Options	Description
-4	- sftp가 IPv4 주소 체계를 사용하도록 강제한다.
-6	- sftp가 IPv6 주소 체계를 사용하도록 강제한다.
-A	- ssh-agent의 원격지 시스템으로의 포워딩을 허용한다. - 기본값은 No 이다.
-a	- 기존 파일의 일부 또는 전체 복사본을 덮어쓰지 않고 중단된 전송을 계속 시도한다. - 일부 내용이 전송되는 내용과 다른 경우, 결과 파일이 손상되었을 가능성이 높다.
-C	- ssh 명령의 -C Flag를 통한 파일 압축을 허용한다.
-f	- Requests that files be flushed to disk immediately after transfer - When uploading files, this feature is only enabled if the server implements the "fsync@openssh.com" extension
-N	- Quiet Mode를 해제한다. - e.g. to override the implicit quiet mode set by the -b flag
-p	- Preserves modification times, access times, and modes from the original files transferred
-q	- Quiet mode - disables the progress meter as well as warning and diagnostic messages from ssh
-r	- Recursively copy entire directories when uploading and downloading - Note that sftp does not follow symbolic links encountered in the tree traversal
-v	- Logging Level을 상향 조정한다.
-B <buffer_size>	- 파일을 전송할 때 사용되는 버퍼의 크기를 지정한다. - 기본값은 32,768 bytes이다.
-b <batchfile>	- Batch mode reads a series of commands from an input batchfile instead of stdin - Since it lacks user interaction, it should be used in conjunction with non-interactive authentication to obviate the need to enter a password at connection time (see sshd and ssh-keygen for details) - A batchfile of ‘-’ may be used to indicate standard input - sftp will abort if any of the following commands fail: get, put, reget, reput, rename, ln, rm, mkdir, chdir, ls, lchdir, copy, cp, chmod, chown, chgrp, lpwd, df, symlink, lmkdir - Termination on error can be suppressed on a command by command basis by prefixing the command with a ‘-’ character (for example, -rm /tmp/blah*) - Echo of the command may be suppressed by prefixing the command with a ‘@’ character - These two prefixes may be combined in any order, for example -@ls /bsd.
-c <cipher>	- 암호화 전송 시 사용할 암호화 알고리즘을 명시한다.
-D <sftp_server_command>	- Connect directly to a local sftp server (rather than via ssh) - A command and arguments may be specified, for example "/path/sftp-server -el debug3" - This option may be useful in debugging the client and server
-F <ssh_config>	- Specifies an alternative per-user configuration file for ssh - 이 옵션값은 ssh 명령에 곧바로 인계된다.
-i <identify_file>	- 공개키 인증을 위한 Private Key를 명시한다. - 이 옵션값은 ssh 명령에 곧바로 인계된다.
-J <destination>	- Connect to the target host by first making an sftp connection to the jump host described by destination and then establishing a TCP forwarding to the ultimate destination from there. - Multiple jump hops may be specified separated by comma characters - This is a shortcut to specify a ProxyJump configuration directive - This option is directly passed to ssh
-l <limit>	- 대역폭을 <limit> Kbit/s 로 제한한다.
-o <ssh_option>	* 하단에 상세히 서술함.
-P <port>	- 연결하고자 하는 원격지 호스트의 포트번호를 명시한다.
-R <num_requests>	- Specify how many requests may be outstanding at any one time - Increasing this may slightly improve file transfer speed but will increase memory usage - The default is 64 outstanding requests.
-S <program>	- Encrypted Connection 상에서 실행할 프로그램 이름을 명시한다.
-s <subsystem \| sftp_server>	- Specifies the SSH2 subsystem or the path for an sftp server on the remote host - A path is useful when the remote sshd does not have an sftp subsystem configured
-X <sftp_option>	- SFTP protocol behaviour를 명시한다. nrequests=value - Concurrent SFTP가 동시에 읽고 쓸 수 있는 요청 개수를 지정한다. - 기본값은 64이다. buffer=value - Single SFTP의 최대 버퍼 크기를 KB 단위로 지정한다. - 기본값은 32KB이다.
<destination>	- destination은 아래 형태로 명시되어야 한다: - [user@]host[:path] - sftp://[user@]host[:port][/path]
