49 is an interactive file transfer program, similar to
51 which performs all operations over an encrypted
54 It may also use many features of ssh, such as public key authentication and
57 connects and logs into the specified
59 then enters an interactive command mode.
61 The second usage format will retrieve files automatically if a non-interactive
62 authentication method is used; otherwise it will do so after
63 successful interactive authentication.
65 The last usage format allows the sftp client to start in a remote directory.
67 The options are as follows:
70 Batch mode reads a series of commands from an input
74 Since it lacks user interaction it should be used in conjunction with
75 non-interactive authentication.

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

101 .It Fl B Ar buffer_size
102 Specify the size of the buffer that
