Damien Miller22c77262000-04-13 12:26:34 +1000[diff] [blame]45.Sh DESCRIPTION
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]46.Nm
Damien Miller450a7a12000-03-26 13:04:51 +1000[diff] [blame]47copies files between hosts on a network.
48It uses
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]49.Xr ssh 1
50for data transfer, and uses the same authentication and provides the
51same security as
52.Xr ssh 1 .
53Unlike
54.Xr rcp 1 ,
55.Nm
56will ask for passwords or passphrases if they are needed for
57authentication.
58.Pp
59Any file name may contain a host and user specification to indicate
Damien Miller450a7a12000-03-26 13:04:51 +1000[diff] [blame]60that the file is to be copied to/from that host.
61Copies between two remote hosts are permitted.
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]62.Pp
63The options are as follows:

Darren Tucker1f203942003-10-15 15:50:42 +1000[diff] [blame]81.It Fl B
82Selects batch mode (prevents asking for passwords or passphrases).
83.It Fl C
84Compression enable.
85Passes the
86.Fl C
87flag to
88.Xr ssh 1
89to enable compression.
90.It Fl c Ar cipher
91Selects the cipher to use for encrypting the data transfer.
92This option is directly passed to
93.Xr ssh 1 .
94.It Fl F Ar ssh_config
95Specifies an alternative
96per-user configuration file for
97.Nm ssh .
98This option is directly passed to
99.Xr ssh 1 .
100.It Fl i Ar identity_file
101Selects the file from which the identity (private key) for RSA
102authentication is read.
103This option is directly passed to
104.Xr ssh 1 .
105.It Fl l Ar limit
106Limits the used bandwidth, specified in Kbit/s.
107.It Fl o Ar ssh_option
108Can be used to pass options to
109.Nm ssh
110in the format used in
111.Xr ssh_config 5 .
112This is useful for specifying options
113for which there is no separate
114.Nm scp
115command-line flag.
