NAME
     sftp - secure file transfer program

SYNOPSIS
     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] host
     sftp [[user@]host[:file [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 compres
     sion.  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-inter
     active authentication method is used; otherwise it will do so after suc
     cessful 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 necessary to configure non-interactive authentica
     tion to obviate the need to enter a password at connection time (see
     sshd(8) and ssh-keygen(1) for details).  The options are as follows:

     -1      Specify the use of protocol version 1.

     -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 following commands fail: get, put,
	     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*).

     -C      Enables compression (via sshs -C flag).

     -F ssh_config
	     Specifies an alternative per-user configuration file for ssh(1).
	     This option is directly passed to ssh(1).

     -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 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.

     -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 16 outstanding requests.

     -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 for using sftp over protocol
	     version 1, or when the remote sshd(8) does not have an sftp sub
	     system 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) char
	     acters 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) char
	     acters and may match multiple files.  own must be a numeric UID.

     exit    Quit sftp.

     get [-P] 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 direc
	     tory.  If the -P flag is specified, then full file permissions
	     and access times are copied too.

     help    Display help text.

     lcd path
	     Change local directory to path.

     lls [ls-options [path]]
	     Display local directory listing of either path or current direc
	     tory if path is not specified.  ls-options may contain any flags
	     supported by the local systems ls(1) command.  path may contain
	     glob(3) characters and may match multiple files.

     lmkdir path
	     Create local directory specified by path.

     ln oldpath newpath
	     Create a symbolic link from oldpath to newpath.

     lpwd    Print local working directory.

     ls [-1aflnrSt] [path]
	     Display a remote directory listing of either path or the current
	     directory if path is not specified.  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 lexi
		     cographical.

	     -l      Display additional details including permissions and own
		     ership 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 [-P] 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(3) charac
	     ters and may match multiple files.  If it does and remote-path is
	     specified, then remote-path must specify a directory.  If the -P
	     flag is specified, then the files full permission and access
	     time are copied too.

     pwd     Display remote working directory.

     quit    Quit sftp.

     rename oldpath newpath
	     Rename remote file from oldpath to newpath.

     rm path
	     Delete remote file specified by path.

     rmdir path
	     Remove remote directory specified by path.

     symlink oldpath newpath
	     Create a symbolic link from oldpath to newpath.

     version
	     Display the sftp protocol version.

     ! command
	     Execute command in local shell.

     !	     Escape to local shell.

     ?	     Synonym for help.
