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 necessary 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 following commands fail: get, put,
	      rename, ln, rm, mkdir, chdir, ls, lchdir, chmod,	chown,	chgrp,
	      lpwd, df, symlink, and lmkdir.  Termination on error can be sup‐
	      pressed 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  pub‐
	      lic  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 download‐
	      ing.   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 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 con‐
       tain spaces must be enclosed in quotes.	Any  special  characters  con‐
       tained  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 specified).	 If the -h flag is  specified,
	      the  capacity  information  will be displayed using "human-read‐
	      able" suffixes.  The -i flag requests display of inode  informa‐
	      tion  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 permis‐
	      sions 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 direc‐
	      tory if path is not specified.  ls-options may contain any flags
	      supported by the local system's ls(1) command.  path may contain
	      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 speci‐
	      fied 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(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 lexicograph‐
	      ical.

       -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 pow‐
	      ers 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 [-Ppr] 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)	 char‐
	      acters 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 permis‐
	      sions 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.

       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.

       ! Ns command
	      Execute command in local shell.

       !      Escape to local shell.

       ?      Synonym for help.
