1.1 djm 61: .Sh DESCRIPTION
62: .Nm
63: is an interactive file transfer program, similar to
64: .Xr ftp 1 ,
65: which performs all operations over an encrypted
66: .Xr ssh 1
67: transport.
68: It may also use many features of ssh, such as public key authentication and
69: compression.
70: .Nm
71: connects and logs into the specified
1.18 stevesk 72: .Ar host ,
1.1 djm 73: then enters an interactive command mode.
1.15 mouring 74: .Pp
1.21 itojun 75: The second usage format will retrieve files automatically if a non-interactive
1.18 stevesk 76: authentication method is used; otherwise it will do so after
77: successful interactive authentication.
1.15 mouring 78: .Pp
1.60 jaredy 79: The third usage format allows
80: .Nm
81: to start in a remote directory.
1.1 djm 82: .Pp
1.44 jmc 83: The final usage format allows for automated sessions using the
1.42 djm 84: .Fl b
1.44 jmc 85: option.
1.62 jmc 86: In such cases, it is necessary to configure non-interactive authentication
1.44 jmc 87: to obviate the need to enter a password at connection time (see
1.42 djm 88: .Xr sshd 8
1.43 jmc 89: and
1.42 djm 90: .Xr ssh-keygen 1
1.44 jmc 91: for details).
1.89 djm 92: .Pp
93: Since some usage formats use colon characters to delimit host names from path
94: names, IPv6 addresses must be enclosed in square brackets to avoid ambiguity.
95: .Pp
1.1 djm 96: The options are as follows:
97: .Bl -tag -width Ds
1.46 jmc 98: .It Fl 1
99: Specify the use of protocol version 1.
1.70 djm 100: .It Fl 2
101: Specify the use of protocol version 2.
102: .It Fl 4
103: Forces
104: .Nm
105: to use IPv4 addresses only.
106: .It Fl 6
107: Forces
108: .Nm
109: to use IPv6 addresses only.
1.94 jmc 110: .It Fl a
1.99 jmc 111: Attempt to continue interrupted transfers rather than overwriting
1.98 logan 112: existing partial or complete copies of files.
1.99 jmc 113: If the partial contents differ from those being transferred,
1.98 logan 114: then the resultant file is likely to be corrupt.
1.46 jmc 115: .It Fl B Ar buffer_size
116: Specify the size of the buffer that
117: .Nm
118: uses when transferring files.
119: Larger buffers require fewer round trips at the cost of higher
120: memory consumption.
121: The default is 32768 bytes.
1.10 deraadt 122: .It Fl b Ar batchfile
123: Batch mode reads a series of commands from an input
1.13 stevesk 124: .Ar batchfile
1.10 deraadt 125: instead of
1.13 stevesk 126: .Em stdin .
127: Since it lacks user interaction it should be used in conjunction with
1.51 jmc 128: non-interactive authentication.
1.50 djm 129: A
1.51 jmc 130: .Ar batchfile
131: of
132: .Sq \-
1.50 djm 133: may be used to indicate standard input.
1.13 stevesk 134: .Nm
1.21 itojun 135: will abort if any of the following
136: commands fail:
1.98 logan 137: .Ic get , put , reget , reput, rename , ln ,
1.41 jmc 138: .Ic rm , mkdir , chdir , ls ,
1.66 jmc 139: .Ic lchdir , chmod , chown ,
1.88 djm 140: .Ic chgrp , lpwd , df , symlink ,
1.10 deraadt 141: and
1.13 stevesk 142: .Ic lmkdir .
1.41 jmc 143: Termination on error can be suppressed on a command by command basis by
144: prefixing the command with a
1.51 jmc 145: .Sq \-
1.44 jmc 146: character (for example,
147: .Ic -rm /tmp/blah* ) .
1.71 jmc 148: .It Fl C
149: Enables compression (via ssh's
150: .Fl C
151: flag).
1.70 djm 152: .It Fl c Ar cipher
153: Selects the cipher to use for encrypting the data transfers.
154: This option is directly passed to
155: .Xr ssh 1 .
1.72 djm 156: .It Fl D Ar sftp_server_path
157: Connect directly to a local sftp server
158: (rather than via

160: This option may be useful in debugging the client and server.
1.46 jmc 161: .It Fl F Ar ssh_config
162: Specifies an alternative
163: per-user configuration file for
164: .Xr ssh 1 .
165: This option is directly passed to
166: .Xr ssh 1 .
1.95 djm 167: .It Fl f
168: Requests that files be flushed to disk immediately after transfer.
169: When uploading files, this feature is only enabled if the server
170: implements the "fsync@openssh.com" extension.
1.70 djm 171: .It Fl i Ar identity_file
172: Selects the file from which the identity (private key) for public key
173: authentication is read.
174: This option is directly passed to
175: .Xr ssh 1 .
1.85 djm 176: .It Fl l Ar limit
177: Limits the used bandwidth, specified in Kbit/s.
1.1 djm 178: .It Fl o Ar ssh_option
1.23 stevesk 179: Can be used to pass options to
180: .Nm ssh
1.35 stevesk 181: in the format used in
182: .Xr ssh_config 5 .
183: This is useful for specifying options
1.23 stevesk 184: for which there is no separate
185: .Nm sftp
1.44 jmc 186: command-line flag.
187: For example, to specify an alternate port use:
1.26 stevesk 188: .Ic sftp -oPort=24 .
1.46 jmc 189: For full details of the options listed below, and their possible values, see

281: on the remote host.
282: A path is useful for using
