[Linux][tree] treeでファイルのパーミッション/オーナー/グループを表示する

ファイルツリーのなかで、どこからどのようなパーミッションの設定になっているか確認したかったのでやり方をメモ

# 確認方法

treeコマンドの `-pug` オプションを使用すれば良いです。
`ls -lR` などでも一応再帰的に見れますが、treeコマンドのほうが見やすいです。

# 実行例

```console:treeでパーミッション/オーナー/グループの表示
$ tree -pug test/
test/
├── [-rw-rw-r-- ubuntu   ubuntu  ]  file1
├── [-rw-rw-r-- ubuntu   ubuntu  ]  file10
├── [-rw-rw-r-- ubuntu   ubuntu  ]  file2
├── [-rw-rw-r-- ubuntu   ubuntu  ]  file3
├── [-rw-rw-r-- ubuntu   ubuntu  ]  file4
├── [-rw-rw-r-- ubuntu   ubuntu  ]  file5
├── [-rw-rw-r-- ubuntu   ubuntu  ]  file6
├── [-rw-rw-r-- ubuntu   ubuntu  ]  file7
├── [-rw-rw-r-- ubuntu   ubuntu  ]  file8
├── [-rw-rw-r-- ubuntu   ubuntu  ]  file9
└── [drwxrwxr-x ubuntu   ubuntu  ]  test2
    ├── [-rw-rw-r-- ubuntu   ubuntu  ]  file20
    ├── [-rw-rw-r-- ubuntu   ubuntu  ]  file21
    ├── [-rw-rw-r-- ubuntu   ubuntu  ]  file22
    ├── [-rw-rw-r-- ubuntu   ubuntu  ]  file23
    ├── [-rw-rw-r-- ubuntu   ubuntu  ]  file24
    ├── [-rw-rw-r-- ubuntu   ubuntu  ]  file25
    ├── [-rw-rw-r-- ubuntu   ubuntu  ]  file26
    ├── [-rw-rw-r-- ubuntu   ubuntu  ]  file27
    ├── [-rw-rw-r-- ubuntu   ubuntu  ]  file28
    └── [-rw-rw-r-- ubuntu   ubuntu  ]  file29

1 directory, 20 files
```
