SFTP, which stands for SSH File Transfer Protocol, or Secure File Transfer Protocol, is a separate protocol packaged with SSH that works in a similar way over a secure connection. The advantage is the ability to leverage a secure connection to transfer files and traverse the filesystem on both the local and remote system.

Transferring Files with SFTP

下载远程文件到本地

语法：

get remoteFile.txt

重命名下载的文件:

get remoteFile.txt localFile.txt

下载文件夹到本地：

get -r someDirectory

下载文件夹到本地且保持文件夹权限属性：

get -Pr someDirectory

上载本地文件到远程

语法：

put localFile.txt

其他语法和下载 get 基本相同。

查看远程服务器可用容量：

df -h

以上命令无法直接查看本地容量，可用 ! 来实现：

!
df -h

使用 ! 后任何本地命令都可以使用了，要想切换回 sftp 模式，使用如下命令：

exit

以上就是常用的 SFTP 用法。

常用客户端

FileZilla (corss platform)
WinSCP (windows)
