NAME

     sftp -- Secure file transfer program

SYNOPSIS

     sftp [-vC1] [-b batchfile] [-o ssh_option] [-s subsystem | sftp_server] [-B buffer_size] [-F ssh_config] [-P sftp_server path]
	  [-R num_requests] [-S program] host
     sftp [[user@]host[:file [file]]]
     sftp [[user@]host[:dir[/]]]

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 last usage format allows the sftp client to start in a remote directory.

     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 authentication.  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 options 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 server on the remote host.  A path is useful for using sftp over protocol ver-
	     sion 1, or when the remote sshd does not have an sftp subsystem configured.

     -v      Raise logging level. This option is also passed to ssh.

     -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.

     -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 connection.  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 pathnames 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 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 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 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 specified, then dis-
	     play additional details including permissions and ownership information.

     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 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.

     rmdir path
	     Remove remote directory specified by path.

     rm path
	     Delete remote file specified by path.

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

     ! command
	     Execute command in local shell.

     !	     Escape to local shell.

     ?	     Synonym for help.
