sftp -- Secure file transfer program
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 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
The last usage format allows the sftp client to start in a remote directory.
The options are as follows:
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, 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* ).
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
version 1, or when the remote sshd does not have an sftp subsystem
-v Raise logging level. This option is also passed to ssh.
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).
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.
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.
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.
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.
Change remote directory to 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.
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
display additional details including permissions and ownership
Set local umask to umask.
Create remote directory specified by path.
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.
pwd Display remote working directory.
quit Quit sftp.
rename oldpath newpath
Rename remote file from oldpath to newpath.
Remove remote directory specified by path.
Delete remote file specified by path.
symlink oldpath newpath
Create a symbolic link from oldpath to newpath.
Display the sftp protocol version.
Execute command in local shell.
! Escape to local shell.
