bundle outdatedコマンド
現在のアプリディレクトリのgemに更新がないかをチェックしてくれるコマンドらしいです！(今日知ったw)
RailsやGemのバージョンアップ対応などで、地味に助かりそうな機能だなという感想でした(小並感...)
実際にコマンドを打ってみるとこんな感じ↓↓↓
~/sample_app (master|✔) $ bundle outdated Your Gemfile lists the gem spring (>= 0) more than once. You should probably keep only one of them. Remove any duplicate entries and specify the gem only once (per group). While it's not a problem now, it could cause errors if you change the version of one of them later. The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`. Fetching gem metadata from https://rubygems.org/............
