1.7 aaron 44: .Sh DESCRIPTION
1.3 aaron 45: .Nm
1.6 aaron 46: copies files between hosts on a network.
47: It uses
1.3 aaron 48: .Xr ssh 1
1.1 deraadt 49: for data transfer, and uses the same authentication and provides the
50: same security as
1.3 aaron 51: .Xr ssh 1 .
1.1 deraadt 52: Unlike
1.3 aaron 53: .Xr rcp 1 ,
54: .Nm
1.1 deraadt 55: will ask for passwords or passphrases if they are needed for
56: authentication.
1.3 aaron 57: .Pp
1.44 jmc 58: File names may contain a user and host specification to indicate
1.6 aaron 59: that the file is to be copied to/from that host.
1.44 jmc 60: Local file names can be made explicit using absolute or relative pathnames
61: to avoid
62: .Nm
63: treating file names containing
64: .Sq :\&
65: as host specifiers.
66: Copies between two remote hosts are also permitted.
1.3 aaron 67: .Pp
68: The options are as follows:
69: .Bl -tag -width Ds
1.29 jmc 70: .It Fl 1
71: Forces
72: .Nm
73: to use protocol 1.
74: .It Fl 2
75: Forces
76: .Nm
77: to use protocol 2.
1.55 markus 78: .It Fl 3
79: Copies between two remote hosts are transferred through the local host.
80: Without this option the data is copied directly between the two remote
81: hosts.
1.56 ! jmc 82: Note that this option disables the progress meter.
1.29 jmc 83: .It Fl 4
84: Forces
85: .Nm
86: to use IPv4 addresses only.
87: .It Fl 6
88: Forces
1.3 aaron 89: .Nm
1.29 jmc 90: to use IPv6 addresses only.
1.3 aaron 91: .It Fl B
1.1 deraadt 92: Selects batch mode (prevents asking for passwords or passphrases).
1.3 aaron 93: .It Fl C
1.6 aaron 94: Compression enable.
95: Passes the
1.3 aaron 96: .Fl C
97: flag to
98: .Xr ssh 1
1.1 deraadt 99: to enable compression.
1.29 jmc 100: .It Fl c Ar cipher
101: Selects the cipher to use for encrypting the data transfer.
102: This option is directly passed to
103: .Xr ssh 1 .
1.19 stevesk 104: .It Fl F Ar ssh_config
105: Specifies an alternative
106: per-user configuration file for
107: .Nm ssh .
108: This option is directly passed to
109: .Xr ssh 1 .
1.29 jmc 110: .It Fl i Ar identity_file
1.46 djm 111: Selects the file from which the identity (private key) for public key
1.29 jmc 112: authentication is read.
113: This option is directly passed to
114: .Xr ssh 1 .
115: .It Fl l Ar limit
116: Limits the used bandwidth, specified in Kbit/s.
117: .It Fl o Ar ssh_option
118: Can be used to pass options to
119: .Nm ssh
120: in the format used in
121: .Xr ssh_config 5 .
122: This is useful for specifying options
123: for which there is no separate
124: .Nm scp
125: command-line flag.
126: For full details of the options listed below, and their possible values, see

1.4 markus 181: .It Fl P Ar port
1.6 aaron 182: Specifies the port to connect to on the remote host.
183: Note that this option is written with a capital
1.3 aaron 184: .Sq P ,
185: because
186: .Fl p
187: is already reserved for preserving the times and modes of the file in
188: .Xr rcp 1 .
1.29 jmc 189: .It Fl p
190: Preserves modification times, access times, and modes from the
191: original file.
192: .It Fl q
1.43 djm 193: Quiet mode: disables the progress meter as well as warning and diagnostic
194: messages from
195: .Xr ssh 1 .
1.29 jmc 196: .It Fl r
197: Recursively copy entire directories.
1.45 dtucker 198: Note that

200: follows symbolic links encountered in the tree traversal.
1.10 deraadt 201: .It Fl S Ar program
202: Name of

1.12 aaron 204: to use for the encrypted connection.
205: The program must understand
