DESCRIPTION

14     sftp is a file transfer program, similar to ftp(1), which performs all
15     operations over an encrypted ssh(1) transport.  It may also use many fea‐
16     tures of ssh, such as public key authentication and compression.
17
18     The destination may be specified either as [user@]host[:path] or as a URI
19     in the form sftp://[user@]host[:port][/path].
20
21     If the destination includes a path and it is not a directory, sftp will
22     retrieve files automatically if a non-interactive authentication method
23     is used; otherwise it will do so after successful interactive authentica‐
24     tion.
25
26     If no path is specified, or if the path is a directory, sftp will log in
27     to the specified host and enter interactive command mode, changing to the
28     remote directory if one was specified.  An optional trailing slash can be
29     used to force the path to be interpreted as a directory.
30
31     Since the destination formats use colon characters to delimit host names
32     from path names or port numbers, IPv6 addresses must be enclosed in
33     square brackets to avoid ambiguity.
34
35     The options are as follows:
36
37     -4      Forces sftp to use IPv4 addresses only.
38
39     -6      Forces sftp to use IPv6 addresses only.
40
41     -A      Allows forwarding of ssh-agent(1) to the remote system.  The
42             default is not to forward an authentication agent.
43
44     -a      Attempt to continue interrupted transfers rather than overwriting
45             existing partial or complete copies of files.  If the partial
46             contents differ from those being transferred, then the resultant
47             file is likely to be corrupt.
48
49     -B buffer_size
50             Specify the size of the buffer that sftp uses when transferring
51             files.  Larger buffers require fewer round trips at the cost of
52             higher memory consumption.  The default is 32768 bytes.
53
54     -b batchfile
55             Batch mode reads a series of commands from an input batchfile
56             instead of stdin.  Since it lacks user interaction it should be
57             used in conjunction with non-interactive authentication to obvi‐
58             ate the need to enter a password at connection time (see sshd(8)
59             and ssh-keygen(1) for details).
60
61             A batchfile of ‘-’ may be used to indicate standard input.  sftp
62             will abort if any of the following commands fail: get, put,
63             reget, reput, rename, ln, rm, mkdir, chdir, ls, lchdir, chmod,
64             chown, chgrp, lpwd, df, symlink, and lmkdir.
65
66             Termination on error can be suppressed on a command by command
67             basis by prefixing the command with a ‘-’ character (for example,
68             -rm /tmp/blah*).  Echo of the command may be suppressed by pre‐
69             fixing the command with a ‘@’ character.  These two prefixes may
70             be combined in any order, for example -@ls /bsd.
71
72     -C      Enables compression (via ssh's -C flag).
73
74     -c cipher
75             Selects the cipher to use for encrypting the data transfers.
76             This option is directly passed to ssh(1).
77
78     -D sftp_server_path
79             Connect directly to a local sftp server (rather than via ssh(1)).
80             This option may be useful in debugging the client and server.
81
82     -F ssh_config
83             Specifies an alternative per-user configuration file for ssh(1).
84             This option is directly passed to ssh(1).
85
86     -f      Requests that files be flushed to disk immediately after trans‐
87             fer.  When uploading files, this feature is only enabled if the
88             server implements the "fsync@openssh.com" extension.
89
90     -i identity_file
91             Selects the file from which the identity (private key) for public
92             key authentication is read.  This option is directly passed to
93             ssh(1).
94
95     -J destination
96             Connect to the target host by first making an sftp connection to
97             the jump host described by destination and then establishing a
98             TCP forwarding to the ultimate destination from there.  Multiple
99             jump hops may be specified separated by comma characters.  This
100             is a shortcut to specify a ProxyJump configuration directive.
101             This option is directly passed to ssh(1).
102
103     -l limit
104             Limits the used bandwidth, specified in Kbit/s.
105
106     -N      Disables quiet mode, e.g. to override the implicit quiet mode set
107             by the -b flag.
108
109     -o ssh_option
110             Can be used to pass options to ssh in the format used in
111             ssh_config(5).  This is useful for specifying options for which
112             there is no separate sftp command-line flag.  For example, to
113             specify an alternate port use: sftp -oPort=24.  For full details
114             of the options listed below, and their possible values, see
115             ssh_config(5).

177
178     -P port
179             Specifies the port to connect to on the remote host.
180
181     -p      Preserves modification times, access times, and modes from the
182             original files transferred.
183
184     -q      Quiet mode: disables the progress meter as well as warning and
185             diagnostic messages from ssh(1).
186
187     -R num_requests
188             Specify how many requests may be outstanding at any one time.
189             Increasing this may slightly improve file transfer speed but will
190             increase memory usage.  The default is 256 outstanding requests
191             providing for 8MB of outstanding data with a 32KB buffer.
192
193     -r      Recursively copy entire directories when uploading and download‐
194             ing.  Note that sftp does not follow symbolic links encountered
195             in the tree traversal.
196
197     -S program
198             Name of the program to use for the encrypted connection.  The
199             program must understand ssh(1) options.
200
201     -s subsystem | sftp_server
202             Specifies the SSH2 subsystem or the path for an sftp server on
203             the remote host.  A path is useful when the remote sshd(8) does
204             not have an sftp subsystem configured.
205
206     -v      Raise logging level.  This option is also passed to ssh.
207

INTERACTIVE COMMANDS

209     Once in interactive mode, sftp understands a set of commands similar to
210     those of ftp(1).  Commands are case insensitive.  Pathnames that contain
211     spaces must be enclosed in quotes.  Any special characters contained
212     within pathnames that are recognized by glob(3) must be escaped with
213     backslashes (‘\’).
214
215     bye     Quit sftp.
216
217     cd [path]
218             Change remote directory to path.  If path is not specified, then
219             change directory to the one the session started in.
220
221     chgrp [-h] grp path
222             Change group of file path to grp.  If the -h flag is specified,
223             then symlinks will not be followed.  path may contain glob(7)
224             characters and may match multiple files.  grp must be a numeric
225             GID.
226
227     chmod [-h] mode path
228             Change permissions of file path to mode.  If the -h flag is spec‐
229             ified, then symlinks will not be followed.  path may contain
230             glob(7) characters and may match multiple files.
231
232     chown [-h] own path
233             Change owner of file path to own.  If the -h flag is specified,
234             then symlinks will not be followed.  path may contain glob(7)
235             characters and may match multiple files.  own must be a numeric
236             UID.
237
238     df [-hi] [path]
239             Display usage information for the filesystem holding the current
240             directory (or path if specified).  If the -h flag is specified,
241             the capacity information will be displayed using "human-readable"
242             suffixes.  The -i flag requests display of inode information in
243             addition to capacity information.  This command is only supported
244             on servers that implement the “statvfs@openssh.com” extension.
245
246     exit    Quit sftp.
247
248     get [-afpR] remote-path [local-path]
249             Retrieve the remote-path and store it on the local machine.  If
250             the local path name is not specified, it is given the same name
251             it has on the remote machine.  remote-path may contain glob(7)
252             characters and may match multiple files.  If it does and
253             local-path is specified, then local-path must specify a direc‐
254             tory.
255
256             If the -a flag is specified, then attempt to resume partial
257             transfers of existing files.  Note that resumption assumes that
258             any partial copy of the local file matches the remote copy.  If
259             the remote file contents differ from the partial local copy then
260             the resultant file is likely to be corrupt.
261
262             If the -f flag is specified, then fsync(2) will be called after
263             the file transfer has completed to flush the file to disk.
264
265             If the -p flag is specified, then full file permissions and
266             access times are copied too.
267
268             If the -R flag is specified then directories will be copied
269             recursively.  Note that sftp does not follow symbolic links when
270             performing recursive transfers.
271
272     help    Display help text.
273
274     lcd [path]
275             Change local directory to path.  If path is not specified, then
276             change directory to the local user's home directory.
277
278     lls [ls-options [path]]
279             Display local directory listing of either path or current direc‐
280             tory if path is not specified.  ls-options may contain any flags
281             supported by the local system's ls(1) command.  path may contain
282             glob(7) characters and may match multiple files.
283
284     lmkdir path
285             Create local directory specified by path.
286
287     ln [-s] oldpath newpath
288             Create a link from oldpath to newpath.  If the -s flag is speci‐
289             fied the created link is a symbolic link, otherwise it is a hard
290             link.
291
292     lpwd    Print local working directory.
293
294     ls [-1afhlnrSt] [path]
295             Display a remote directory listing of either path or the current
296             directory if path is not specified.  path may contain glob(7)
297             characters and may match multiple files.
298
299             The following flags are recognized and alter the behaviour of ls
300             accordingly:
301
302             -1      Produce single columnar output.
303
304             -a      List files beginning with a dot (‘.’).
305
306             -f      Do not sort the listing.  The default sort order is lexi‐
307                     cographical.
308
309             -h      When used with a long format option, use unit suffixes:
310                     Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Petabyte,
311                     and Exabyte in order to reduce the number of digits to
312                     four or fewer using powers of 2 for sizes (K=1024,
313                     M=1048576, etc.).
314
315             -l      Display additional details including permissions and own‐
316                     ership information.
317
318             -n      Produce a long listing with user and group information
319                     presented numerically.
320
321             -r      Reverse the sort order of the listing.
322
323             -S      Sort the listing by file size.
324
325             -t      Sort the listing by last modification time.
326
327     lumask umask
328             Set local umask to umask.
329
330     mkdir path
331             Create remote directory specified by path.
332
333     progress
334             Toggle display of progress meter.
335
336     put [-afpR] local-path [remote-path]
337             Upload local-path and store it on the remote machine.  If the
338             remote path name is not specified, it is given the same name it
339             has on the local machine.  local-path may contain glob(7) charac‐
340             ters and may match multiple files.  If it does and remote-path is
341             specified, then remote-path must specify a directory.
342
343             If the -a flag is specified, then attempt to resume partial
344             transfers of existing files.  Note that resumption assumes that
345             any partial copy of the remote file matches the local copy.  If
346             the local file contents differ from the remote local copy then
347             the resultant file is likely to be corrupt.
348
349             If the -f flag is specified, then a request will be sent to the
350             server to call fsync(2) after the file has been transferred.
351             Note that this is only supported by servers that implement the
352             "fsync@openssh.com" extension.
353
354             If the -p flag is specified, then full file permissions and
355             access times are copied too.
356
357             If the -R flag is specified then directories will be copied
358             recursively.  Note that sftp does not follow symbolic links when
359             performing recursive transfers.
360
361     pwd     Display remote working directory.
362
