+NAME
+ sftp M-bM-^@M-^S OpenSSH secure file transfer
+
+SYNOPSIS
+ sftp [-46AaCfNpqrv] [-B buffer_size] [-b batchfile] [-c cipher]
+ [-D sftp_server_command] [-F ssh_config] [-i identity_file]
+ [-J destination] [-l limit] [-o ssh_option] [-P port]
+ [-R num_requests] [-S program] [-s subsystem | sftp_server]
+ [-X sftp_option] destination
+
+DESCRIPTION
+ sftp is a file transfer program, similar to ftp(1), which performs all
+ operations over an encrypted ssh(1) transport. It may also use many
+ features of ssh, such as public key authentication and compression.
+
+ The destination may be specified either as [user@]host[:path] or as a URI
+ in the form sftp://[user@]host[:port][/path].
+
+ If the destination includes a path and it is not a directory, sftp will
+ retrieve files automatically if a non-interactive authentication method
+ is used; otherwise it will do so after successful interactive
+ authentication.
+
+ If no path is specified, or if the path is a directory, sftp will log in
+ to the specified host and enter interactive command mode, changing to the
+ remote directory if one was specified. An optional trailing slash can be
+ used to force the path to be interpreted as a directory.
+
+ Since the destination formats use colon characters to delimit host names
+ from path names or port numbers, IPv6 addresses must be enclosed in
+ square brackets to avoid ambiguity.
+
+ The options are as follows:
+
+ -4 Forces sftp to use IPv4 addresses only.
+
+ -6 Forces sftp to use IPv6 addresses only.
+
+ -A Allows forwarding of ssh-agent(1) to the remote system. The
+ default is not to forward an authentication agent.
+
+ -a Attempt to continue interrupted transfers rather than overwriting
+ existing partial or complete copies of files. If the partial
+ contents differ from those being transferred, then the resultant
+ file is likely to be corrupt.
+
+ -B buffer_size
+ Specify 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.
+
+ -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(8) and ssh-keygen(1) for details).
+
+ A batchfile of M-bM-^@M-^X-M-bM-^@M-^Y 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, and lmkdir.
+
+ Termination on error can be suppressed on a command by command
+ basis by prefixing the command with a M-bM-^@M-^X-M-bM-^@M-^Y character (for example,
+ -rm /tmp/blah*). Echo of the command may be suppressed by
+ prefixing the command with a M-bM-^@M-^X@M-bM-^@M-^Y character. These two prefixes
+ may be combined in any order, for example -@ls /bsd.
+
+ -C Enables compression (via ssh's -C flag).
+
+ -c cipher
+ Selects the cipher to use for encrypting the data transfers.
+ This option is directly passed to ssh(1).
+
+ -D sftp_server_command
+ Connect directly to a local sftp server (rather than via ssh(1)).
+ 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(1).
+ This option is directly passed to ssh(1).
+
+ -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.
+
+ -i identity_file
+ Selects the file from which the identity (private key) for public
+ key authentication is read. This option is directly passed to
+ ssh(1).
+
+ -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(1).
+
+ -l limit
+ Limits the used bandwidth, specified in Kbit/s.
+
+ -N Disables quiet mode, e.g. to override the implicit quiet mode set
+ by the -b flag.
+
+ -o ssh_option
+ Can be used to pass options to ssh in the format used in
+ ssh_config(5). This is useful for specifying options for which
+ there is no separate sftp command-line flag. For example, to
+ specify an alternate port use: sftp -oPort=24. For full details
+ of the options listed below, and their possible values, see
+ ssh_config(5).

+
+ -P port
+ Specifies the port to connect to on the remote host.
+
+ -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(1).
+
+ -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.
+
+ -r Recursively copy entire directories when uploading and
+ downloading. Note that sftp does not follow symbolic links
+ encountered in the tree traversal.
+
+ -S program
+ Name of the program to use for the encrypted connection. The
+ program must understand ssh(1) options.
+
+ -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(8) does
+ not have an sftp subsystem configured.
+
+ -v Raise logging level. This option is also passed to ssh.
+
+ -X sftp_option
+ Specify an option that controls aspects of SFTP protocol
+ behaviour. The valid options are:
+
+ nrequests=value
+ Controls how many concurrent SFTP read or write requests
+ may be in progress at any point in time during a download
+ or upload. By default 64 requests may be active
+ concurrently.
+
+ buffer=value
+ Controls the maximum buffer size for a single SFTP
+ read/write operation used during download or upload. By
+ default a 32KB buffer is used.
+
+INTERACTIVE COMMANDS
+ Once in interactive mode, sftp understands a set of commands similar to
+ those of ftp(1). Commands are case insensitive. Pathnames that contain
+ spaces must be enclosed in quotes. Any special characters contained
+ within pathnames that are recognized by glob(3) must be escaped with
+ backslashes (M-bM-^@M-^X\M-bM-^@M-^Y).
+
+ bye Quit sftp.
+
+ cd [path]
+ Change remote directory to path. If path is not specified, then
+ change directory to the one the session started in.
+
+ chgrp [-h] grp path
+ Change group of file path to grp. path may contain glob(7)
+ characters and may match multiple files. grp must be a numeric
+ GID.
+
+ If the -h flag is specified, then symlinks will not be followed.
+ Note that this is only supported by servers that implement the
+ "lsetstat@openssh.com" extension.
+
+ chmod [-h] mode path
+ Change permissions of file path to mode. path may contain
+ glob(7) characters and may match multiple files.
+
+ If the -h flag is specified, then symlinks will not be followed.
+ Note that this is only supported by servers that implement the
+ "lsetstat@openssh.com" extension.
+
+ chown [-h] own path
+ Change owner of file path to own. path may contain glob(7)
+ characters and may match multiple files. own must be a numeric
+ UID.
+
+ If the -h flag is specified, then symlinks will not be followed.
+ Note that this is only supported by servers that implement the
+ "lsetstat@openssh.com" extension.
+
+ copy oldpath newpath
+ Copy remote file from oldpath to newpath.
+
+ Note that this is only supported by servers that implement the
+ "copy-data" extension.
+
+ cp oldpath newpath
+ Alias to copy command.
+
+ df [-hi] [path]
+ Display usage information for the filesystem holding the current
+ directory (or path if specified). If the -h flag is specified,
+ the capacity information will be displayed using "human-readable"
+ suffixes. The -i flag requests display of inode information in
+ addition to capacity information. This command is only supported
+ on servers that implement the M-bM-^@M-^\statvfs@openssh.comM-bM-^@M-^] extension.
+
+ exit Quit sftp.
+
+ get [-afpR] remote-path [local-path]
+ Retrieve the remote-path and store it on the local machine. If
+ the local path name is not specified, it is given the same name
+ it has on the remote machine. remote-path may contain glob(7)
+ characters and may match multiple files. If it does and
+ local-path is specified, then local-path must specify a
+ directory.
+
+ If the -a flag is specified, then attempt to resume partial
+ transfers of existing files. Note that resumption assumes that
+ any partial copy of the local file matches the remote copy. If
+ the remote file contents differ from the partial local copy then
+ the resultant file is likely to be corrupt.
+
+ If the -f flag is specified, then fsync(2) will be called after
+ the file transfer has completed to flush the file to disk.
+
+ If the -p flag is specified, then full file permissions and
+ access times are copied too.
+
+ If the -R flag is specified then directories will be copied
+ recursively. Note that sftp does not follow symbolic links when
+ performing recursive transfers.
+
+ help Display help text.
+
+ lcd [path]
+ Change local directory to path. If path is not specified, then
+ change directory to the local user's home directory.
+
+ lls [ls-options [path]]
+ Display local directory listing of either path or current
+ directory if path is not specified. ls-options may contain any
+ flags supported by the local system's ls(1) command. path may
+ contain glob(7) characters and may match multiple files.
+
+ lmkdir path
+ Create local directory specified by path.
+
+ ln [-s] oldpath newpath
+ Create a link from oldpath to newpath. If the -s flag is
+ specified the created link is a symbolic link, otherwise it is a
+ hard link.
+
+ lpwd Print local working directory.
+
+ ls [-1afhlnrSt] [path]
+ Display a remote directory listing of either path or the current
+ directory if path is not specified. path may contain glob(7)
+ characters and may match multiple files.
+
+ The following flags are recognized and alter the behaviour of ls
+ accordingly:
+
+ -1 Produce single columnar output.
+
+ -a List files beginning with a dot (M-bM-^@M-^X.M-bM-^@M-^Y).
+
+ -f Do not sort the listing. The default sort order is
+ lexicographical.
+
+ -h When used with a long format option, use unit suffixes:
+ Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Petabyte,
+ and Exabyte in order to reduce the number of digits to
+ four or fewer using powers of 2 for sizes (K=1024,
+ M=1048576, etc.).
+
+ -l Display additional details including permissions and
+ ownership information.
+
+ -n Produce a long listing with user and group information
+ presented numerically.
+
+ -r Reverse the sort order of the listing.
+
+ -S Sort the listing by file size.
+
+ -t Sort the listing by last modification time.
+
+ lumask umask
+ Set local umask to umask.
+
+ mkdir path
+ Create remote directory specified by path.
+
+ progress
+ Toggle display of progress meter.
+
+ put [-afpR] local-path [remote-path]
+ Upload local-path and store it on the remote machine. If the
+ remote path name is not specified, it is given the same name it
+ has on the local machine. local-path may contain glob(7)
+ characters and may match multiple files. If it does and
+ remote-path is specified, then remote-path must specify a
+ directory.
+
+ If the -a flag is specified, then attempt to resume partial
+ transfers of existing files. Note that resumption assumes that
+ any partial copy of the remote file matches the local copy. If
+ the local file contents differ from the remote local copy then
+ the resultant file is likely to be corrupt.
+
+ If the -f flag is specified, then a request will be sent to the
+ server to call fsync(2) after the file has been transferred.
+ Note that this is only supported by servers that implement the
+ "fsync@openssh.com" extension.
+
+ If the -p flag is specified, then full file permissions and
+ access times are copied too.
+
+ If the -R flag is specified then directories will be copied
+ recursively. Note that sftp does not follow symbolic links when
+ performing recursive transfers.
+
+ pwd Display remote working directory.
+
+ quit Quit sftp.
+
+ reget [-fpR] remote-path [local-path]
+ Resume download of remote-path. Equivalent to get with the -a
+ flag set.
