About sftp
Secure file transfer program.
Syntax
sftp [-1Cv] [-B buffer_size] [-b batchfile] [-F
ssh_config] [-o ssh_option] [-P sftp_server_path] [-R
num_requests] [-S program] [-s subsystem | sftp_server] host
sftp [[user@]host[:file [file]]]
sftp [[user@]host[:dir[/]]]
sftp -b batchfile [user@]host
| -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 there is no separate sftp command-line flag. For
example, to specify an alternate port use: sftp -oPort=24.
For full details of the options listed below, and their
possible values, see ssh_config(5).

| -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 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 subsystem configured. |
| -v |
Raise logging level. This option
is also passed to ssh. |
Once in interactive mode, sftp understands a set of commands
similar to those of ftp.
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. |
| 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. |
| 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 specified, 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. |
| pwd |
Display remote working
directory. |
| quit |
Quit sftp. |
| rename oldpath
newpath |
Rename remote file from oldpath
to newpath. |
| rm path |
Delete remote file specified by
path. |
| rmdir path |
Remove remote directory
specified by path. |
| symlink oldpath
newpath |
Create a symbolic link from
oldpath to newpath. |
| version |
Display the sftp protocol
version. |
| ! command |
Execute command in local shell. |
| ! |
Escape to local shell. |
| ? |
Synonym for help. |
Examples
sftp shell.computerhope.com
Typing the above command would connect to a secure
connection for transferring files. If the host you're using supports
a secure login you would then be connected to the host. Below is an
example of what would be seen.
Connecting to shell.computerhope.com...
Password:
sftp>
However, if the host does not support a secure
login, it's likely you would receive an error similar to the below
example.
Connecting to shell.computerhope.com...
ssh: shell.computerhope.com: Name or service not known
Couldn't read packet: Connection reset by peer
