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

1.44 jmc 196: Specify how many requests may be outstanding at any one time.

1.46 jmc 207: .It Fl s Ar subsystem | sftp_server
208: Specifies the SSH2 subsystem or the path for an sftp server
209: on the remote host.
210: A path is useful for using
211: .Nm
212: over protocol version 1, or when the remote
213: .Xr sshd 8
214: does not have an sftp subsystem configured.
215: .It Fl v
216: Raise logging level.
217: This option is also passed to ssh.
