55 is an interactive file transfer program, similar to
57 which performs all operations over an encrypted
60 It may also use many features of ssh, such as public key authentication and
63 connects and logs into the specified
65 then enters an interactive command mode.
67 The second usage format will retrieve files automatically if a non-interactive
68 authentication method is used; otherwise it will do so after
69 successful interactive authentication.
71 The last usage format allows the sftp client to start in a remote directory.
73 The options are as follows:
76 Batch mode reads a series of commands from an input
80 Since it lacks user interaction it should be used in conjunction with
81 non-interactive authentication.
83 will abort if any of the following
85 .Ic get , put , rename , ln ,
86 .Ic rm , mkdir , chdir , ls ,
87 .Ic lchdir , chmod , chown , chgrp , lpwd

91 prefixing the command with a

107 .It Fl s Ar subsystem | sftp_server
108 Specifies the SSH2 subsystem or the path for an sftp server

115 .It Fl B Ar buffer_size
116 Specify the size of the buffer that
