48 is an interactive file transfer program, similar to
50 which performs all operations over an encrypted
53 It may also use many features of ssh, such as public key authentication and
56 connects and logs into the specified
58 then enters an interactive command mode.
60 The second usage format will retrieve files automatically if a non-interactive
61 authentication method is used; otherwise it will do so after
62 successful interactive authentication.
64 The last usage format allows the sftp client to start in a remote directory.
66 The options are as follows:
69 Specify the use of protocol version 1.
70 .It Fl B Ar buffer_size
71 Specify the size of the buffer that
73 uses when transferring files. Larger buffers require fewer round trips at
74 the cost of higher memory consumption. The default is 32768 bytes.
75 .It Fl P Ar sftp_server path
76 Connect directly to a local
80 This option may be useful in debugging the client and server.
82 Batch mode reads a series of commands from an input
86 Since it lacks user interaction it should be used in conjunction with
87 non-interactive authentication.
