SFTP(1)                   BSD General Commands Manual                  SFTP(1)

NAME
     sftp -- secure file transfer program

SYNOPSIS
     sftp [-1246Cpqrv] [-B buffer_size] [-b batchfile] [-c cipher] [-D sftp_server_path] [-F ssh_config]
          [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-R num_requests] [-S program]
          [-s subsystem | sftp_server] host
     sftp [user@]host[:file ...]
     sftp [user@]host[:dir[/]]
     sftp -b batchfile [user@]host

DESCRIPTION
     sftp is an interactive 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.  sftp connects and logs into the specified host, then enters an interactive command
     mode.

     The second usage format will retrieve files automatically if a non-interactive authentication method is
     used; otherwise it will do so after successful interactive authentication.

     The third usage format allows sftp to start in a remote directory.

     The final usage format allows for automated sessions using the -b option.  In such cases, it is neces-sary necessary
     sary to configure non-interactive authentication to obviate the need to enter a password at connection
     time (see sshd(8) and ssh-keygen(1) for details).

     Since some usage formats use colon characters to delimit host names from path names, IPv6 addresses
     must be enclosed in square brackets to avoid ambiguity.

     The options are as follows:

     -1      Specify the use of protocol version 1.

     -2      Specify the use of protocol version 2.

     -4      Forces sftp to use IPv4 addresses only.

     -6      Forces sftp to use IPv6 addresses only.

     -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.  A
             batchfile of `-' may be used to indicate standard input.  sftp will abort if any of the follow-ing following
             ing commands fail: get, put, rename, ln, rm, mkdir, chdir, ls, lchdir, 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 `-' character (for example, -rm /tmp/blah*).

     -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_path
             Connect directly to a local sftp server (rather than via ssh(1)).  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).

     -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).

     -l limit
             Limits the used bandwidth, specified in Kbit/s.

     -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 use-ful useful
             ful for using sftp over protocol version 1, or when the remote sshd(8) does not have an sftp
             subsystem configured.

     -v      Raise logging level.  This option is also passed to ssh.

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 (`\').

     bye     Quit sftp.

     cd path
             Change remote directory to path.

     chgrp grp path
             Change group of file path to grp.  path may contain glob(3) characters and may match multiple
             files.  grp must be a numeric GID.

     chmod mode path
             Change permissions of file path to mode.  path may contain glob(3) characters and may match
             multiple files.

     chown own path
             Change owner of file path to own.  path may contain glob(3) characters and may match multiple
             files.  own must be a numeric UID.

     df [-hi] [path]
             Display usage information for the filesystem holding the current directory (or path if speci-fied). specified).
             fied).  If the -h flag is specified, the capacity information will be displayed using "human-readable" "humanreadable"
             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
             ``statvfs@openssh.com'' extension.

     exit    Quit sftp.

     get [-Ppr] 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(3) characters and may match multiple files.  If it does and local-path is specified, then
             local-path must specify a directory.

             If either the -P or -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.

     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 con-tain contain
             tain glob(3) 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 sym-bolic symbolic
             bolic 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 spec-ified. specified.
             ified.  path may contain glob(3) 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 (`.').

             -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, Giga-byte, Gigabyte,
                     byte, 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

             Toggle display of progress meter.

     put [-Ppr] local-path [remote-path]
             Upload local-path and store it on the remote machine.  If the remote path name is not speci-fied, specified,
             fied, it is given the same name it has on the local machine.  local-path may contain glob(3)
             characters and may match multiple files.  If it does and remote-path is specified, then
             remote-path must specify a directory.

             If either the -P or -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.
