14.4.3. Using the sftp Utility
				The 
sftp utility can be used to open a secure, interactive FTP session. In its design, it is similar to ftp except that it uses a secure, encrypted connection.
			
				To connect to a remote system, use a command in the following form:
			
sftp username@hostname
sftp username@hostname
				For example, to log in to a remote machine named 
penguin.example.com with john as a user name, type:
			sftp john@penguin.example.com
~]$ sftp john@penguin.example.com
john@penguin.example.com's password:
Connected to penguin.example.com.
sftp>
				After you enter the correct password, you will be presented with a prompt. The 
sftp utility accepts a set of commands similar to those used by ftp (see Table 14.3, “A selection of available sftp commands”).
			| Command | Description | 
|---|---|
| ls[directory] | List the content of a remote directory. If none is supplied, a current working directory is used by default. | 
| cddirectory | Change the remote working directory to directory. | 
| mkdirdirectory | Create a remote directory. | 
| rmdirpath | Remove a remote directory. | 
| putlocalfile [remotefile] | Transfer localfile to a remote machine. | 
| getremotefile [localfile] | Transfer remotefile from a remote machine. | 
				For a complete list of available commands, see the 
sftp(1) manual page.
