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

     -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.

     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.

     version     Display the sftp protocol version.

     ! command   Execute command in local shell.

     !           Escape to local shell.

     ?           Synonym for help.
