你也想要生成这个目录树层结构吗?,按下面操作即可:

.
├── etc
│   └── greet-api.yaml
├── go.mod
├── go.sum
├── greet.api
├── greet.go
└── internal
    ├── config
    │   └── config.go
    ├── handler
    │   ├── greethandler.go
    │   └── routes.go
    ├── logic
    │   └── greetlogic.go
    ├── svc
    │   └── servicecontext.go
    └── types
        └── types.go

7 directories, 11 files

1 、安装 tree

#  mac 下使用 brew包管理工具
brew install tree
# linux 下使用yum安装
yum install tree

2、 安装成功后,直接在终端使用,使用 --help 查看帮助信息

tree --help

看到如下功能

usage: tree [-acdfghilnpqrstuvxACDFJQNSUX] [-H baseHREF] [-T title ]
    [-L level [-R]] [-P pattern] [-I pattern] [-o filename] [--version]
    [--help] [--inodes] [--device] [--noreport] [--nolinks] [--dirsfirst]

  -s            Print the size in bytes of each file.
  -h            Print the size in a more human readable way.
  --si          Like -h, but use in SI units (powers of 1000).

  -U            Leave files unsorted.
  -r            Reverse the order of the sort.
  --dirsfirst   List directories before files (-U disables).
  --sort X      Select sort: name,version,size,mtime,ctime.
  ------- Graphics options ------

3、 输出你的树层目录结构

  • cd 目标文件夹路径
  • 然后 tree 一下,会将该层级下所有文件都遍历了输出,不管层级多深

4、 常用技巧

我们可以在目录遍历时使用 -L 参数指定遍历层级

tree -L 2

如果你想把一个目录的结构树导出到文件 Readme.md ,可以这样操作

tree -L 2 >README.md //然后我们看下当前目录下的 README.md 文件

只显示文件夹

tree -d 

显示项目的层级,n表示层级数。例:显示项目三层结构,tree -l 3;

tree -L n 

tree -I pattern 用于过滤不想要显示的文件或者文件夹。比如要过滤项目中的node_modules文件夹;

tree -I “node_modules”
