Damien Miller22c77262000-04-13 12:26:34 +1000[diff] [blame]44.Sh DESCRIPTION
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]45.Nm
Damien Miller450a7a12000-03-26 13:04:51 +1000[diff] [blame]46copies files between hosts on a network.
47It uses
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]48.Xr ssh 1
49for data transfer, and uses the same authentication and provides the
50same security as
51.Xr ssh 1 .
52Unlike
53.Xr rcp 1 ,
54.Nm
55will ask for passwords or passphrases if they are needed for
56authentication.
57.Pp
Damien Millerb508faa2008-02-10 22:28:45 +1100[diff] [blame]58File names may contain a user and host specification to indicate
Damien Miller450a7a12000-03-26 13:04:51 +1000[diff] [blame]59that the file is to be copied to/from that host.
Damien Millerb508faa2008-02-10 22:28:45 +1100[diff] [blame]60Local file names can be made explicit using absolute or relative pathnames
61to avoid
62.Nm
63treating file names containing
64.Sq :\&
65as host specifiers.
66Copies between two remote hosts are also permitted.
Damien Miller32aa1441999-10-29 09:15:49 +1000[diff] [blame]67.Pp
68The options are as follows:
69.Bl -tag -width Ds

Damien Millerf1211432011-01-06 22:40:30 +1100[diff] [blame]78.It Fl 3
79Copies between two remote hosts are transferred through the local host.
80Without this option the data is copied directly between the two remote
81hosts.
Damien Miller907998d2011-01-06 22:41:21 +1100[diff] [blame]82Note that this option disables the progress meter.

92Selects batch mode (prevents asking for passwords or passphrases).
93.It Fl C
94Compression enable.
95Passes the
96.Fl C
97flag to
98.Xr ssh 1
99to enable compression.
100.It Fl c Ar cipher
101Selects the cipher to use for encrypting the data transfer.
102This option is directly passed to
103.Xr ssh 1 .
104.It Fl F Ar ssh_config
105Specifies an alternative
106per-user configuration file for
107.Nm ssh .
108This option is directly passed to

110.It Fl i Ar identity_file
Damien Millera034baf2008-07-12 17:12:49 +1000[diff] [blame]111Selects the file from which the identity (private key) for public key
Darren Tucker1f203942003-10-15 15:50:42 +1000[diff] [blame]112authentication is read.
113This option is directly passed to
114.Xr ssh 1 .
115.It Fl l Ar limit
116Limits the used bandwidth, specified in Kbit/s.
117.It Fl o Ar ssh_option
118Can be used to pass options to
119.Nm ssh
120in the format used in
121.Xr ssh_config 5 .
122This is useful for specifying options
123for which there is no separate
124.Nm scp
125command-line flag.
