- secure file transfer program
sftp [-1Cv] [-B buffer_size] [-b batchfile] [-F ssh_config]
[-o ssh_option] [-P sftp_server_path] [-R num_requests]
[-S program] [-s subsystem | sftp_server] hostsftp [[user@]host[:file [file]]]
sftp [[user@]host[:dir[/]]]
sftp -b batchfile [user@]host
The sftp utility is an interactive file transfer program with a user interface similar to ftp(1) that uses the ssh(1) command to create a secure connection to the server.
sftp implements the SSH File Transfer Protocol as defined in IETF draft-ietf-secsh-filexfer. There is no relationship between the protocol used by sftp and the FTP protocol (RFC 959) provided by ftp(1).
The first usage format causes sftp to connect to the specified host and enter an interactive mode. If a username was provided then sftp tries to log in as the specified user. If a directory is provided then sftp tries to change the current directory on the server to the specified directory before entering the interactive mode.
The second usage format retrieves the specified file from the server and copies it to the specified target file or directory on the client. If a username is specified sftp tries to log in as the specified user.
The following options are supported:
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. A batchfile of - can be used to indicate standard input. sftp aborts if any of the following commands fail: get, put, rm, rename, ln, rm, mkdir, chdir, ls, lchdir, chmod, chown, chgrp, lpwd, and 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*).
Specifies the size of the buffer that sftp uses when transferring files. Larger buffers require fewer round trips at the cost of higher memory consumption. The default is 32768 bytes.
Enables compression, using the -C flag in ssh(1).
Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1).
Specifies an option to be directly passed to ssh(1).
Executes the specified path as an sftp-server and uses a pipe, rather than an ssh connection, to communicate with it. This option can be useful in debugging the sftp client and server. When the -P is specified, the -S option is ignored.
Specifies how many requests can be outstanding at any one time. Increasing this can slightly improve file transfer speed but increases memory usage. The default is 64 outstanding requests.
Specifies the SSH2 subsystem or the path for an sftp server on the remote host. A path is useful for using sftp over protocol version 1, or when the remote sshd does not have an sftp subsystem configured.
Uses the specified program instead of ssh(1) to connect to the sftp server. When the -P option is specified, the -S option is ignored. The program must understand ssh(1) options.
Raises logging level. This option is also passed to ssh(1).
Specifies the use of protocol version 1.
The following operands are supported:
The name of the host to which sftp connects and logs into.
Once in interactive mode, sftp understands a set of commands similar to those of ftp(1). Commands are case insensitive and path names can be enclosed in quotes if they contain spaces.
Quits sftp.
Changes remote directory to path.
Changes group of file path to grp. grp must be a numeric GID.
Changes permissions of file path to mode.
Changes owner of file path to own. own must be a numeric UID.
Quits sftp.
Retrieves the remote-path and stores it on the local machine. If the local path name is not specified, it is specified the same name it has on the remote machine. If the -P flag is specified, then the file's full permission and access time are copied too.
Displays help text.
Identical to the ? command.
Changes local directory to path.
Displays local directory listing of either path or current directory if path is not specified.
Creates local directory specified by path.
Creates a link from oldpath to newpath.
Prints local working directory.
Displays remote directory listing of either path or current directory if path is not specified. path can contain wildcards.
The ls supports the following options:
Lists files beginning with a dot (.).
Does not sort the listing. The default sort order is lexicographical.
Displays additional details including permissions and ownership information.
Produces a long listing with user and group information presented numerically.
Reverses the sort order of the listing.
Sorts the listing by file size.
Sorts the listing by last modification time.
Produces single column output.
Sets local umask to umask.
Creates remote directory specified by path.
Uploads local-path and stores it on the remote machine. If the remote path name is not specified, it is specified the same name it has on the local machine. If the -P flag is specified, then the file's full permission and access time are copied too.
Displays remote working directory.
Quits sftp.
Renames remote file from oldpath to newpath.
Deletes remote file specified by path.
Removes remote directory specified by path.
Creates a symbolic link from oldpath to newpath.
Displays the sftp protocol version.
Include a comment. This is useful in batch files.
If command is not specified, escapes to the local shell.
If command is specified, executes command in the local shell.
Displays help text.
Identical to the help command.
The following exit values are returned:
Successful completion.
An error occurred.
