SFTP(1)                    OpenBSD Reference Manual                    SFTP(1) NAME      sftp - secure file transfer program SYNOPSIS      sftp [-1Cv] [-B buffer_size] [-b batchfile] [-F ssh_config]           [-o ssh_option] [-P sftp_server_path] [-R num_requests] [-S program]           [-s subsystem | sftp_server] host      sftp [user@]host[:file ...]      sftp [user@]host[:dir[/]]      sftp -b batchfile [user@]host DESCRIPTION      sftp is an interactive 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 authentication and compres-      sion.  sftp connects and logs into the specified host, then enters an in-      teractive command mode.      The second usage format will retrieve files automatically if a non-inter-      active authentication method is used; otherwise it will do so after suc-      cessful interactive authentication.      The third usage format allows sftp to start in a remote directory.      The final usage format allows for automated sessions using the -b option.      In such cases, it is necessary to configure non-interactive authentica-      tion to obviate the need to enter a password at connection time (see      sshd(8) and ssh-keygen(1) for details).  The options are as follows:      -1      Specify the use of protocol version 1.      -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 in-              stead of stdin.  Since it lacks user interaction it should be              used in conjunction with non-interactive authentication.  A              batchfile of `-' may be used to indicate standard input.  sftp              will abort if any of the following commands fail: get, put,              rename, ln, rm, mkdir, chdir, ls, lchdir, chmod, chown, chgrp,              lpwd, df, 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*).      -C      Enables compression (via ssh's -C flag).      -F ssh_config              Specifies an alternative per-user configuration file for ssh(1).              This option is directly passed to ssh(1).      -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).                    AddressFamily                    BatchMode                    BindAddress                    ChallengeResponseAuthentication                    CheckHostIP                    Cipher                    Ciphers                    Compression                    CompressionLevel                    ConnectionAttempts                    ConnectTimeout                    ControlMaster                    ControlPath                    GlobalKnownHostsFile                    GSSAPIAuthentication                    GSSAPIDelegateCredentials                    HashKnownHosts                    Host                    HostbasedAuthentication                    HostKeyAlgorithms                    HostKeyAlias                    HostName                    IdentityFile                    IdentitiesOnly                    KbdInteractiveDevices                    LogLevel                    MACs                    NoHostAuthenticationForLocalhost                    NumberOfPasswordPrompts                    PasswordAuthentication                    Port                    PreferredAuthentications                    Protocol                    ProxyCommand                    PubkeyAuthentication                    RekeyLimit                    RhostsRSAAuthentication                    RSAAuthentication                    SendEnv                    ServerAliveInterval                    ServerAliveCountMax                    SmartcardDevice                    StrictHostKeyChecking                    TCPKeepAlive                    UsePrivilegedPort                    User                    UserKnownHostsFile                    VerifyHostKeyDNS      -P 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.      -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.      -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 for using sftp over protocol              version 1, or when the remote sshd(8) does not have an sftp sub-              system 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 (`\').      bye     Quit sftp.      cd path              Change remote directory to path.      chgrp grp path              Change group of file path to grp.  path may contain glob(3) char-              acters and may match multiple files.  grp must be a numeric GID.      chmod mode path              Change permissions of file path to mode.  path may contain              glob(3) characters and may match multiple files.      chown own path              Change owner of file path to own.  path may contain glob(3) char-              acters 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 ``statvfs@openssh.com'' extension.      exit    Quit sftp.      get [-P] 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(3)              characters and may match multiple files.  If it does and local-              path is specified, then local-path must specify a directory.  If              the -P flag is specified, then full file permissions and access              times are copied too.      help    Display help text.      lcd path              Change local directory to path.      lls [ls-options [path]]              Display local directory listing of either path or current direc-              tory if path is not specified.  ls-options may contain any flags              supported by the local system's ls(1) command.  path may contain              glob(3) characters and may match multiple files.      lmkdir path              Create local directory specified by path.      ln oldpath newpath              Create a symbolic link from oldpath to newpath.      lpwd    Print local working directory.      ls [-1aflnrSt] [path]              Display a remote directory listing of either path or the current              directory if path is not specified.  path may contain glob(3)              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 lexi-                      cographical.              -l      Display additional details including permissions and own-                      ership 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 [-P] local-path [remote-path]              Upload local-path and store it on the remote machine.  If the re-              mote path name is not specified, it is given the same name it has              on the local machine.  local-path may contain glob(3) characters              and may match multiple files.  If it does and remote-path is              specified, then remote-path must specify a directory.  If the -P              flag is specified, then the file's full permission and access              time are copied too.      pwd     Display remote working directory.      quit    Quit sftp.      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.
