It may also use many features of ssh, such as public key authentica‐\ntion and compression.\n\nThe destination may be specified either as [user@]host[:path] or as a URI in the form\nsftp://[user@]host[:port][/path].\n\nIf the destination includes a path and it is not a directory, sftp will retrieve files automat‐\nically if a non-interactive authentication method is used; otherwise it will do so after suc‐\ncessful interactive authentication.\n\nIf no path is specified, or if the path is a directory, sftp will log in to the specified host\nand enter interactive command mode, changing to the remote directory if one was specified.  An\noptional trailing slash can be used to force the path to be interpreted as a directory.\n\nSince the destination formats use colon characters to delimit host names from path names or\nport numbers, IPv6 addresses must be enclosed in square brackets to avoid ambiguity.\n\nThe options are as follows:\n\n#### -4\n\n#### -6\n\n#### -A\n\nan authentication agent.\n\n#### -a\n\ncomplete copies of files.  If the partial contents differ from those being transferred,\nthen the resultant file is likely to be corrupt.\n\n#### -B\n\nSpecify the size of the buffer that sftp uses when transferring files.  Larger buffers\nrequire fewer round trips at the cost of higher memory consumption.  The default is\n32768 bytes.\n\n#### -b\n\nBatch mode reads a series of commands from an input batchfile instead of stdin.  Since\nit lacks user interaction it should be used in conjunction with non-interactive authen‐\ntication to obviate the need to enter a password at connection time (see sshd(8) and\nssh-keygen(1) for details).\n\nA batchfile of ‘-’ may be used to indicate standard input.  sftp will abort if any of\nthe following commands fail: get, put, reget, reput, rename, ln, rm, mkdir, chdir, ls,\nlchdir, chmod, chown, chgrp, lpwd, df, symlink, and lmkdir.\n\nTermination on error can be suppressed on a command by command basis by prefixing the\ncommand with a ‘-’ character (for example, -rm /tmp/blah*).  Echo of the command may be\nsuppressed by prefixing the command with a ‘@’ character.  These two prefixes may be\ncombined in any order, for example -@ls /bsd.\n\n#### -C -C\n\n#### -c\n\nSelects the cipher to use for encrypting the data transfers.  This option is directly\npassed to ssh(1).\n\n#### -D\n\nConnect directly to a local sftp server (rather than via ssh(1)).  This option may be\nuseful in debugging the client and server.\n\n#### -F\n\nSpecifies an alternative per-user configuration file for ssh(1).  This option is di‐\nrectly passed to ssh(1).\n\n#### -f\n\nfiles, this feature is only enabled if the server implements the \"fsync@openssh.com\"\nextension.\n\n#### -i\n\nSelects the file from which the identity (private key) for public key authentication is\nread.  This option is directly passed to ssh(1).\n\n#### -J\n\nConnect to the target host by first making an sftp connection to the jump host de‐\nscribed by destination and then establishing a TCP forwarding to the ultimate destina‐\ntion from there.  Multiple jump hops may be specified separated by comma characters.\nThis is a shortcut to specify a ProxyJump configuration directive.  This option is di‐\nrectly passed to ssh(1).\n\n#### -l\n\nLimits the used bandwidth, specified in Kbit/s.\n\n#### -N -b\n\n#### -o\n\nCan be used to pass options to ssh in the format used in sshconfig(5).  This is useful\nfor specifying options for which there is no separate sftp command-line flag.  For ex‐\nample, to specify an alternate port use: sftp -oPort=24.

Increasing this may\nslightly improve file transfer speed but will increase memory usage.  The default is 64\noutstanding requests.\n\n#### -r\n\ndoes not follow symbolic links encountered in the tree traversal.\n\n#### -S\n\nName of the program to use for the encrypted connection.  The program must understand\nssh(1) options.\n\n#### -s\n\nSpecifies the SSH2 subsystem or the path for an sftp server on the remote host.  A path\nis useful when the remote sshd(8) does not have an sftp subsystem configured.\n\n#### -v\n\n### INTERACTIVE COMMANDS\n\nOnce in interactive mode, sftp understands a set of commands similar to those of ftp(1).  Com‐\nmands are case insensitive.  Pathnames that contain spaces must be enclosed in quotes.  Any\nspecial characters contained within pathnames that are recognized by glob(3) must be escaped\nwith backslashes (‘\\’).\n\nbye     Quit sftp.\n\ncd [path]\nChange remote directory to path.  If path is not specified, then change directory to\nthe one the session started in.\n\nchgrp [-h] grp path\nChange group of file path to grp.  path may contain glob(7) characters and may match\nmultiple files.  grp must be a numeric GID.\n\nIf the -h flag is specified, then symlinks will not be followed.  Note that this is\nonly supported by servers that implement the \"lsetstat@openssh.com\" extension.\n\nchmod [-h] mode path\nChange permissions of file path to mode.  path may contain glob(7) characters and may\nmatch multiple files.\n\nIf the -h flag is specified, then symlinks will not be followed.  Note that this is\nonly supported by servers that implement the \"lsetstat@openssh.com\" extension.\n\nchown [-h] own path\nChange owner of file path to own.  path may contain glob(7) characters and may match\nmultiple files.  own must be a numeric UID.\n\nIf the -h flag is specified, then symlinks will not be followed.  Note that this is\nonly supported by servers that implement the \"lsetstat@openssh.com\" extension.\n\ndf [-hi] [path]\nDisplay usage information for the filesystem holding the current directory (or path if\nspecified).  If the -h flag is specified, the capacity information will be displayed\nusing \"human-readable\" suffixes.  The -i flag requests display of inode information in\naddition to capacity information.  This command is only supported on servers that im‐\nplement the “statvfs@openssh.com” extension.\n\nexit    Quit sftp.\n\nget [-afpR] remote-path [local-path]\nRetrieve the remote-path and store it on the local machine.  If the local path name is\nnot specified, it is given the same name it has on the remote machine.  remote-path may\ncontain glob(7) characters and may match multiple files.  If it does and local-path is\nspecified, then local-path must specify a directory.\n\nIf the -a flag is specified, then attempt to resume partial transfers of existing\nfiles.  Note that resumption assumes that any partial copy of the local file matches\nthe remote copy.  If the remote file contents differ from the partial local copy then\nthe resultant file is likely to be corrupt.\n\nIf the -f flag is specified, then fsync(2) will be called after the file transfer has\ncompleted to flush the file to disk.\n\nIf the -p flag is specified, then full file permissions and access times are copied\ntoo.\n\nIf the -R flag is specified then directories will be copied recursively.  Note that\nsftp does not follow symbolic links when performing recursive transfers.\n\nhelp    Display help text.\n\nlcd [path]\nChange local directory to path.  If path is not specified, then change directory to the\nlocal user's home directory.\n\nlls [ls-options [path]]\nDisplay local directory listing of either path or current directory if path is not\nspecified.  ls-options may contain any flags supported by the local system's ls(1) com‐\nmand.  path may contain glob(7) characters and may match multiple files.\n\nlmkdir path\nCreate local directory specified by path.\n\nln [-s] oldpath newpath\nCreate a link from oldpath to newpath.  If the -s flag is specified the created link is\na symbolic link, otherwise it is a hard link.\n\nlpwd    Print local working directory.\n\nls [-1afhlnrSt] [path]\nDisplay a remote directory listing of either path or the current directory if path is\nnot specified.  path may contain glob(7) characters and may match multiple files.\n\nThe following flags are recognized and alter the behaviour of ls accordingly:\n\n-1      Produce single columnar output.\n\n-a      List files beginning with a dot (‘.’).\n\n-f      Do not sort the listing.  The default sort order is lexicographical.\n\n-h      When used with a long format option, use unit suffixes: Byte, Kilobyte,\nMegabyte, Gigabyte, Terabyte, Petabyte, and Exabyte in order to reduce the num‐\nber of digits to four or fewer using powers of 2 for sizes (K=1024, M=1048576,\netc.).\n\n-l      Display additional details including permissions and ownership information.\n\n-n      Produce a long listing with user and group information presented numerically.\n\n-r      Reverse the sort order of the listing.\n\n-S      Sort the listing by file size.\n\n-t      Sort the listing by last modification time.\n\nlumask umask\nSet local umask to umask.\n\nmkdir path\nCreate remote directory specified by path.\n\n#### progress\n\nToggle display of progress meter.\n\nput [-afpR] local-path [remote-path]\nUpload local-path and store it on the remote machine.  If the remote path name is not\nspecified, it is given the same name it has on the local machine.  local-path may con‐\ntain glob(7) characters and may match multiple files.  If it does and remote-path is\nspecified, then remote-path must specify a directory.\n\nIf the -a flag is specified, then attempt to resume partial transfers of existing\nfiles.  Note that resumption assumes that any partial copy of the remote file matches\nthe local copy.  If the local file contents differ from the remote local copy then the\nresultant file is likely to be corrupt.\n\nIf the -f flag is specified, then a request will be sent to the server to call fsync(2)\nafter the file has been transferred.  Note that this is only supported by servers that\nimplement the \"fsync@openssh.com\" extension.\n\nIf the -p flag is specified, then full file permissions and access times are copied\ntoo.\n\nIf the -R flag is specified then directories will be copied recursively.  Note that\nsftp does not follow symbolic links when performing recursive transfers.\n\npwd     Display remote working directory.\n\nquit    Quit sftp.\n\nreget [-fpR] remote-path [local-path]\nResume download of remote-path.  Equivalent to get with the -a flag set.\n\nreput [-fpR] local-path [remote-path]\nResume upload of local-path.  Equivalent to put with the -a flag set.\n\nrename oldpath newpath\nRename remote file from oldpath to newpath.\n\nrm path\nDelete remote file specified by path.\n\nrmdir path\nRemove remote directory specified by path.\n\nsymlink oldpath newpath\nCreate a symbolic link from oldpath to newpath.\n\n#### version\n\nDisplay the sftp protocol version.\n\n!command\nExecute command in local shell.\n\n!       Escape to local shell.\n\n?       Synonym for help.\n\n### SEE ALSO\n\nftp(1), ls(1), scp(1), ssh(1), ssh-add(1), ssh-keygen(1), sshconfig(5), glob(7),\nsftp-server(8), sshd(8)\n\nT. Ylonen and S.
