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
1.40.2.2! brad 74: The third usage format allows the sftp client to start in a remote directory.
1.1 djm 75: .Pp
1.40.2.2! brad 76: The final usage format allows for automated sessions using the
! 77: .Fl b
! 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
! 81: .Xr sshd 8
! 82: and
! 83: .Xr ssh-keygen 1
! 84: for details).
1.1 djm 85: The options are as follows:
86: .Bl -tag -width Ds
1.10 deraadt 87: .It Fl b Ar batchfile
88: Batch mode reads a series of commands from an input
1.13 stevesk 89: .Ar batchfile
1.10 deraadt 90: instead of
1.13 stevesk 91: .Em stdin .
92: Since it lacks user interaction it should be used in conjunction with
93: non-interactive authentication.
94: .Nm
1.21 itojun 95: will abort if any of the following
96: commands fail:
1.33 deraadt 97: .Ic get , put , rename , ln ,
1.40.2.1 margarid 98: .Ic rm , mkdir , chdir , ls ,
1.39 djm 99: .Ic lchdir , chmod , chown , chgrp , lpwd
1.10 deraadt 100: and
1.13 stevesk 101: .Ic lmkdir .
1.40.2.1 margarid 102: Termination on error can be suppressed on a command by command basis by
103: prefixing the command with a
1.40.2.2! brad 104: .Sq Ic \-
! 105: character (for example,
! 106: .Ic -rm /tmp/blah* ) .
1.1 djm 107: .It Fl o Ar ssh_option
1.23 stevesk 108: Can be used to pass options to
109: .Nm ssh
1.35 stevesk 110: in the format used in
111: .Xr ssh_config 5 .
112: This is useful for specifying options
1.23 stevesk 113: for which there is no separate
114: .Nm sftp
1.40.2.2! brad 115: command-line flag.
! 116: For example, to specify an alternate port use:
1.26 stevesk 117: .Ic sftp -oPort=24 .
118: .It Fl s Ar subsystem | sftp_server
119: Specifies the SSH2 subsystem or the path for an sftp server
1.40.2.2! brad 120: on the remote host.
! 121: A path is useful for using
! 122: .Nm
! 123: over protocol version 1, or when the remote
! 124: .Xr sshd 8
1.26 stevesk 125: does not have an sftp subsystem configured.
1.29 markus 126: .It Fl v
1.40.2.2! brad 127: Raise logging level.
! 128: This option is also passed to ssh.
1.29 markus 129: .It Fl B Ar buffer_size
1.40.2.1 margarid 130: Specify the size of the buffer that
1.29 markus 131: .Nm
1.40.2.2! brad 132: uses when transferring files.
! 133: Larger buffers require fewer round trips at the cost of higher
! 134: memory consumption.
! 135: The default is 32768 bytes.
1.29 markus 136: .It Fl C
137: Enables compression (via ssh's
138: .Fl C
139: flag).
140: .It Fl F Ar ssh_config
141: Specifies an alternative
142: per-user configuration file for
1.40.2.2! brad 143: .Xr ssh 1 .
1.29 markus 144: This option is directly passed to
145: .Xr ssh 1 .
146: .It Fl P Ar sftp_server path
1.40.2.2! brad 147: Connect directly to a local sftp server
1.29 markus 148: (rather than via
1.40.2.2! brad 149: .Xr ssh 1 )
1.29 markus 150: This option may be useful in debugging the client and server.
1.30 djm 151: .It Fl R Ar num_requests
1.40.2.2! brad 152: Specify how many requests may be outstanding at any one time.
! 153: Increasing this may slightly improve file transfer speed
! 154: but will increase memory usage.
! 155: The default is 16 outstanding requests.
1.26 stevesk 156: .It Fl S Ar program
157: Name of the
158: .Ar program
159: to use for the encrypted connection.
160: The program must understand
161: .Xr ssh 1
162: options.
1.29 markus 163: .It Fl 1
164: Specify the use of protocol version 1.
1.1 djm 165: .El
166: .Sh INTERACTIVE COMMANDS
1.2 djm 167: Once in interactive mode,
168: .Nm
1.21 itojun 169: understands a set of commands similar to those of
1.1 djm 170: .Xr ftp 1 .
1.6 djm 171: Commands are case insensitive and pathnames may be enclosed in quotes if they
172: contain spaces.
