1.1 djm 56: .Sh DESCRIPTION
57: .Nm
58: is an interactive file transfer program, similar to
59: .Xr ftp 1 ,
60: which performs all operations over an encrypted
61: .Xr ssh 1
62: transport.
63: It may also use many features of ssh, such as public key authentication and
64: compression.
65: .Nm
66: connects and logs into the specified
1.18 stevesk 67: .Ar host ,
1.1 djm 68: then enters an interactive command mode.
1.15 mouring 69: .Pp
1.21 itojun 70: The second usage format will retrieve files automatically if a non-interactive
1.18 stevesk 71: authentication method is used; otherwise it will do so after
72: successful interactive authentication.
1.15 mouring 73: .Pp
1.60 jaredy 74: The third usage format allows
75: .Nm
76: to start in a remote directory.
1.1 djm 77: .Pp
1.44 jmc 78: The final usage format allows for automated sessions using the
1.42 djm 79: .Fl b
1.44 jmc 80: option.
1.62 ! jmc 81: In such cases, it is necessary to configure non-interactive authentication
1.44 jmc 82: to obviate the need to enter a password at connection time (see
1.42 djm 83: .Xr sshd 8
1.43 jmc 84: and
1.42 djm 85: .Xr ssh-keygen 1
1.44 jmc 86: for details).
1.1 djm 87: The options are as follows:
88: .Bl -tag -width Ds
1.46 jmc 89: .It Fl 1
90: Specify the use of protocol version 1.
91: .It Fl B Ar buffer_size
92: Specify the size of the buffer that
93: .Nm
94: uses when transferring files.
95: Larger buffers require fewer round trips at the cost of higher
96: memory consumption.
97: The default is 32768 bytes.
1.10 deraadt 98: .It Fl b Ar batchfile
99: Batch mode reads a series of commands from an input
1.13 stevesk 100: .Ar batchfile
1.10 deraadt 101: instead of
1.13 stevesk 102: .Em stdin .
103: Since it lacks user interaction it should be used in conjunction with
1.51 jmc 104: non-interactive authentication.
1.50 djm 105: A
1.51 jmc 106: .Ar batchfile
107: of
108: .Sq \-
1.50 djm 109: may be used to indicate standard input.
1.13 stevesk 110: .Nm
1.21 itojun 111: will abort if any of the following
112: commands fail:
1.33 deraadt 113: .Ic get , put , rename , ln ,
1.41 jmc 114: .Ic rm , mkdir , chdir , ls ,
1.39 djm 115: .Ic lchdir , chmod , chown , chgrp , lpwd
1.10 deraadt 116: and
1.13 stevesk 117: .Ic lmkdir .
1.41 jmc 118: Termination on error can be suppressed on a command by command basis by
119: prefixing the command with a
1.51 jmc 120: .Sq \-
1.44 jmc 121: character (for example,
122: .Ic -rm /tmp/blah* ) .
1.46 jmc 123: .It Fl C
124: Enables compression (via ssh's
125: .Fl C
126: flag).
127: .It Fl F Ar ssh_config
128: Specifies an alternative
129: per-user configuration file for
130: .Xr ssh 1 .
131: This option is directly passed to
132: .Xr ssh 1 .
1.1 djm 133: .It Fl o Ar ssh_option
1.23 stevesk 134: Can be used to pass options to
135: .Nm ssh
1.35 stevesk 136: in the format used in
137: .Xr ssh_config 5 .
138: This is useful for specifying options
1.23 stevesk 139: for which there is no separate
140: .Nm sftp
1.44 jmc 141: command-line flag.
142: For example, to specify an alternate port use:
1.26 stevesk 143: .Ic sftp -oPort=24 .
1.46 jmc 144: For full details of the options listed below, and their possible values, see

1.29 markus 200: This option may be useful in debugging the client and server.
1.30 djm 201: .It Fl R Ar num_requests
1.44 jmc 202: Specify how many requests may be outstanding at any one time.
203: Increasing this may slightly improve file transfer speed
204: but will increase memory usage.

1.46 jmc 213: .It Fl s Ar subsystem | sftp_server
214: Specifies the SSH2 subsystem or the path for an sftp server
215: on the remote host.
216: A path is useful for using

219: .Xr sshd 8
220: does not have an sftp subsystem configured.
221: .It Fl v
