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).

176                   VerifyHostKeyDNS
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 64 outstanding requests.
191
192     -r      Recursively copy entire directories when uploading and download‐
193             ing.  Note that sftp does not follow symbolic links encountered
194             in the tree traversal.
195
196     -S program
197             Name of the program to use for the encrypted connection.  The
198             program must understand ssh(1) options.
199
200     -s subsystem | sftp_server
201             Specifies the SSH2 subsystem or the path for an sftp server on
202             the remote host.  A path is useful when the remote sshd(8) does
203             not have an sftp subsystem configured.
204
205     -v      Raise logging level.  This option is also passed to ssh.
206

INTERACTIVE COMMANDS

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