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 the sftp client to start in a remote direc-
     tory.

     The final usage format allows for automated sessions using the -b option.
     In such cases, it is usually necessary to configure public key authenti-
     cation 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 ssh's -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 and pathnames may be
     enclosed in quotes if they contain spaces.

     bye	 Quit sftp.

     cd path	 Change remote directory to path.

     chgrp grp path
		 Change group of file path to grp.  grp must be a numeric GID.

     chmod mode path
		 Change permissions of file path to mode.

     chown own path
		 Change owner of file path to own.  own must be a numeric UID.

     exit	 Quit sftp.

     get [flags] 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.  If the -P flag is speci-
		 fied, then the file's full permission and access time 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
		 directory if path is not specified.

     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 [flags] [path]
		 Display remote directory listing of either path or current
		 directory if path is not specified.  If the -l flag is speci-
		 fied, then display additional details including permissions
		 and ownership information.

     lumask umask
		 Set local umask to umask.

     mkdir path  Create remote directory specified by path.

     progress	 Toggle display of progress meter.

     put [flags] 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.  If the -P flag is specified,
		 then the file's 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.
