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 .
