58 is an interactive file transfer program, similar to
60 which performs all operations over an encrypted
63 It may also use many features of ssh, such as public key authentication and
66 connects and logs into the specified
68 then enters an interactive command mode.
70 The second usage format will retrieve files automatically if a non-interactive
71 authentication method is used; otherwise it will do so after
72 successful interactive authentication.
74 The third usage format allows the sftp client to start in a remote directory.
76 The final usage form allows for automated sessions using the
78 option. In such cases, it is usually necessary to configure public key
79 authentication to obviate the need to enter a password at connection
85 The options are as follows:
88 Batch mode reads a series of commands from an input
92 Since it lacks user interaction it should be used in conjunction with
93 non-interactive authentication.

119 .It Fl s Ar subsystem | sftp_server
120 Specifies the SSH2 subsystem or the path for an sftp server
121 on the remote host. A path is useful for using sftp over

127 .It Fl B Ar buffer_size
128 Specify the size of the buffer that
