sftp

sftp(1) 							   User Commands							   sftp(1)

NAME

       sftp - secure file transfer program

SYNOPSIS

       sftp [options] [user@]host[:dir[/]]

       sftp [options] [user@]host[:file1 [file1 [file | dir2]]

DESCRIPTION

       The  sftp  utility is an interactive file transfer program with a user interface similar to ftp(1) that uses the ssh(1) command to create a
       secure connection to the server.

       sftp implements the SSH File Transfer Protocol as defined in IETF draft-ietf-secsh-filexfer. There is no relationship between the  protocol
       used by sftp and the FTP protocol (RFC959) provided by ftp(1).

       The  first  usage format causes sftp to connect to the given host and enter an interactive mode. If a username was provided then sftp tries
       to log in as the given user. If a directory is provided then sftp tries to change the current directory on the server to the  given  direc-
       tory before entering the interactive mode.

       The  second  usage  format retrieves the given file from the server and copies it to the given target file or directory on the client. If a
       username is given sftp tries to log in as the given user.

OPTIONS

       The following options are supported:

       -1

	   Specifies the use of protocol version 1.

       -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 aborts if any of the following commands fail: get, rm, and lmkdir.

       -B buffer_size

	   Specifies 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, using the -C flag in ssh(1).

       -F ssh_config

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

       -o ssh_option

	   Specifies an option to be directly passed to ssh(1).

       -P sftp_server path

	   Executes the given path as an sftp-server and uses a pipe, rather than an ssh connection, to communicate with it. This  option  can	be
	   useful in debugging the sftp client and server. The -P and -S options are mutually exclusive.

       -R num_requests

	   Specifies  how many requests can be outstanding at any one time. Increasing this can slightly improve file transfer speed but increases
	   memory usage. The default is 16 outstanding requests.

       -S ssh program path

	   Uses the given program instead of ssh(1) to connect to the sftp server. The -P and -S options are mutually exclusive.

       -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 does not have an sftp subsystem configured.

       -v

	   Raises logging level. This option is also passed to ssh(1).

OPERANDS

       The following operands are supported:

       hostname | user@hostname

	   The name of the host to which sftp connects and logs into.

INTERACTIVE COMMANDS

       Once in interactive mode, sftp understands a set of commands similar to those of ftp(1). Commands are case insensitive and pathnames can be
       enclosed in quotes if they contain spaces.

       bye

	   Quits sftp.

       cd path

	   Changes remote directory to path.

       lcd path

	   Changes local directory to path.

       chgrp grp path

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

       chmod mode path

	   Changes permissions of file path to mode.

       chown own path

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

       help

	   Displays help text.

       get [flags] remote-path [local-path]

	   Retrieves the remote-path and stores 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.

       lls [ls-options [path]]

	   Displays local directory listing of either path or current directory if path is not specified.

       lmkdir path

	   Creates local directory specified by path.

       ln oldpath newpath

	   Creates a link from oldpath to newpath.

       lpwd

	   Prints local working directory.

       ls [flags] [path]

	   Displays remote directory listing of either path or current directory if path is not specified.

       lumask umask

	   Sets local umask to umask.

       mkdir path

	   Creates remote directory specified by path.

       put [flags] local-path [local-path]

	   Uploads  local-path	and stores 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

	   Displays remote working directory.

       exit

	   Quits sftp.

       quit

	   Quits sftp.

       rename oldpath newpath

	   Renames remote file from oldpath to newpath.

       rmdir path

	   Removes remote directory specified by path.

       rm path

	   Deletes remote file specified by path.

       symlink oldpath newpath

	   Creates a symbolic link from oldpath to newpath.

       ! command

	   Executes command in local shell.

       !

	   Escapes to local shell.

       ?

	   Synonym for help.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       1	An error occurred.
