linux命令之查看目录树结构-tree

时间:2022-07-08 12:55:59

linux下我们经常要查看目录的组织结构,tree命令以树形结构显示文件目录。

直接使用tree dir显示目录下所有文件和文件夹:

$ tree go
go
├── build.sh
├── compile-run.sh
├── main
└── main.go

tree -d选项只查看目录下文件夹:

$ tree -d cmake
cmake
├── cmake_exe
│   └── CMakeFiles
│       ├── 3.5.1
│       │   ├── CompilerIdC
│       │   └── CompilerIdCXX
│       ├── CMakeTmp
│       └── main.dir
├── cmake_lib
│   ├── bin
│   ├── CMakeFiles
│   │   ├── 3.5.1
│   │   │   ├── CompilerIdC
│   │   │   └── CompilerIdCXX
│   │   └── CMakeTmp
│   ├── lib
│   │   └── CMakeFiles
│   │       └── libhello.dir
│   └── src
│       └── CMakeFiles
│           └── hello.dir
└── cmake_so

tree -L leve查看目录树深度:

$ tree -d -L 2 shell
shell
├── autoupdate
│   └── tools
└── expect-dir
    ├── bin
    ├── expect5.45
    ├── expect-tool
    └── tcl8.4.11

7 directories


在shell终端输入tree --help查看所有选项:

$ tree --help
