SSH SFTP 应用
==================================================

sftp 就是用 ssh 隧道承载 ftp 数据，因此操作方式与 ftp 基本一致。


登录主机
--------------------------------------------------

使用交互方式登录远程主机:

.. code-block:: bash

    sftp dummy@10.0.0.1

如果配置文件保存了相关信息则可以简化:

.. code-block:: bash

    Host dummy
        HostName 10.0.0.1
        User dummy
        Port 3333
        IdentityFile ~/.ssh/dummy

.. code-block:: bash

    sftp dummy

传输命令
--------------------------------------------------

在输入 *help* 命令后，会有详细的帮助信息:

.. code-block:: none

    sftp> help
    Available commands:
    bye                                Quit sftp
