递归打印文件路径

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 . . ./etc ./etc/update.cfg ./etc/version ./etc/keys ./etc/keys/node.localhost.id_rsa ./etc/keys/node.localhost.id_rsa.pub ./etc/node-redhat.cfg.sample ./etc/node-fedora.cfg.sample ./scripts ./scripts/selinux ./scripts/selinux/nx-unconfined-fedora24.pp ./scripts/selinux/fedora25 ./scripts/selinux/fedora25/nx-unconfined.pp ./scripts/selinux/nx.pp ./scripts/selinux/nx-unconfined.pp ./scripts/selinux/nx-system.pp ./scripts/setup ./scripts/setup/nxrunner ./scripts/setup/install ./scripts/restricted/nxcopy.sh ./scripts/restricted/nxquotaadd.sh ./scripts/restricted/nxpasswd.sh ./scripts/etc ./scripts/etc/localhost ./scripts/etc/localhost/runner.cfg ./scripts/etc/pam.d/nx ./scripts/etc/pam.d/nx-login ./scripts/etc/pam.d/nx-legacy ./scripts/etc/nxnode ./scripts/etc/nxserver ./scripts/env/nxcustomerrormessages.sh ./scripts/env/nxpreload.sh ./scripts/env/forcelogout.sh ./scripts/env/nxvdvariables.sh
