It may also use many + features of ssh, such as public key authentication 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 automatically 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 specified. An optional trailing slash can be + used to force the path to be interpreted as a directory. + + 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 forward 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 transferred, 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 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 to + obviate the need to enter a password at connection time (see + sshd(8) and ssh-keygen(1) for details). + + A batchfile of M-bM-^@M-^X-M-bM-^@M-^Y 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 M-bM-^@M-^X-M-bM-^@M-^Y character (for example, + -rm /tmp/blah*). Echo of the command may be suppressed by + prefixing the command with a M-bM-^@M-^X@M-bM-^@M-^Y 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 directly 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 directly 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@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 described by destination and then establishing a + TCP forwarding to the ultimate destination from there. Multiple + jump hops may be specified separated by comma characters. This + is a shortcut to specify a ProxyJump configuration directive. + This option 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.

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 understand 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 escaped with + backslashes (M-bM-^@M-^X\M-bM-^@M-^Y). + + 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. If the -h flag is specified, + then symlinks will not be followed. path may contain glob(7) + characters and may match multiple files. grp must be a numeric + GID. + + chmod [-h] mode path + Change permissions of file path to mode. If the -h flag is + specified, then symlinks will not be followed. path may contain + glob(7) characters and may match multiple files. + + chown [-h] own path + Change owner of file path to own. If the -h flag is specified, + then symlinks will not be followed. path may contain glob(7) + characters and may match multiple files. own must be a numeric + UID. + + 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 displayed using "human-readable" + suffixes. The -i flag requests display of inode information in + addition to capacity information. This command is only supported + on servers that implement the M-bM-^@M-^\statvfs@openssh.comM-bM-^@M-^] 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 (M-bM-^@M-^X.M-bM-^@M-^Y). + + -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 numerically. + + -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@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. + + !
