SFTP(1) BSD General Commands Manual SFTP(1)
NAME
sftp -- OpenSSH secure file transfer
SYNOPSIS
sftp [-46AaCfNpqrv] [-B buffer_size] [-b batchfile] [-c cipher] [-D sftp_server_path]
[-F ssh_config] [-i identity_file] [-J destination] [-l limit] [-o ssh_option]
[-P port] [-R num_requests] [-S program] [-s subsystem | sftp_server] destination
DESCRIPTION
sftp is a 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 au-
thentication and compression.
The destination may be specified either as [user@]host[:path] or as a URI in the form
sftp://[user@]host[:port][/path].
If the destination includes a path and it is not a directory, sftp will retrieve files auto-
matically if a non-interactive authentication method is used; otherwise it will do so after
successful interactive authentication.
If no path is specified, or if the path is a directory, sftp will log in to the specified
host and enter interactive command mode, changing to the remote directory if one was speci-
fied. An optional trailing slash can be used to force the path to be interpreted as a di-
rectory.
Since the destination formats use colon characters to delimit host names from path names or
port numbers, IPv6 addresses must be enclosed in square brackets to avoid ambiguity.
The options are as follows:
-4 Forces sftp to use IPv4 addresses only.
-6 Forces sftp to use IPv6 addresses only.
-A Allows forwarding of ssh-agent(1) to the remote system. The default is not to for-
ward an authentication agent.
-a Attempt to continue interrupted transfers rather than overwriting existing partial
or complete copies of files. If the partial contents differ from those being trans-
ferred, then the resultant file is likely to be corrupt.
-B buffer_size
Specify the size of the buffer that sftp uses when transferring files. Larger buf-
fers require fewer round trips at the cost of higher memory consumption. The de-
fault 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-interac-
tive authentication to obviate the need to enter a password at connection time (see
sshd(8) and ssh-keygen(1) for details).
A batchfile of '-' may be used to indicate standard input. sftp will abort if any
of the following commands fail: get, put, reget, reput, rename, ln, rm, mkdir,
chdir, ls, lchdir, chmod, chown, chgrp, lpwd, df, symlink, 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*). Echo of the command
may be suppressed by prefixing the command with a '@' character. These two prefixes
may be combined in any order, for example -@ls /bsd.
-C Enables compression (via ssh's -C flag).
-c cipher
Selects the cipher to use for encrypting the data transfers. This option is di-
rectly passed to ssh(1).
-D sftp_server_path
Connect directly to a local sftp server (rather than via ssh(1)). This option may
be useful in debugging the client and server.
-F ssh_config
Specifies an alternative per-user configuration file for ssh(1). This option is di-
rectly passed to ssh(1).
-f Requests that files be flushed to disk immediately after transfer. When uploading
files, this feature is only enabled if the server implements the "fsync AT openssh.com"
extension.
-i identity_file
Selects the file from which the identity (private key) for public key authentication
is read. This option is directly passed to ssh(1).
-J destination
Connect to the target host by first making an sftp connection to the jump host de-
scribed by destination and then establishing a TCP forwarding to the ultimate desti-
nation from there. Multiple jump hops may be specified separated by comma charac-
ters. This is a shortcut to specify a ProxyJump configuration directive. This op-
tion is directly passed to ssh(1).
-l limit
Limits the used bandwidth, specified in Kbit/s.
-N Disables quiet mode, e.g. to override the implicit quiet mode set by the -b flag.
-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 port
Specifies the port to connect to on the remote host.
-p Preserves modification times, access times, and modes from the original files trans-
ferred.
-q Quiet mode: disables the progress meter as well as warning and diagnostic messages
from ssh(1).
-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
64 outstanding requests.
-r Recursively copy entire directories when uploading and downloading. Note that sftp
does not follow symbolic links encountered in the tree traversal.
-S program
Name of the program to use for the encrypted connection. The program must under-
stand ssh(1) options.
-s subsystem | sftp_server
Specifies the SSH2 subsystem or the path for an sftp server on the remote host. A
path is useful when the remote sshd(8) does not have an sftp subsystem configured.
-v Raise logging level. This option is also passed to ssh.
INTERACTIVE COMMANDS
Once in interactive mode, sftp understands a set of commands similar to those of ftp(1).
Commands are case insensitive. Pathnames that contain spaces must be enclosed in quotes.
Any special characters contained within pathnames that are recognized by glob(3) must be es-
caped with backslashes ('\').
bye Quit sftp.
cd [path]
Change remote directory to path. If path is not specified, then change directory to
the one the session started in.
chgrp [-h] grp path
Change group of file path to grp. path may contain glob(7) characters and may match
multiple files. grp must be a numeric GID.
If the -h flag is specified, then symlinks will not be followed. Note that this is
only supported by servers that implement the "lsetstat AT openssh.com" extension.
chmod [-h] mode path
Change permissions of file path to mode. path may contain glob(7) characters and
may match multiple files.
If the -h flag is specified, then symlinks will not be followed. Note that this is
only supported by servers that implement the "lsetstat AT openssh.com" extension.
chown [-h] own path
Change owner of file path to own. path may contain glob(7) characters and may match
multiple files. own must be a numeric UID.
If the -h flag is specified, then symlinks will not be followed. Note that this is
only supported by servers that implement the "lsetstat AT openssh.com" extension.
df [-hi] [path]
Display usage information for the filesystem holding the current directory (or path
if specified). If the -h flag is specified, the capacity information will be dis-
played using "human-readable" suffixes. The -i flag requests display of inode in-
formation in addition to capacity information. This command is only supported on
servers that implement the "statvfs AT openssh.com" extension.
exit Quit sftp.
get [-afpR] 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.
remote-path may contain glob(7) characters and may match multiple files. If it does
and local-path is specified, then local-path must specify a directory.
If the -a flag is specified, then attempt to resume partial transfers of existing
files. Note that resumption assumes that any partial copy of the local file matches
the remote copy. If the remote file contents differ from the partial local copy
then the resultant file is likely to be corrupt.
If the -f flag is specified, then fsync(2) will be called after the file transfer
has completed to flush the file to disk.
If the -p flag is specified, then full file permissions and access times are copied
too.
If the -R flag is specified then directories will be copied recursively. Note that
sftp does not follow symbolic links when performing recursive transfers.
help Display help text.
lcd [path]
Change local directory to path. If path is not specified, then change directory to
the local user's home directory.
lls [ls-options [path]]
Display local directory listing of either path or current directory if path is not
specified. ls-options may contain any flags supported by the local system's ls(1)
command. path may contain glob(7) characters and may match multiple files.
lmkdir path
Create local directory specified by path.
ln [-s] oldpath newpath
Create a link from oldpath to newpath. If the -s flag is specified the created link
is a symbolic link, otherwise it is a hard link.
lpwd Print local working directory.
ls [-1afhlnrSt] [path]
Display a remote directory listing of either path or the current directory if path
is not specified. path may contain glob(7) characters and may match multiple files.
The following flags are recognized and alter the behaviour of ls accordingly:
-1 Produce single columnar output.
-a List files beginning with a dot ('.').
-f Do not sort the listing. The default sort order is lexicographical.
-h When used with a long format option, use unit suffixes: Byte, Kilobyte,
Megabyte, Gigabyte, Terabyte, Petabyte, and Exabyte in order to reduce the
number of digits to four or fewer using powers of 2 for sizes (K=1024,
M=1048576, etc.).
-l Display additional details including permissions and ownership information.
-n Produce a long listing with user and group information presented numeri-
cally.
-r Reverse the sort order of the listing.
-S Sort the listing by file size.
-t Sort the listing by last modification time.
lumask umask
Set local umask to umask.
mkdir path
Create remote directory specified by path.
progress
Toggle display of progress meter.
put [-afpR] 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. local-path
may contain glob(7) characters and may match multiple files. If it does and
remote-path is specified, then remote-path must specify a directory.
If the -a flag is specified, then attempt to resume partial transfers of existing
files. Note that resumption assumes that any partial copy of the remote file
matches the local copy. If the local file contents differ from the remote local
copy then the resultant file is likely to be corrupt.
If the -f flag is specified, then a request will be sent to the server to call
fsync(2) after the file has been transferred. Note that this is only supported by
servers that implement the "fsync AT openssh.com" extension.
If the -p flag is specified, then full file permissions and access times are copied
too.
If the -R flag is specified then directories will be copied recursively. Note that
sftp does not follow symbolic links when performing recursive transfers.
pwd Display remote working directory.
quit Quit sftp.
reget [-fpR] remote-path [local-path]
Resume download of remote-path. Equivalent to get with the -a flag set.
reput [-fpR] local-path [remote-path]
Resume upload of local-path. Equivalent to put with the -a flag set.
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.
