mac で tree コマンドを使う(ディレクトリツリーを表示する)

こんな感じのディレクトリツリーが欲しい。

./vue-test/src/
├── App.vue
├── assets
│   └── logo.png
├── components
│   └── HelloWorld.vue
├── main.js
├── router
│   └── index.js
└── views
    ├── About.vue
    └── Home.vue

そんな時に使えるのが、treeコマンドです。

インストール

homebrew のインストールが必須。

# インストール
brew install tree

# varsion 確認
tree --version
tree v1.8.0 (c) 1996 - 2018 by Steve Baker, Thomas Moore, Francesc Rocher, Florian Sesser, Kyosuke Tokoro
