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 compresM--
     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-interM--
     active authentication method is used; otherwise it  will  do
so after sucM--
     cessful interactive authentication.

     The  last  usage format allows the sftp client to start in a
remote direcM--
     tory.

     The options are as follows:

     -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 authentica-
tion.  sftp
             will  abort  if  any of the following commands fail:
get, put,
             rename, ln, rm, mkdir, chdir, lchdir and lmkdir.

     -o ssh_option
             Can be used to pass options to  ssh  in  the  format
used in
             ssh_config(5).   This  is  useful for specifying op-
tions for which
             there is no separate sftp  command-line  flag.   For
example, to
             specify an alternate port use: sftp -oPort=24.

     -s subsystem | sftp_server
             Specifies the SSH2 subsystem or the path for an sftp

the cost of
             higher  memory  consumption.  The  default  is 32768
bytes.

     -C      Enables compression (via ssh's -C flag).

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

     -P sftp_server path
             Connect directly to a local sftp-server (rather than
via ssh)
             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 connec-
tion.  The
             program must understand ssh(1) options.

     -1      Specify the use of protocol version 1.

INTERACTIVE COMMANDS
     Once in interactive mode, sftp understands a set of commands
similar to
     those of ftp(1).  Commands are case  insensitive  and  path-
names may be
     enclosed in quotes if they contain spaces.

     bye     Quit sftp.

     cd path
             Change remote directory to path.

     lcd path
             Change local directory to path.

     chgrp grp path
             Change group of file path to grp.  grp must be a nu-
meric GID.

     chmod mode path

specified, then
             the file's  full  permission  and  access  time  are
copied too.

     help    Display help text.

     lls [ls-options [path]]
             Display  local  directory  listing of either path or
current direcM--
             tory 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 [path]
             Display remote directory listing of either  path  or
current direcM--
             tory if path is not specified.

     lumask umask
             Set local umask to umask.

     mkdir path
             Create remote directory specified by path.

     put [flags] local-path [local-path]
             Upload  local-path  and  store  it on the remote ma-
chine. 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 speci-
fied, 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.

     rmdir path
             Remove remote directory specified by path.

     rm path
             Delete remote file specified by path.
