1.1/lib/active_record/railties/databases.rake:236:in `block (2 levels) in <top (required)>'
rake db:schema:load_if_ruby /Users/bozhidar/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/activerecord-4.1.1/lib/active_record/railties/databases.rake:240:in `block (2 levels) in <top (required)>'
You can also invoke
rake -W without an argument and you’ll get a listing of all available rake tasks and their source locations.
Pretty neat, right?
