How can I search for available rake tasks?
(where “gem” is the thing you are searching for)
The above example will return all of the rake tasks relating to gems:
rake gems:build # Build any native extensions for unpacked gems
rake gems:install # Installs all required gems.
rake gems:refresh_specs # Regenerate gem specifications in correct format.
rake gems:unpack # Unpacks all required gems into vendor/gems.
rake gems:unpack:dependencies # Unpacks all required gems and their dependencies into vendor/gems.
rake rails:freeze:gems # Lock this application to the current gems (by unpacking them into vendor/rails)
rake rails:unfreeze # Unlock this application from freeze of gems or edge and return to a fluid use of system gems
