tree命令输出的是经过格式化的文件路径信息，如下所示

larry@larry-pc:~$ tree
.
├── bin
│   ├── drivers
│   ├── nxagent
│   ├── nxauth
│   ├── nxkb
│   └── nxusbd
├── etc
│   ├── core
│   ├── keys
│   │   ├── host
│   │   │   ├── nx_host_rsa_key
│   │   │   └── nx_host_rsa_key.crt
│   │   ├── node.localhost.id_dsa
│   ├── node.cfg
│   ├── node-debian.cfg.sample
│   ├── node-mandriva.cfg.sample

但有时我们希望递归得打印所有子文件的完整路径，此时可以使用find命令

larry@larry-pc:~/下载/nomachine_8.4.2_1_x86_64/NX$ sudo find .
